Nylon is the material of choice for docklines, because the stretchiness it has cushions the shock(s) of waves against the boat and dock. That's why your anchor line is probably nylon as well. (Though in the Med, people tend to like chain better.) Braid was developed partly in order to reduce stretch, so...3-strand or other twisted line would seem to be indicated. For a boat as big (and HEAVY) as yours, 1" nylon docklines (25mm) might be a bit light. 30mm or more might be better. Even if the bigger stuff is overkill on the strength end of the equation, it gives you a safety margin in the inevitable event of chafe, so you won't have to replace it for a longer time.
