| | | This office has designed its share of large custom yachts, but our enthusiasm for smaller boats remains undiminished. We have found that small-boat sailors often derive far more satisfaction from their modest craft than jaded jet-setters do from one of their extravagant toys, and this has reinforced our continued determination to treat our smaller designs not as less significant, only less big. We have great pride in applying the same standards to all our work. Our previous designs for Precision Boat Works are the Precision 18, one of the simplest and most affordable trailerables that can be practically cruised, and the Precision 23, one of the biggest cruisers that can be practically trailered. Our new Precision 21 design has been sized to fit right between her two sisters and is intended to appeal to sailors requiring neither the minimum cost of a mini, nor the extra space of a maxi-trailerable. The great care that both designer and builder have put into the development of the Precision 21 is perhaps most clearly reflected in her interior. Her main cabin berths are laid out properly fore and aft. The optional head can be accessed without having to wake any children sleeping forward, and there is storage for toiletries under this same hinged cushion. The galley is not an awkward slide-away module, but a solidly built-in unit with a stainless sink, garbage bin and alcohol stove. A 48 quart cooler is convenient to both the cockpit and the cabin and there is a large, dry storage area aft, accessible from inside the cabin. The battery box is located outside the living space in the large cockpit locker to starboard, and the centerboard pendant tube is protected by being fully enclosed inside the molded companionway step. For small cruisers, a winged keel is more an inexpensive expedient than it is sensible design. In order to be effective, the wings themselves need to be quite large, which makes them awkward and prone to damage at the launching ramp, and when it comes to mud-banks, it is with good reason that they are referred to as 'Danforth' wings! The Precision 21 features a more versatile and practical keel/centerboard combination, whose NACA 'wing section' foil can be fully extended for maximum efficiency upwind, fully retracted from minimum drag downwind, and left anywhere in between to fine tune the helm on a breezy reach. The board itself weighs only 70 pounds, and it will safely kick up and over underwater obstructions, giving ample warning of shoal water. "Easing off" after inevitable groundings can simply be a matter of raising the board. The cockpit of the Precision 21 is over 7 feet long, and features seats and coamings precisely angled for comfort both with upright and when heeled. The inboard chain plates not only allow exceptionally close-winded performance to weather, but they leave ample side decks clear, providing unobstructed passage past the sleekly styled cabin house to the anchor locker forward. Precision Boat Works shares our enthusiasm for small boats, and they have always executed our designs with meticulous care. Jim Taylor | Standard Equipment Hull and Deck - Iso/NPT gel coat finish

