Safely and securely trailer your boat with our boat cover tie down kit! Covers are trailerable in most materials, including Sun-DURA and Sunbrella. Our straps are constructed of 1" black polypropylene webbing, with convenient quick release buckles. These straps do not stretch like bungee cords, so the cover will stay in place in heavy winds and during trailering. Boats over 21' long, will require an additional tie down kit. One tie down kit includes 12 straps. They are each 12' long and can be shortened if necessary.
