I have had dyneema on my previous and current trailers, also would never consider using a stupid poly strap again. I have 6mm Dyneema from Goodwinch, after using it for a few years on the winch on my Land Rover (10mm rope on a 10,500lb hydraulic winch) and being totally converted, would not go back to wire rope either. The rope 'fluffs' a bit on the surface with lots of rubbing wear, but the only real danger to it is loading it where it runs over a very sharp edge, which is unlikely in a boat winch situation. Use on a boat trailer winch is the same as a vehicle winch, you need to make sure the bottom layers on the drum are tight or it will pull down through and potentially be hard to get off, but in a boat loading situation you will almost always winch on from a near empty drum under the max load anyway - I have never had a problem with mine. Brilliant stuff.
A Boat is a hole in the water, surrounded by fibreglass, into which you throw money...
