Antone know or own this boat? It's a 20 foot, 1850 lbs displacement swing keel boat with 185 square feet of sail. It is said to be slow by some who have owned one. Just wondering how slow? Also what makes a design slower than another? Is it mainly displacement vs. sail area? Does swing keel = slow? Hull shape has something to do with it I am sure too. Thanks, Eric

looks like a cute little boat. swing keel does not becessarily equal slow.  

Here is a pic from the original brochure....

PHRF average is 285, which puts it slower than the Balboa 20 or ComPac19, both famously pokey boats. But who cares? All sailboats are slow. You can pay $10 million for the latest canting-keel, carbon fiber racer and go as fast as ... a person on a bicycle. So once you get your head around that, it becomes a matter of HOW slow a sailboat is -- and more importantly, how slow it feels. A Hobie 14 is slow, a Sunfish is slow -- but they sure feel like they are ripping along. Helm response, acceleration, heeling, pitching all contribute to a boat's feeling of excitement. Hard to advise on that. From the picture you posted, I'd say the mast is short and the mainsail very small, roachless. Can't even see the purpose of that first set of reef points. Long spreaders and jibsheets outside the shrouds suggest it's hard to get a fine slot between the sails; that'll rob your power. It's a beamy bugger that carries its width well aft, so it'll be stable but with some drag. Cockpit looks comfy, nice fat rails to sit on, looks like a recessed traveler mid-boom. Appears well set up and ready to sail. I like it. If you can arrange a test sail, see if it feels heavy or quick. Edit: just noticed the red boat in your first post lacks the traveler; may be set up for boom-end sheeting. on this boat, I'd call that a demerit. Not a huge one, but still.  

The only other boat I have sailed (crewed really) close to this size was an Edel 540. How does this boat compare to it for speed? Here are some more specs: LOA: 20'5" Beam: 7'7" Headroom: 4'10" LWL: 18'1" Draft 22" Sail Area: 185 sq. ft. Displacement: 1850 lbs. Ballast: 650 lbs Another pic. The keel is a swing keel but I think it swings into this shoal looking keel. Not sure about how the main is sheeted. I am going to look at the boat this weekend. It's only $1500.00 but is supposed to be in good condition. We will see. I thinks it's been painted all over. I am not holding my breath. Anyone know what the little blackboard on the right side of the transom is?

http://www.ussailing.org/phrf/Tool_ HI_LO_AVG Report.pdf Here is US Sailings hi, low ae ratings for a number of boats. I have not looked to see if this boat is on the list. To me anyway, this boat looks like it could be a good boat depending upon what it is your after. For $1500, you should be able to sell her for what you paid for, maybe a bit more if it needs some cleaning up on the inside. Outside, looks good, but as you mention, it may be new paint, which in and of itself, is not all bad either! Marty  

Hey, my current boat is listed there. A Scirocco 15 (miss-spelled tho, it should be Sirocco 15). It is listed as a PHRF of 348. This means the DS 20 is the faster boat? Eric  

ds 20 sailboat

Yep. You'll be giving Starwind 19s a run for their money.  

ds 20 sailboat

Depending upon where you are located, your choices may only be beating or running! As it is here in puget sound. Then the wind can change from nice weather are northerly winds, low pressure/bad weather, the wind is out of the south! So a weather front comes in, or out when you've gone on way, and the next day can be going the opposite way! Anyway, yes the DS20 should be faster overall than your current boat. BUT, compare it to the new LaserSB 20'r, and that is in the upper 90's IIRC?!?!?!?! so it will pass you like your sitting still, in either boat! marty  

