trailer bunk fit - 23 SF

[bigi]

I believe it's 10 degrees at the chine in the patent. Need to confirm it's the 23 in the patent.

I would have thought the patent preceded the 23’ by a few years and maybe it did for a production version of the 23’. Don’t know when Potter arrived, but thought he was instrumental in the 23’.

Per the Moesly story:
His first design using the VDR hull was a 23-footer, all out of plywood, built only to be a test boat. The bottom was painted red and white to highlight the unique feature of the hull... longitudinal steps. Named Si-Vad (Davis spelled backward), it was thoroughly tested in the Miami to Nassau race (1961). It performed better than Moesly expected, but he had a few ideas to make it even better. He shortened the design to 21 feet, made a few adjustments to the longitudinal steps, compounded the curves for fiberglass and increased its load carrying ability. A wood/fiberglass plug was built and a mold produced.

If it's not too much trouble, load the boat on the new trailer, if the bunks are close, and take your measurements. Cut the new angle and adjust the width of the bunks so they catch the outside section to yield a lot more stability. You may be able to cut the height of the bunks down to lower the hull making it easier to unload on shallower ramps. Measure twice, cut once.

My old Hitch Hiker trailer had vertical bunks that I did that way when I replaced the old ones.

Thanks to all! Interesting that I called the dealer that sold and set up the trailer originally and he tells me (and another dealer confirms) that Loadrite doesn't customize the angle of the upright bunks. It's just a standard angle (though neither could tell me what that angle was.

I will likely install the new front centering bunks and adjust the existing rear bunks to meet the hull just inside the chine. I'll see what the angle looks like. If the angle on the bunks looks too aggressive, I may just take the boat home (only about 15 miles) and jack up the boat off the bunks and replace them with adjustable bunks that rest the boat on the face of the bunk instead of the edge, like uncle boo's. That way, I can adjust the angle front and back.
