originally i think the 5.2 only came with 1 trap for the crew like the tornado
but then about the late 70's keen cat sailors started moding their boats to dual trap.
attached pic shows a 5.2 with old dagger hold up system
basically you need a small eye on the hulls and then eyelets on the tramp for the helm bungee to go through
You don't really need the eye on the hulls, I just have the trampoline holes for my rear trap shock cord, I've never felt the need to migrate them so far out on the hulls.
