I recently purchased a 1984 O'day 26 and am planning to order a new trailer for it. I really have no way to weight the boat. The spec sheets I have seen list the displacement at 4800#. Have any of you who own either a 26 or a 25 with centerboard had your boat weighed? I would appreciate a reply from anyone who has done so.
I don't have any of these model O'Days, but when I ordered my trailer, I sat down with the Long Mfg. Boat Trailer dealer and he had the specs of my 1986 O'Day 222 in his PC and I had brought my brochure with me. The original trailer that came with my boat was a single axle Load-Rite roller trailer 3,175 lbs GAWR. The new Long trailer that I wound up buying is a tandem Aluminum bunk trailer built for a 23' powerboat at 4600 lbs. There are two things that you probably need to take into consideration when you buy a trailer for an O'Day sailboat. The weight of the boat fully loaded with gear, and that, you can guesstimate, and the type of trailer that you're going to buy for this boat. Most of the O'Days have thick strong hulls that can take a roller trailer, which is not the case with other brand boats like Catalina. So you can go with a trailer that is rated for the weight of the boat fully loaded, and the trailer most likely will be a little shorter than the bunk type trailer where you need the trailer length to float the boat off without swamping the towing vehicle. If you choose to go for a bunk trailer as I did, then you'll probably need a trailer that is a little longer so you can float her off. When I bought my trailer, I also opted for the 24" extensions for the bunks and I did the changes myself. I sandwiched two pressure treated planks in the center of my cross members for my keel to rest on. What I would do is, go to a knowledgeable dealer and talk to him. You don't even have to purchase the trailer from him. You only need some information, and he can provide it. The Long dealer can set you up with a complete roller trailer for your boat, if that is what you want, or you can do what I did and make the necessary changes needed to a decent flat bunk trailer to accommodate the hull of your boat.

http://www.longtrailer.com/ I've seen a lot boat trailers, but I've never seen any with extension brackets as good as these. The bracket in the picture is one of the three galvanized steel brackets that I used to hold my planks to the cross members. These brackets can be acquired at a local power company and are used for lightning arrestors or fused cutouts. They don't always use them for some utility pole construction, and they throw them out. If you install a sandwiched keel board as I did, you may or may not need to add an extra cross member to distribute the weight of the keel. Good luck with your choice of a trailer. I was very fortunate and I know that I made the right choice when I bought mine.
