Channel Islands Surfboards, the S.B.-based surfboard manufacturing titan, has requested that a lawsuit it was hit with last summer be vetted in court. Back in August, Tom Gregg filed suit claiming that one of the company’s boards and the fins on it were dangerously defective after a wipeout left him with a wicked wound on his lower right leg two years ago. The injuries, presumably caused by the fins, included allegedly permanent damage to his leg’s tendons, muscles, and nerves. The lawsuit, which also names fin manufacturer FCS, seeks medical care, lost earnings, and the proverbial general compensation. Given the nature of the suit, and the fact that the mere act of wave-riding has built-in risks, the surfboard maker is demanding the issue be brought to jury trial.
