I bought a 24ft pontoon this spring. Haven’t had a lot of time to try it out. It came with a Hoosier classic trailer. This type of trailer has a pulley system to lower and raise the boat . It also has a safety cable hooked on a back but not connect to the pulley system. My question is this : when we towed the boat and originally lowered the boat in the water the safety cable was tight . I am unable to get the safety cable tight when I have the boat back on and secure . Is anyone familiar with this type of trailer