 Precision 21 vs O'Day 192- Thread starter GordoSK
- Start date Sep 13, 2011
- Forums for All Owners
- Trailer Sailors
Hello, I am a new sailor currently taking lessons and I am considering the two boats (Precision 21 and O’day 192) that are for sale in my area. My master plan to trailer to the 5 lakes I have available within 30 minutes of my home, one lake is a mile away. I would like to spend a couple/few years getting experience then spend time in the Apostle Islands and Door county Wisconsin. I like the concept of the combination Shoal Draft Keel and Centerboard. The Oday is listed as $2200 cheaper, but feel it might be too small to spend any significant time on with the possibly of up to 2 adults and 2 kids. I might need to upgrade boats in a couple of years. With the Precision I think it will be large enough to Camp, but not too large to Sail/trailer. But is it $2200 better? My family has experience sleeping in close quarters, since we do pop up camping, Canoe camping, and backpack camping. Thanks for your time and your thoughts chris  Forget the money, get the Precision. You'll never be sorry.  Chris, Size DOES matter. If you're planning on spending time on the boat, go bigger. We bought a Lancer 25. It's the perfect boat for us. 1) The headroom is around 5'-10. 2) It has an enclosed head (but not very big) 3) It has a shoal keel, draws 30". We sail it all over mid-coast Maine, no more than 10 miles out and nothin' bigger that 8' waves. I'm not necessarily advocating a Lancer. Some folks really don't like them. I am, however, suggesting that you go a little bigger. I think you'll be happier on that long weekend with the Mrs. On the smaller boat, if she needs to tinkle (or more) it means a porta-potti in the middle of the salon, for all to see. This doesn't bother some folks. If I may be so bold, before you buy, pick up a copy of The Complete Trailer Sailor by Brian Gilbert (or something like it). I got a copy for $9 on Amazon.com. Gilbert covers all sorts of trailering and sailing subject but most importantly, he has 50 or so trailerables in the back with photos, specs, details, pros and cons. It can help you decide what's best for you. We didn't but we really got lucky. Some of the boats we were considering would still be on the hard in the driveway. Good luck! Don Go with the P21. The wife and i just did first overnight in our P18, It was crowded for just 2 people. Precision Boat would be my choice of course If all other things (size,condition,trailer,etc) are equal. David  I agree on the size and would look to something that is as big as your budget allows if you want to spend more than just a day or two on the water at a time. The cockpit size will be as important as the interior size. I looked at some of the Precisions and they look like a lot of boat for one that is only 21 feet. It looks like they don't take much draft, but look quite high on the trailer in pictures I've seen. If you are doing a lot of trailering to different lakes I'd be concerned about getting the boat into the water with whatever tow vehicle you have. Maybe their tongue extends. I'd want a boat that is easy to launch and also one that is quick to setup once at the ramp. Whatever you choose have them launch and setup and retreive once for you if possible and see if that is acceptable to you and your family. If it is a pain or needs the 'just right' ramp that could effect how much you use the boat. Here is a MacGregor video that shows some of the ramp situations.... http://video.google.com/videoplay?docid=7076785769434785211 ...I'm not saying buy one, but if you want to use the boat a lot at different places getting it to and in and out of the water will be a big issue. Maybe more so than how well it sails. The best of luck, Sum Our Endeavour 37 Our Trips to Utah, Idaho, Canada, Florida Our MacGregor S Pages Mac-Venture Links  I'd agree with the other replies and suggest going with the roomiest boat your budget and tow vehicle can safely handle. We bought a Hunter 23 and it's just enough room for two adults overnighting. I had a 20' Hunter previously and now already thinking about 25+ footers. Good luck in your search! For the past 10 years we have sailed a 1985 Starwind 223 in sailing venues from the Florida Keys to The Long Island Sound. The Starwind was designed by Jim Taylor who also designed the Precision 21. The short keel/ centerboard combo design provides the benefits of a fixed keel with the convenience of an easy trailerable boat. We have sailed that Starwind in weather where much larger boats were afraid to leave the dock. I consider the boat to be safer than one with a swing ballasted keel and more stable than water ballasted vessels. Never buy a boat that from the onset you consider it to be to small. Somehow it will just continue to get smaller and you'll probably end up loosing money just getting rid of it within a year. I vote for the Precision.  Make an offer on the P21, but not full price. Perhaps you can knock that $2200 price difference down a bit. Based on my experience, I'd get the O'Day now and look for a larger boat later when you are ready to do some cruising. A smaller (more easily trailered/rigged) boat will probably get sailed more at your local lakes. For cruising, a larger boat(P-23 or similar) would be great. Its hard to find one boat to do everything with. I started out with an O-Day 22 but ended up with three boats which all get used depending on where I am going and how much time I have. Besides, looking at and fixing up older boats is part of the fun of sailing. Thanks all for your feedback and suggestions, I have deciding to go with the Precision 21, I pick it up on Saturday. I look forward to spending many days getting to learn her and sailing, I do plan on naming her since the boat does not have a name, I dont have to worry about jinxing it. chris That's a good choice! If you're not familiar with trailers, have someone check over the wheel bearings and tires very carefully. You still have decent weather where you're located to sail much into the fall?  I would go with the Precision 21. I love my O'Day 222 but the O'Day 192 is a little small for overnighters with a family. Also, both of these boats have been known to have serious rudder blade issues. both ?

My plan was to continue taking lessons with the new (to me) boat and hopefully go by myself a couple of times through October, I have inside (heated)storage lined up for the winter starting in November. Chris, We have a standing rule here a SBO; "No pictures, didn't happen." Spoil us. Don After I little rough ride back, she's in the driveway... Attachments Nice Boat!!!!! Very nice! First time towing a bigger boat is always stressful. - This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

Rig and SailsAuxilary 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 RatioA 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 RatioA 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 RatioA 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 RatioThis 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 FormulaThis 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.
