I recall that grid stringer setup from the factory tour a few years ago. Pretty amazing that it is actually suspended 1/4 inch above the hull, and then fiberglassed to it. That must have caused Scott Adams and the engineers many long hours to design and test.
I've also met the family from IL that owns Prestige Trailers, and they are proud of their product, and work hard to build high quality, yet affordable trailers. But, from your picture, they do their bunks differently at the transom than most other high quality builders for offshore boats. Prestige builds more trailers for runabouts, and I THINK the trailers for big offshore boats is a new direction for them. It could be they come at trailer design from a different perspective, without the "baggage" of the Mannings, Mycos, etc. who built trailers for offshore boats from decades ago. Or it could be there is a good reason not to use keel bunks at the transom. I'd really like some trailer builders to start weighing in here.
BTW: Guys, it looks like it might be a while before you can ride in my new 382, but I'm still working on Troutly and his deformed blob of resin that wouldn't even be good enough for Cuban refuges
