Our 1986 Montgomery 15 came to us on a Trail-Rite trailer. The boat is secured to the trailer with the winch strap at the front and a long strap made from what seems to be seat belt material that goes from the back corners of the trailer up over the boat. The strap attaches to the trailer with hooks sewn onto the strap and is tensioned in the middle with a metal "buckle". The buckle allows the strap to be adjusted to about the right length and then tensions the strap my flipping over with a lever. The strap is starting to cut through where it goes over the wrinkles on the side of the boat. I'd like to get the very same thing to buy new because it works well, but am not having luck with online searches. There are too many similar things and have no idea the best terminology to use in my searches. I could just get new seat belt strap material and use the old buckle and hooks, but don't have a good way to sew the hooks on to it. Does anyone know where I could get a whole new strap with hooks and "buckle"? Thanks! David GrahBishop California
