Winch strap replacement?

[tglee]

After 15 years I think it is probably time to replace the winch strap on my trailer. I see that they are available with a “loop end”, “tail end” and “cut end”. Does anyone know what I need for my Escort trailer? Also, what is the appropriate length for an 18 foot boat?

Apparently I need a 20 foot long strap with a loop end. I unwound the whole thing and measured it.
