offtopic..but related. I am fixing up an old 5.2. You picture shows the setup for tensioning the daggerboards so they don't slide. Do you have a closer shot? all lines and bungie cords on my boat are rotted, and I don't know how to set up the daggerboard. My 5.2 is like yours..it has the aluminum pole down the center of the tramp.
Thanks,
Dave
