My winch is the same as that manual one pictured, and I've also just ordered a Winchmax 3000lb electric for the new trailer!
I've been using 6mm Dyneema for years on both this and the old boat, plenty strong enough for a boat winch and lasts much longer than the silly straps. I guess it cost me about £25 for the bit I got recently c/w a hook spliced on to it. I bought it from Goodwinch, a 4x4 winch supplier.
A Boat is a hole in the water, surrounded by fibreglass, into which you throw money...
