can anyone explain how the centerboatd control lines are routed on 3386 as shown in this image. Rather than the winder system the board looks to have only one up and one down purchase, rather than purchases on each side. If this is the case - when you pull either up or down - i cant see where the fixed end of the purchase might be. Any clues?
No idea, but at one time the OK solution was:

The system on 3386 was one that I had on various Solos and Phantom. One rope for up, one for down. The four dead ends are terminated at the thwart with elastic take ups for the slack. The uphaul went through an eye in the thwart (knot on the reverse to stop it going through), then inboard to the case, along the side and then up through the case top, round the block lashed to the board head, then down the other side. The downlaul is the reverse. To raise the board, a pull on the uphaul first takes up the slack against the elastic until the unpulled side runs to its stop. It is a bit agricultural and only gives a 2:1 purchase. The system on BAU and the Winders is a 4:1 both ways and is easier to move, although with twice the string to pull.