Well, I went to see this boat. It's really old and really solid. Built like a tank. Heres the deal: -It needs all new running rigging. -Sails are old but reasonable looking. -The tangs on the mast for the shrouds need to be replaced. They must have broken or at least cracked because they have been welded. -The forstay and shrouds are 1/8" SS cable and looked good. No broken strands. -The chainplates looked good. They don't fasten to a bulkhead but flat to the inside of the hull. -The backstay is galvanized cable and there was some tackle on the bottom. I assume this is for adjusting the backstay tension? -The interior incorperates a big one peice liner which seemed really solid. One problem with this is there was no way to see what's under the sole of the cabin. I could look in lockers on the cabin benches and see the inside of the hull but the area under the sole is not accessible. -No bilge pump - and I don't know where one should go. The area under the cockpit is isolated from the area under the cabin which is isolated from the area under the v berth. -Electrics need totally redone -Decks solid -Cockpit solid -No outboard -The whole boat needs TLC cosmetically -The "blackboard" on the transom is a solar panel. I have no idea why it's mounted there. I kind of like the idea of fixing this one up. I have the time and skills and the tools to do it. I would need to find the space, since I can't do it at home. The mainsail boom control is some kind of triangular arrangement (sheet goes from the rear of boom to port side to boom to starboard side where it gets cleated in a cam type cleat. I have no idea how this arrangement works or if it's a good thing. The guy has had it for sale for a year. He wants 1500.00 and he want's it gone pretty bad I think. I am considering offering him $500.00 if I can find a place to work in it. Eric  

Similar boat Hey! Did you actualy buy it? I'm looking at a similar boat near my place. Seems in a bit worse condition compared to the one on your pics.  

Similar boat Here are a few pictures of the one I'm looking at...  

She comes with -a couple of hours of work (way more than that, not too sure how many though?); -lots of cleaning; -older suzuki 9.9 (no idea of working condition, the motor wasn't with the boat at the time of inspection) -metal gas tank with 5 year old gas still in it; -battery left in the boat for many years (including winter); -2 probably seized 12V water pump (couldn't try because battery is no good) -4 sails (1 main, 2 genoa, 1 storm jib) all original, and all (except for jib) have rips; -80's dry rotten life vests (5), -very old depth sounder; -equally old VHF (with no antena); -seats are not the greatest color (not too bad since they all need to be replaced, rotten); -all teak needs care; -spreaders both bent; -needs new lines for running rigging; -some weird spots in the deck (see roten wood photo above VHF); -sketchy plumbing; -wiring needs redone; -too much junk all over; -twin axel trailer (custom?) needs to be sandblasted/painted; -rudder blade slightly bent to port; -bulkheads are wood cover with paint&glass many need to be recovered; -unsure of proper swage system plan (see plumbing); -no aft railing (were they standard, I think so judging from DS20 photos I have seen...); -raising/lowering keel mechanism seems functional (but no means of testing it, nor seeing if there is any aft keel section left/damage.) I'm also a bit concerned by the thickness of the hull (is it just me or there is not much fiberglass on this thing?) He wants 4000$ (can) for it and wants it gone before snow comes. Willing to offer 800 if engine works... Reasonable?

AllThumbs got that boat, I believe, and posted extensively on the work he did on it. You should be able to find it in a search.  

I didn't get this one. The seller scoffed at my rediculous offer, but I did buy another just like it for $750. It's a good boat. There is enough glass. The light you see thru the glass from the inside is normal. These boats come in shoal draft or centerboard (swing keel) The shoal draft is just the centerboard boat without the board. Some folks complain about the shoal draft version and it's ability to point. My boat was sailed all summer by me and it points just as well as any other non racer. Watch the keel as some get water in them and then bust when it freezes. Mine was alright. Yours looks a little better than mine inside. I am working on my interior this winter. Ask any question you like and I will try to answer. I would say yours is worth $800 as is. I paid $ 750 for mine. Here is the thread of the refinish job I did. http://www.sailnet.com/forums/gear-maintenance/48179-my-project-boat.html

Here we are sailing ours this summer. I think she made a pretty sailboat.  

