Re: You know it is a bad day when:
Straps are fabric, they ROT!!!
Switch to the cable a bigger one than you think you need.
Most only use 2 maybe 4 feet of it anyway.
The roller trailers do exactly what their supposed to, they let the boat roll off onto the ground

Safety chain always.
My bunk trailer won't let it slip off.
I can drive down the road with no straps or chains(don't do it but I could) not with a roller trailer.
Be courteous and get your boat ready in the boat prep area(most ramps have one) I get ready at home, then all I have to do is unhook the cable and safety chain and back it in.
