Harken main sheet traveler: exploded after sheeting in about 200 yrds off the beach. This was from a rear cross bar I got off the internet. The ends busted out. I think what caused the problem was a couple missing roller bearings or worn out bearings. Replacement is around $175 for the whole thing. Might be able to rebuild it cheaper. This "what did you break this weekend" is a post I want to do every week to learn about and how not to repeat breakin' sh#t. And I wish people will respond with more damage than I. (make me feel better thru your pain)
