How easy do hulls get hooked? Can it be done easily or does the boat need to be dealt some serious abuse?

Sittting it on a roller trailer before the resin is fully cured will do it. Although polyester resins are supposed to be thermosetting, some are also a bit thermoplastic. Strapping a boat down to the trailer really hard and leaving it there through hot weather may also do it.

Some boats are built like this to keep the bow down.

Thanks JW

If you mean boat on trailer, yeh, could do, if the moulding/materials are crap.

I once built a slalom canoe from materials sourced from the local laminators. When it was strapped to the roof rack, and the sun was shining, the ropes left grooves in the deck! A hot air gun removed them! Very thermoplastic - with a memory, like acrylic.

Didn't buy from him again.

Brilliant, a canoe with a stepped hull, should have really shifted

Surely the problem with the boat is 150 kg of GRP cuddy on the front of a 5.8m hull, ie a short one. Think Cookes idea of moving things aft makes sence.

jwalker is absolutely right. The point is that when you look along the keel of the boat you can pick up even the slightest deviation but I believe that it has to be pretty bad before it affects the handling.
