Jetpilot Flexi FenderJetpilot Flexi Fender The Flexi Fender is the docking protection fender for PWC the answer to dock rash and gel coat damage from bumps, scrapes, and rafting up contact.

The moulded acetyl hook grips under the rub rail without slipping, so the fender stays in position rather than drifting off