Vehicle Water transportation Sailing Boat Sailboat

I have done nothing structuraly to my deck. The boat uses plywood backing plates under the hardware, and this is what you are seeing in those pics. They seem to be glued in place and then the edges of the plywood camfered back to the underside of the deck using some sort of filler. I would not be too concerned about these bits of plywood. They are not the "core" of the laminate but rather glued to the outside of the laminate on the bottom. At least on my boat. This winter, I may try to peel some of these backing plates off and replace with aluminium. We will see. The core on the early DS boats was regular 1/4" pegboard. I guess the thought was that since it has holes every few inches, it would allow the top and bottom layers of the laminate to be bonded together thru the holes. The pegboard was used on the cabin top and forward deck. I suppose it could get wet and rot, but mine seems to be pretty solid and the peg board doesn't seem to wick a lot of water the way balsa core does. If you look closely, you can see the pegboard holes as dimples in the laminate. See pic below. Look closely where the light reflects on the center part of the hatch. My boat needs some smaller bulkheads below the cockpit replaced, altho I sailed it all summer as is. Mine are not rotten, but rather delaminated from the tabbing due to being wet for so long. The bilge on these boats is shallow and wide, so any water in the bilge covers a large area, and right up against a plywood bulkhead (the one that keeps bilge water out of the cabin). I plan on replacing these bulkheads with sheets of solid 1/4" fiberglass and then tabbing them in. Eric  

after.jpg

Here is the state of my bilge area and the two bulkheads in question. These seem to have been replaced once before. These will be replaced with fiberglass sheets. Everything will be cleaned up and painted too. Eric

DS-20 is a 20 ′ 4 ″ / 6.2 m monohull sailboat designed by Diller & Schwill and built by DS Yachts (Schwill Yachts) between 1972 and 1983.

Drawing of DS-20

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

  • SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
  • D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

  • D: Displacement of the boat in pounds
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

A Mark II version had more interior amenities. A few boats have a shallow draft fixed keel. At least 160 built.

Review of DS-20

Basic specs..

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.

The boat is equipped with 75.0 liter fresh water capacity.

The boat equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a genaker or a spinnaker for optimal speed.

The DS-20 is equipped with a swing keel. A swing keel is a pivoting lifting keel, allowing to sail both coastal and inland waters.

The boat can enter even shallow marinas as the draft is just about 0.56 - 0.66 meter (1.84 - 2.14 ft) dependent on the load. See immersion rate below.

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

What is Capsize Screening Formula (CSF)?

The capsize screening value for DS-20 is 2.47, indicating that this boat would not be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 5.7 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for DS-20 is about 85 kg/cm, alternatively 477 lbs/inch. Meaning: if you load 85 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 477 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

What is Motion Comfort Ratio (MCR)?

What is L/B (Length Beam Ratio)?

What is a Ballast Ratio?

What is Displacement Length Ratio?

What is SA/D (Sail Area Displacement ratio)?

Maintenance

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 15m 2 (161 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.

Reader Boat: DS20 "After School"

Article by Eric Van Andel

ds 20 sailboat

About five years ago, in my early forties, I was a beginning sailor. I bought a 15-foot dinghy to learn on and sailed it on a tiny reservoir north of Woodstock, my hometown in southwestern Ontario. After one season, I knew I wanted something a little larger. It had to be trailerable, maybe about 20 feet in length. Oh, and I wanted a fixer, and it had to be cheap. Knowing very little about sailboats, those were really my only criteria. I started looking online at used boats.

I found a 1973 DS20 in a town three hours north. It was red—and ruined. I loved it. He wanted $1500, and I offered him six. He scoffed, suggesting I purchase a canoe. I was devastated, but not as devastated as I am stubborn, so I left. A week later another red DS20 appeared online. Same year, same price, different boat, different seller. Again I make a long drive. Again, it’s perfect: bad bulkheads, sketchy sails, rough rigging, tattered trailer, and profound potential. Again, I offer the guy $600. I wince, but he’s not offended. He seems to be considering it. Now’s my chance, I think. I sweeten the deal, just a little, while pointing out its condition. He sighs, but I can see he trusts me. He knows she will sail again, and to a sailor who has had countless hours of joy on a small sailing vessel, the thought that his vessel might bring joy to another has value that is not expressed in dollars. He agrees, and it’s mine, for $750.

