Mako:

I have the stock Hobie furl. Hobie Super H-17 system bottom of page. http://www.murrays.com/archive/41.pdf Don't know if it would fit between your hulls. The system work like this:

http://www.thebeachcats.com/modules.php?...=view_album.php

Line tied from ----------- block w becket ------------
furler and run -----------
thru block and back
and tied to bridle

With the sail unfurled. You take the furler line and run it thru the block and back to the bridle and tie it off. Then tie a 1/4 or so line to the becket and run it thru a cleat on the crossbar. For every foot you pull the sail will furl two. Makes it easy on the beach and between race or to depower.

Hope this help,

Doug
