I am making a boom for the ARC21. I need to figure out the gooseneck and out haul. Do any of you have a schematic that I can work from? Demensions I'll figure out, concept is what I need. Using Alu tube.

Outhaul diagram

You might also add a 3/8" bungee line to produce an "inhaul" force when you slacken the outhaul. If your boom attaches to the sail clew via a traveller car of some kind, you can run the bungee internal on the boom as well, with just a through deck block in the right place.

Otherwise in light air you won't get the best benefit from easing the outhaul.

Eric, How about some recent pics of the boat?

Otay!
