Not sure if that's what it's called, BUT.... I need to put a hook on the back of my 1985 Bayliner o/b (Force 125) Is it hard to do? Where would I install it? It's got the outboard motor right in the middle so I can't put it in the middle. Is there a triangle rope deal I can buy so I can hook it up to where the boat straps go from the trailer(on each side, just underneath the water when boating) Anyone have any suggestions, thanks! I'll be pulling tubes and wakeboarders and skiiers (for weight issues)
