Re: Ever use stretch dock line?
they work well for SOME situations, and horrible for others...
good: centering a boat in a slip, using two of them
bad: using them on a single side of the boat. What happens is they end up stretching out, and then pulling your boat into the dock with a decent amount of force. A rigid line just puts the stress into the dock and boat cleats, both generally more than capable of handling it.
I've got a couple, and I only use them as anchor leads or when tying off to a edge of a dock in current. (so the boat is free floating a couple feet downstream from the dock, no chance of hitting it because of current)
