I have a '77 25 and a trailer that was being customized by the former owner. I need to set it up so that the tongue weight will be approxitely 250 to 400lbs at the hitch which would be about neutral since the trailer has that empty. So, in order to set a keel stop on the base plate of the trailer and a bow roller, I need to know where the fore and aft Center of Gravity is in relation to something I can measure; mast step, bow, stern, front of the centerboard trunk, whatever. SO! Basicly I need to find out what the hull's dimensions are. I need any measurements,photo,illustrations you can send. Thanks, Ira Watkins (idwatkin@alltel.net)

Ira, Make your trailer as
adjustable as possible. There are no canned measurments for your trailer. If I have time tomorrow, I will try to look up some old pics of both of my 25 O'Day trailers. There are so many variables, that you should make the bunks, stands, or rollers as adjustable as possible. I reworked my first trailer and was happy with it but had I done it to the measurements of the old trailer it would have been a mistake. If you are worried about tongue weight, you will have to put the boat on the trailer and move it fore and aft to get it right. The problem with that is the hull has shape, so six inches forward or backwards changes the height of the bunk, roller, stand, by the shape of the boat. The important thing on the 25 O'Day is to have the weight of the boat rest on the keel. Then adjust the supports to fit the boat. On my second trailer, the keel supports have bent and now the limited adjustable rollers have stove the hull in about 1". This is because the weight of the boat is on the roller not the keel. r.w.landau

Hull measurements side view
Here are some measurements I took when I was modifying a trailer. Maybe this will help.
