Looking for some input on this one. Just picked up an older 18' cat and other than some beach rub on the bottom of the hulls she is in great shape. She is not even rigged right now so I will be able to turn her upside down fairly easily and get the boat on some foam or cushions to sit for a while. What has everyone had the most success with for the rub lines. We are talking about 2'-3' sections of the bottom of the hull being worn down to bare fiberglass. I was thinking of using 4"-6" wide tape fiberglass cloth or even springing for the kevlar cloth for a little upgraded rub resistance. Any thoughts from you guys and ladies out there who have done this already?
