Fleet 42 sails in the Sea of Cortez frequently. One of our members shows up with his P19 down from Utah. He covers 3 or 4 feet of the nose of his P19 with the slickest set of stretch covers I ever saw. Looks like neoprene. Peels off, offers great protection. Sorry I don't know where to get them. I'll try to track him down.

They wouldn't have protected my boat from the debris my RV kicked up when the tire blew. The exhaust clamp hit the front crossbeam hard enough to put a dent 2 inches tall by 3/4 inches deep. Had it hit the hull, it would have made a hole at least 5 X 3.

Other than that, I've never seen much damage from debris.
Cheers.