Nordship 420 DS: The boat that offers everything

Graham Snook

  • Graham Snook
  • January 30, 2023

Centre cockpit, deck saloon yachts with full-beam aft cabins seem to offer everything, but is the promise too good to be true? Graham Snook heads to Denmark to find out

The Nordship 420 DS sailing with grey and black sails and a white hull

Product Overview

Nordship 420 ds.

  • Deck saloon living
  • Full beam aft cabin
  • Excellent workmanship/build quality
  • Helm feels high when standing
  • Crew are essentially redundant
  • Standing rigging crosses the deck

Manufacturer:

Price as reviewed:.

Boats like the Nordship 420 DS are rare.

On paper, centre cockpit, deck saloon yachts, with full-beam aft cabins have everything; a vast full-beam owner’s aft cabin that can be ensuite, a raised saloon with 360º views out, and a well-protected centre cockpit.

On top of that, you get everything else you expect to find on a 40-45ft yacht (second heads, large galley and a vee berth forwards).

So why aren’t there more on the water? OK, they are not cheap.

You can find many aft cockpit deck saloon yachts lacking a full-beam aft cabin, and centre cockpit yachts with full-beam aft cabins but no deck saloon.

By combining all three features in its range of cruisers over 38ft (it does make the 360 DS but the aft cabin is not full beam), Nordship creates an enigma that few others offer.

Hull Number 1 from any builder is often a work in progress, but after four hours poking around the Nordship 420 DS, the only issues I could find were (spoiler alert) a few upper corners in cupboards that hadn’t received the grey flow coat, a few odd placements of lights, and a spring strut in the engine compartment that was desperate to detach itself.

Hull Number 2 was in build and I saw these had been rectified.

Thomas Dan Hougaard, joint owner of Nordship Yachts since merging with Faurby Yachts, explained that every boat depends on what an owner wants, and every boat is a prototype that Nordship must get right.

It’s always a conundrum reviewing yachts where an owner chooses their layout, in a finish and style they want. What you, good reader, or I might find impractical, an owner may find irreplaceable.

You may think the deck and cockpit remain the same, but Nordship will alter the moulds to raise seating or even build female hull moulds without plugs to make full-custom yachts.

If you can afford it, Nordship will make it.

Boarding in the Baltic

So, let’s see how we get on, literally. Getting on a yacht in the Baltic is usually via the bow, and the Nordship 420 DS includes an integrated boarding ladder in the GRP bowsprit .

As well as provide attachments for a code zero or asymmetric sail, it covers the bow roller where the chain passed through the stem, keeping ground tackle below deck level and decks mud-free.

There are large mooring cleats and, without a spare roller on the bow, they’ll be needed when picking up a mooring.

In the anchor locker is a windlass, the shore power connector, and large hooks for warps and fenders. Beneath the locker is a watertight crash box.

Nordship has redesigned the window line across the range. Gone are rounded clear windows in anodised aluminium frames, replaced by double-glazed tinted windows with black-painted mullions appearing to be a single wraparound window.

The deck of a yacht

All lines on the Norship 420 DS are led aft under the coachroof. Credit: Graham Snook

It’s a neat trick that gives the boat a surprisingly modern look, without the increased cost of custom-made curved glazing.

Above the side windows are moulded GRP overhangs, and the inboard edge of these are cut away to create a full-length coachroof handhold.

The chainplates are taken outboard of the teak deck, but the D1s (the lower diagonals of the standing rigging) and the raised coachroof conspire to make negotiating them a little awkward.

Getting to the cockpit, those with long legs can step over the high coaming just aft of the spray hood, but most will go a little bit further along the side decks and step over the genoa winches .

All lines are led back under deck to the helm and a winch on either side.

Standing at the large single wheel, I felt high and a little vulnerable, but sat on the broad raised coamings, found around the helm, it felt far more secure.

