I've been searching for a new boat trailer for my 92 Barefoot Warrior outboard for 4 months and getting nowhere. Seems nobody had any data for my 92 or even when they were offered the boat for sizing they wouldn't touch it. Well things got worse. The last week in December I found a crack in my hull. Upon further discovery I found the trailer that was made/bought for the boat wasn't designed for the hull. The bunks were never under the stringers and when I lived in Michigan I didn't trailer it much because I lived on a lake. Here in Florida I trailer back and forth to the lake all the time. The center support on the old trailer was right over the axle like a jack hammer to the hull.
Good news, went to J-3 Fiberglass in Ocala on January 3rd, worked out a price and a Date of repair about 10 days out. Left there to find someone to build a trailer for me. Same morning, 2 hours latter and my 3rd trailer shop latter. I pull in at Redline Custom Trailers in Ocala and ask if they can build me a trailer. "Yes no problem" they say. I explain where the bunks have to be with 2 outer bunks at the rear. We agree on a price but they had a boat show the weekend coming up and will start on it next week. I leave the boat and old trailer with them. On January 10th I get a call from Redline, "the trailer is done come a pick it up". Morning of the 11th I pick up my broke boat on the new beautiful trailer. What a difference in the ride, tracks straight and seems to float with a torsion axle. Oh and it looks good to. The following Monday I drop off the rig a J-3 to get the hull repaired and that Friday I pick up my boat, ready for another 30 years. (I should live that long, Ha!)
Moral of the story: How sure are you that you trailer is supporting your boat. If it's a boat manufacture that builds in-house trailers it should be good to go. But unless you swim under or can lift the hull to inspect it you my never know. If you have a boat with a off brand trailer, check to make sure your bunks are supporting the hull under the stringers if you trailer your boat a lot.
