I know of a fairly new glass/kevlar composite boat that was split down the centerline by tight rack straps.

: And I don't know why. I can't tighten up the ropes as much with a plastic or
: glass boat; they either deform too much or make those awfull cracking
: noises. My S&G is much stiffer than either. I can crank down as tight as I
: want.

: Maybe some wooden boat builders let them fly off as experiments? Some
: builders SO's don't want them building a new boat while the last one is
: still good. Hmmmm.
