Merry Christmas

Those old windsurfers rocks! Here's me and my brothers using our combined strength on those old super heavy rigs. That old board kept us going for a decade.
You can't really go too far wrong rigging up that old equipment. Just Like I mentioned in another recent post, those old booms have a habit of wobbling. To make sure the boom is attached tightly to the mast, have the boom lay flat against the mast (not at right angles, which it will be when completely rigged), then tie the boom to the mast. As you then pull the boom out at 90 degrees to the mast you notice how tight it goes. You can still sail with a wobbly boom but it gets annoying.
Like someone else said, don't be any hurry to learn to waterstart. I spent a whole summer at age 15 teaching myself. I have never sworn so much in my life.
Keep having fun.
