Vintagereplica:
There is an old thread showing all my mods. The Ultimate Tandem Island (Hydrofoils, Spinnaker, jib, etc (
viewtopic.php?f=69&t=33720 ).
I went into great detail about all the designs, and there are many pics of my setup, and I go into great detail about each part of the design. I started with the 90 sq ft main sail, a 40 sq ft jib, and a 135 sq ft assemetric spinnaker (G2). Later on I cut the jib back to around 30 sq ft because the bigger jib was too much for the original twist and stow rudder. Recently the old jib which had around 2500 sailing miles on it finally wore out so I am using just a 22 sq ft standard hobie kayak sail until I get the new jib made, the new jib will be a 30 sq ft furlable wing sail, that I'm designing right now.
Captchaos ( Jim) lives near me, we go out together sometimes, he has sailed my setup. All my sails are furlable, and the boat is rigged to run single handed (solo).
I haven't made any changes at all in a very long time I use the boat most every weekend (weather permitting). The only additional changes I have planned are to convert all the sails to wing sails, and maybe add HAKAS.
If you have any further questions feel free to ask.
