Excuse my lack of terminology but I have a 1981 Venture 25. The owner before me installed a "traveller" that controled the boom tension etc. I see from pictures that the original set up is from the aft end of the boom, which i would prefer to clear the floor space of this other device. Can someone tell me how the rope/pulley (vang i think?) attaches to the boom at the end? Any photos available? Thank you.
