Suprisingly, GRP does pretty well as long as there is no pounding or twisting.The part about "pull the boat off the ROCKS" made me cringe. It's mostly sand and mud in these parts (NC). Ugh.
It says the boat was caught by winds and pushed there. Interesting. It looks like a nice boat, but pretty wind hog-ish. I won't forget this when I'm cruising that area, probably next year.
