[Putershark]

Not that I recommend it, but I know of several 210 hulls (including our old one) that have sat on 2 / 4 bunk lifts in the hot Florida sun for years and I have not "seen" any negative effects of such... Here again if it is on a lift, they are also in the water more than most boats since launch time (lucky dudues) is very quick and easy I say this not to recommend that you do that same, but that the short time you would have one on a lift to switch trailers is a moot point...

I also have a 4 bunk I-beam trailer for our 190 that I adjusted bunks on to get it to fit just right. And I have to say that with it's "much" longer keel bunks, that I have had much less (if any) of a deflection issue than many 190's I have seen on "factory" trailers

I also have always made it a practice to loosen up the wench strap when I get her back home which I think has help out greatly over the years. What I do is use a tie down strap to then take the load and hold the hull in place and pulling (more like holding) it in a straight down manner instead of the wench "pulling" on the bow on a constant basis. This is a practice I started doing "long" before Triumph was in business and for the very same reason. To relax the forces pulling on the bow when not really needed Trust me, they don't call it fiberGLASS for nothing