The wheel pedestal offers good bracing for feet. Rails, like a pushpit for the cockpit, are available and if I wanted to cross an ocean, I might be tempted to get them as a backrest which would make the seating more relaxing – like the pushpit seats to the rear.

She felt really good on the helm. It was light, with a pleasant involving feel.

Having seen the 0.5m (1ft 7in) deep skeg that the rudder stock passes through, the boat was more agile than I was expecting.

She has a sure-footed feel and, even when well-heeled, she showed no signs of losing grip.

The single wheel does make reaching over and around it (for engine/instrument controls) a little tiresome.

Sailing in these unfamiliar waters, with the central chartplotter away from the most comfortable seating, I felt obliged to stand.

Calm contender

We had a decent south-easterly Force 4-5 breeze, enough to kick up some chop with the wind against the tide flowing into the Little Belt after weaving its way past Middelfart on the island of Funen (Fyn).

She made short work of it without a squeak from the interior or any slamming on the hull and kept a good speed in the process.

The hull was originally that of the Nordship 40 DS. It’s foam-cored to the waterline and solid laminate to the bilge sump.

The keel is GRP; bolts are laminated in the top and bottom, and through the fin, attaching it and its lead ballast to the hull.

This method keeps the full weight of the ballast as low as possible.

Within the hull is a bonded galvanised steel frame that takes the loads from the keel and the mast compression post.

Where the cabinetry and bulkheads touch the hull or deck, they are laminated in place.

A raised saloon on a yacht

This boat had electric Andersen 46 primary winches. These, and her self-tacking jib makes her a doddle to sail by one person at the helm – there’s also the option of a 105% genoa with tracks added on deck.

Nordship uses a two-cockpit design; the aft cockpit is for the helm, and the forward cockpit is free of lines and is a sheltered space for the crew.

The other reason for this design is that it gives a 1.75m (5ft 9in) walkthrough across the aft cabin beneath.

On the bridge deck, between the cockpits, is the mainsheet traveller that’s at a comfortable knee height rather than on the sole.

It stops short on either side – to protect the coaming and the feet of any crew long enough to be lying asleep.

The forward cockpit has a central cockpit table with a removable cup holder (with notches for cup handles) and sits over a substantial bracing bar.

When not required, the table can be removed, leaving just the bar as a handhold and foot brace. The hinged companionway bi-fold door is permanently attached.

There is a cockpit locker to port, while the locker is vast, its opening is a little small. There is a locker beneath the helm seat too.

Bespoke design

When you buy a Nordship, you’ll sit down with Nordship’s other owner, and designer, Lars Buchwald and discuss plans and layout ideas.

You may want a lower galley, a mid-cabin or any combination of layouts that work for you. Nordship will customise its boats extensively.

The owner of this boat wanted at least 6ft 3in of headroom in the main area, so the sole of the galley, heads and saloon were lowered, as was the saloon seating.

A large double bed on a boat

The aft cabin has good ventilation and shows of Nordship’s craftsmanship. Fit out is custom, but this bed is 6ft 4in long, and at over 5ft wide, is very comfortable. An ensuite is possible, but not fitted on this boat. Credit: Graham Snook

I’ve long been a fan of the deck saloon concept; one reason we sail is to visit new places, but then sit in low saloons without a view of scenery.

The saloon of the Nordship is the opposite; raised, with excellent views in all directions.

The inboard-facing U-shaped seating is comfortable and the outboard seat is 2.35m (7ft 8in) long. Beneath this seat is a cavernous locker, accessed by lifting the seat base, although access is a bit awkward as the table is fixed.

The downside of a deck saloon is usually a lack of privacy when in harbour. You can feel like an exhibit for promenading people – especially at night.

A galley on a boat

Nordship uses quite a heavy tint on its windows to reduce this, but it also has its snug area.

A few steps down, en route to the aft cabin, three seats create a cosy space with a removable bar cabinet (to convert the two outboard seats to a 2.0m/6ft 6in sea berth) and space for a television or bookshelves opposite.

