Jim-
Mary was asking about a Taipan 4.9 and there are "pullup" lines on the boards from the factory w/ the lines integral in the board "cutout" as you describe (see attachment). It is a fairly simple matter to rig a "pulldown" line to the Taipan (and Auscat's they are modeled after) boards by adding a second set of eyes (or standup blocks if you wanted to get fancy) next tot he standard "pullup" eyes with a line from the top of the board "handle", through the eye and across tramp to other board. Line lengths are set so when board is up/down the line you would want to pull is fairly snug across the tramp and a simple tug up, back or forward will raise/lower both boards simultaneously. Very handy on solo boats!
