Tim,

The Nacra rules are the same. I sort of agree (sitting on the fence a little) with that though. If not trampolines, where do you stop? Sails? OK, the tramp is not a big performance ticket but it can add to boat stiffness if it's really tight (not to consider the warrantee and market reliability perception if everyone started buying supper tight trampolines and breaking boats). However, Nacra does seem to keep their pricing more in line with the one-off market. I just installed my new trampoline this weekend and according to the Nacra pricing guide (I haven't gotten the final bill yet) my new tramp for my 6.0 was around $350 from the factory. That's about $20 more than I can get an aftermarket one for and not too bad IMO. That Hobie price does sound VERY high.

Actually, I checked again and the Nacra trampoline is $20 CHEAPER than the aftermarket trapolines I found online.