Whether you’d use this space to enjoy a whisky and a book or for the kids to have a games area or to watch films, it’s one of my favourite areas.

Opposite the saloon seating is a deep locker and the nav station. The chart table can be opening or, as on this boat, have a small drawer instead.

Beneath the chart table, her owner wanted a freezer; I would have preferred drawers. Forward of the chart table is the lower linear galley.

It offers plenty of workspace and has a front-opening marine fridge beneath the seating. The galley is narrow enough to offer bracing on either tack, but still wide enough for two strangers to pass without feeling uncomfortable.

There is plenty of handy stowage in drawers plus deck-level lockers; supplied with crockery.

There is also stowage beneath the galley’s hinged floorboards and in a deep locker in the saloon.

Quality workmanship

To port, is the heads with a separate shower compartment. There is good stowage in front-opening lockers and outboard of the heads.

Forward of the galley and heads is the forward cabin. It has deck-level lockers, two bookshelves, and a well-ventilated hanging locker with an automatic light.

A berth on a boat

Guests will be comfortable in the V-berth forward. A third mid-cabin is an option. Credit: Graham Snook

The 2.0m (6ft 6in) berth was a 0.85m (2ft 9in) step up, which if you need over 6ft headroom isn’t an issue, but for me, at 1.78m (5ft 10in), it felt like a climb.

Thomas said he’d add a step if I bought one.

Saving the best to last, the full beam owner’s cabin is wonderful.

Throughout the boat, the quality of workmanship is on show, but in the aft cabin, you feel pleasantly cocooned in mahogany, hidden away from the rest of the boat.

While not a sports boat, the Nordship 420 DS gave a very assured performance and made light work of choppy water and blustery conditions. Credit: Graham Snook

The berth is 1.58m x 1.94m (5ft 2in x 6ft 4in) and, like the forward berth, it sits on a slatted base for good ventilation.

The cabin has lockers on either side, all with inch-thick mahogany frames.

On the port side, a door leads to what could be an en suite heads but on this boat, access to the cockpit locker.

I’d keep this walk-in locker but just add a toilet and sink to save disturbing guests if I needed the loo at night.

The locker also gives access to the tech area and the engine; starboard side is accessed via the snug with an engine box that has a removable side for excellent access.

Verdict on the Nordship 420 DS

I might have changed a few things on this boat, not because there was anything wrong, but because I could, such is the way of custom yachts.

It’s hard to fault a boat that has been tailored to someone else. If I’d found fault in the craftsmanship, I could pick up on that, but I didn’t.

Whether it’s a fiddle in a seldom-used locker or the grab handles sculpted out of the saloon table, the look and feel of the woodwork was beautiful and irresistibly tactile.

She was enjoyable to sail, hitting the right balance between responsiveness without demanding constant attention.

I did feel quite high up and therefore exposed when standing at the helm, but the 2ft 6in clearance over the aft berth has to come from somewhere. The feeling when seated was much better.

With one foot on the pedestal, I felt ready to sail away and not come back.

Would the Nordship 420 DS suit you and your crew?

The Nordship 420 DS stands out in many ways, but the three main reasons for choosing her would be the huge aft cabin, the social raised deck saloon, and the wonderful craftsmanship with the ability to customise.

OK, that may be four. Yes, there is the snug to keep adults and kids occupied, and lots of stowage too, but if you want a deck saloon with an aft cabin and the ability to make her your own, this is your boat.

She’s solid enough to cross oceans, yet nimble enough to enjoy coastal cruising. Her forward cockpit may leave your crew feeling redundant, but whoever is on the helm has the controls at their fingertips.

In the past, a Nordship could have been seen as old fashioned – like the centre cockpit Moodys and Westerlys of the 1980s.

But take a centre cockpit boat with a spacious aft cabin, add a deck saloon surrounded by tinted wraparound windows, boost her performance with a composite keel, and you get something special.
