Sorry about that, I'm not a particularly good writer, I realize that

Actually I was working on a Motor/Sailer design back in '89,'90 when Lock Crowther was begining work on the TaraVana design. That prompted me to consider a little more engine power and that older mainsail-less rig design of mine.

The key word was NO Mainsail. As I point out on my website, "I'm well aware that once a large gamefish is hooked, the vessel must get rid of all sail quickly, with minimum effort, and get under power."

To sail this rig in 15 to 20 in any direction the loading on the mast base and back stays must be off the planet. I can only imagine that if the rig stayed together then the hulls and or cross beams must bend and twist like crazy. Even on a conventional rig this can be a major issue.
Can't get into defending the rig design at this time, nor on this forum. If you care to look at the aerodynamics of the situation and some of the loading discussions I can point you to numerous discussions on another forum

Interesting that you bring this 'free standing' subject up right now. Wait a few weeks and I will surprise you with a new design I'm working on right now I promise you will find it very interesting.

In the meantime did you notice this free-standing ketch referenced above in posting #32. Opps,the link was wrong, here is new one, http://www.hybridfishingboat.org
