gcc_mtl, I think you may be asking the wrong question. Composite boats are ok in any class of whitewater -- until they hit something or wrap. Some layups might puncture or even break in half if the boat wraps. I think Tuffstuff as demonstrated it will survive a wrap well enough to be paddled out. My Echoee (innegra) has taken a lot of hits with no real damage. Royalex could definitely stand a lot of abuse.
The class of whitewater a boat can manoeuvre in is more a function of its design than materials. Generally, a boat with 2" or less rocker will fill quickly in Class 2+ and will not be able to turn quick enough to manoeuvre well. Whitewater tandems generally have about 4" of rocker. There are other design elements that affect how wet a boat is, but the big one is rocker.
Thank Peter K.
The rapids in LaVerendrye are really short. Im not worried about water filling in. The main concern isn't wrapping either. Indeed, I havent expressed myself properly. Since my rapids are easy, rocker is more about being able to pivot than water concerns, so far 2" has handled well. I already have a Nova Craft royalex prospector for the trips your referring to.
I want:
- light portages
- enough resistance to handle a bump
If costs is not a concern, what is the lightest layup that can take a lateral hit as I pass by a rock, or a direct bow hit in case of a mistake?
