Did they really make a difference? Do you notice any increased tendency of
the boat to shift during towing, compared with having only carpet on the
bunks?

We have a wood hull, not fiberglass. Bunks were carpeted and was too much
friction.
Bought the spray bunker stuff from West Marine. I think it's called "liquid
rollers" or
something like that. It works REALLY WELL. Be careful you don't put on more
than
you want. I like it because you can add just enough, it's very easy, and the
bunks are
still carptet, not plastic.
