You could buy a used or new powerboat trailer which will take the weight of the boat fully found and able to accept a 23' boat. The last part is important because you will need a trailer which is long enough to back down the ramp and float her on or off without swamping the tow vehicle. Also, the trailer should have a couple of hull guides on the back so that the boat gets centered when you retrieve it at the ramp.
The next thing you'll need is a couple of pressure treated planks. Sandwich them and attach them to the center of the trailers cross members for the keel to sit on. Use a couple of galvanized brackets to do this. It will save having to drill holes in the cross members. The heads of the 5/8" x 6.5" carriage bolts can be counter sunk into the top plank so that the keel won't hit them.
You'll need some extension brackets to raise the bunks to a height of approximately 20". Good luck on that one. I honestly can't tell you what to use or where to buy them.
I was able to purchase 24" extension bracket from a Long Trailer Mfg dealer years ago and they worked for my O'Day 222. Long went out of business years ago.
Perhaps you could weld some adjustable boat stand poppets to your trailer to support the hull.
I can only tell you that the extension brackets on my trailer are the best I've ever seen and it's a shame that some company doesn't start manufacturing them again. These brackets are the key to converting a powerboat trailer into a sailboat trailer.
I bought my Long Trailer new and it came with 8" extension brackets and the dealer had the 24" extension brackets in stock. I really lucked out.
The brackets for the keel boards can be obtained free at any power company. They're used for lightning arrestors, pot heads and fused cutouts. The linemen sometimes mount this hardware to a pole with a 5/8" bolt and have no need for the back plate and the carriage bolt hardware. They wind up throwing it out. I'm sure they would give it to you for the asking. You need at least two back plates with the carriage bolts and washers.
Good luck Gordon!
