I attepted over the holiday break to drop the mast and get my Oday 25 on the old trailer I bought and modified for it. I was able to get the mast down almost uneventful thanks to the wealth of information in this forum. I did have issues with my trailer though. Needless to say, my boat is still parked at the slip and my trailer is back in my driveway for more modifications and a new winch. I would like to modify my keel pad so the boat centers itself on the trailer. Does anyone have the width of the ODay 25's keel on the CB model? Also, what size winch should I get to replace the rusted out and stripped one that is currently on trailer?
Some guys install keel guides on each side of the trailer's keel board. If I were you I would buy some guides that connect to the rear of the trailer. These are just 1" square tube galvanized bars with a couple of 2" X 6' PVC pipes on them. All you do is mount them to your trailer and adjust them so that the boat can get by them at it's widest beam.
Once you get the boat centered between these guides, you should be able to judge whether the keel is straight on the keel board by looking at the guides in relation to the hull. You may have for example 4" on both sides. Later on you'll be able to judge it by looking at just one guide.
As for the winch, I have a Fulton two speed T3205 winch. I mounted a nylon strap on it years ago. It works OK for my O'Day 222 but you never want to put too much strain on these winches. The keels just aren't going to slide on the keel board with too much of the boat's weight on them.
Lately I've been lucky in that I can get my boat's bow right up against the winch stanchion roller with very little problem.
Sometimes a problem can occure when the trailer is pulled up the ramp. The angle of the boat's keel in relation to the trailer angle on the ramp can cause the bow to come short of the stanchion roller by a couple of inches. Some guys use what is called the "MacGregor Bump" to correct this. I don't think it would work well on an O'Day 25 though and personally I wouldn't try it. The only thing I can say is experiment and see what works for you. Here's some pics of my trailer guides. I recommend that you remove the PVC pipes from the guides when you're trailering because the 2" caps can break when you go over bumps on the road. I broke two of them on my pipes.
If you should decide to go with the Nylon strap on the winch instead of the galvanized cable, the nylon will last longer if you keep the sun's UV rays off it by covering it with a piece of polytarp. I've had that strap for many years and it's still in great condition. I think the Nylon can last a lot longer than the galvanized cable if you keep it covered when it's not in use.
