Collin, isn’t that what the trailer’s suspension is supposed to take care of?
If the trailer is sufficiently suspended and dampened, the boat should not rock about in its cradle and the straps don’t need to be of rubber.
Maybe I’ve got it wrong but the rubber in the hub acts as a spring only, it does *not* act as a shock absorber, isn’t it? I wander if a set of shock absorbers would do any good? If only there would be a way to mount those buggers.
For the time being I’ll stick to carefull and slow driving and avoid back roads when posible.
