O'Day 25

O'Day 25 is a 24 ′ 10 ″ / 7.6 m monohull sailboat designed by Raymond Hunt (C.R. Hunt & Assoc.) and John Deknatel and built by Bangor Punta Corp. and O'Day Corp. between 1975 and 1984.

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)

One of company’s most successful models and in production for nearly a decade. A majority were delivered with a keel/cb, but a fixed keel version was also available (Draft:4.50’/1.37m), as was a taller rig. I: 32.00’ / 9.75m J: 10.60’ / 3.23m P: 26.50’ / 8.08m E: 9.00’ / 2.74m Yanmar inboard diesel available as an option.

Complete engine information will be updated as soon as possible. Everything looks to be in great working order; this boat was built well to last. Stock #109867 1979 O'DAY 25 OMC GAS ENGINE AND INCLUDES TRAILER EASY TO TRANSPORT Great sailing boat, very easy to handle. Convenient that it is trailerable an has reclining keel. She goes to windward in a chop, because she has both a centerboard and a keel. The centerboard gives her a 6Ft draft which makes her fast and close winded and helps her track when waves build up. With her board up you can slide into coves or shallow bays for a quick swim or to anchor for the night. The cabin is spacious and well appointed. Cushions match fish print trim, which are being stored at owners home to keep them clean and like new, (not shown in photos). Privacy with full folding doors, and decent space for cooking and plotting a course in comfort while the boat is heeled over. Reason for selling is wife passed away.

1986 O'Day 31,This isnt just a boat, shes the newest member of your family! Over the course of the last 5 years Ruff Life has taught her current owners how to be sailors. They love everything about how she sails so much that they are staying in the ODay family and moving up to a larger version to accommodate their growing family. Ruff Life hails from Ann Arbor, MI originally but her current owners sail her on the Potomac River and Chesapeake Bay. She enjoys winds from 10-15 knots and will give you a gentle heel for a relaxing sail. Looking for a bit more adventure, she has taken on 20-25 knots which allow you to hang off the side and get your toes in the water! Her current family loves her ability to sail briskly under only the 155% genoa while resting the mainsail and maintaining plenty of cruising speed. Her cabin is nicely arranged, very large, and welcoming. She is equipped with an abundance of storage. Throughout their time together, the current owners have maintained her and updated / upgraded many parts to include a new dodger, new life lines, new headstay and new jib reefing configuration, new LED lights throughout, new portlights, custom mattress topper for the v-berth, and several layers of new bottom paint. The auxiliary power has been meticulously maintained and updated with a new alternator, new water pump, new heat exchanger, new starter, rebuilt raw water pump, rebuilt injector pump, and rebuilt transmission. Nothing has been neglected or forgotten on this lady. This isnt just a boat sale to the current owners, this is an adoption of one of their favorite members of the family!

“ I just received my asymmetrical spinnaker, with sock and turtle bag, along with a new 135 Genoa. The entire process was simple and both sales and the design team were in regular contact if there were any questions. The customer portal was easy to use and lets you keep track of where in the process your sails are. Great sails, great service -Graham Edwards (Facebook)

“ The whole team at Precision Sails was fantastic from start to finish. We’ve had a laminate main and genoa made so far and have a spinnaker on the way. They listened carefully to our needs and recommended a great sail cloth. We couldn’t have gotten more bang for our buck! -Noah Regelous (Google)

“ We received our spinnaker and launched it yesterday and I just wanted to let you know how pleased we are with it. The service we received from your company was exceptional and the quality of your product is second to none. We will certainly be return customers in the next few months to replace our main and jib sails and will recommend your company to all our sailing buddies. Once again-thank you.” -Daniel Jackson (Google)

“ we had good communication during the planning stages and the knowledgeable people at precision sails really got me fixed up good! The sails look and work fabulous! my boat sails better than it ever had! couldn’t be more pleased with the product AND the service!” -Fred Jelich (Facebook)

“ Our new furling jib for a Corsair 27 Had to be specially designed due to the height of the furler, but this was accomplished quickly and in short order we had our sail which fits beautifully and has a great shape. It’s everything we could have wanted, high tech design, thoughtfully executed and affordable.” -Nancy Y. (Yelp)

O'Day 25 Keel / Centerboard ?

• Thread starter Doug Daniel
• Start date Nov 3, 2005
• Oday Owner Forums
• Ask An Oday Owner

Doug Daniel

Can someone tell me whether the O'Day 25 in Keel/Centerboard configuration is really a centerboard ? I see many mentions of swing keel. Is it a huge, heavy swing keel, or a modest weight centerboard. I am currently looking to buy one of these boats.Doug Daniel434-841-4034  

A very nice boat The centerboard on the Oday 25 is relatively lightweight (as compared to the true "swing keels" on the Catalina 22 and 25). It probably weighs about 50 or 60 lbs. The ballast for the Oday (about 1500 lbs I think)is encapsulated in the stub keel. The board is light enough to be controlled by a single pendent line; no crank or block and tackle.The Oday 25 is a nice boat. If you are looking for a comfortable day sailer with overnight or weekend accomodations, its a keeper. The only other boat in its price range that I think is comparable is the Catalina 25. The Catalina has some advantages over the Oday: the option of a pop-top cabin, the option of a tall rig, the option of a fixed fin keel, and a manufacturer still in business that will support your maintenance efforts. However, the Oday is superior to the Catalina in that most of the Catalina 25's were made with swing keels; I don't like the idea of all of my boat's ballast swinging around on one pivot pin and relying on a crank for adjustment. The Oday with the stub keel and centerboard sails better and points higher than the Catalina swing keel. Also, all other things being equal, the Oday will probably be cheaper to buy than the Catalina. Bottom line is both are really fun, nice boats.  

Thank You ! Thanks Much for the information. I agree with you, I do NOT want the huge ballast swinging under the boat. I do however, like the idea of Keel/CB.Doug

another option You might consider the O'day 23. They are also shoal draft with a centerboard. The galley and sink slide under the cockpit to give excellent amount of room below. Mine is a '79 and we just love her. Good Luck

O'Day 25 CB I have an O'Day 25 centerboard. It is indeed a true centerboard. The keel weights 1825 lbs, and the centerboard weighs 60. When you see someone mentioning O'Day's "swing keel", it's a misnomer. All of their boats were either fixed keel or centerboard/trunk models.Even though O'Day is out of business, parts are easily obtained from D&R Marine (he's a former employee).Also, O'Day did make a "tall rig" (I think it's 2 feet taller) with a fixed keel.  

Draft? When referring to the draft of this boat, is that figure with the center board (swing keel) up or down?

Should be two numbers for draft..... ....with a keel/centerboard arrangement. In the case of the O'day 25 it's 2'3" with the board up and 6'0" with it down, according to the 1975 brochure. For comparison purposes, the fixed keel version of the 25 draws 4'6"  

CB vs Swing Keel I had to order a new centerboard pendant today, and figured I'd get the information straight from Rudy (he used to work for O'Day when they were in business).O'Day never made a 25' swing keel. The 1975 O'Day had a crank for the centerboard in the cabin, but it was still a centerboard.However (contrary to what I've heard) they made a few 23's that had a cast iron swing keel, but discontinued the practice because of the problems they had with them.The only "validity" I can assign to this is that I definitely heard it from Rudy.
