Dennis,
I have not been on here for a while (gone Jan 1 to May 15 in China, Australia, China, then Canada....too busy....but retiring on July 31!), but skimmed over this string just now and see your desire to to be able raise the amas on the BOSS outriggers higher off the water, like your adjustable Hobie set. The BOSS aka tubes are 1/16" wall, but I made mine out of 1/8" wall aluminum tube. Although I am a metgallurgist, I do not have experience cold forming aluminum tubing. I believe that it can be done on with the right type of tube bender. However, I think the simplest solution is to just raise the entire outrigger higher off the coaming. I have this provision in the BOSS set up that I made using just the BOSS amas that I bought from BSD. If you look at my Facebook album (
https://www.facebook.com/media/set/?set ... 916c13c1c4) about the 100th photo or so, you can see I have spacer nuts which I can move from the upper positon above the aka tubes, to the lower postion, below the tubes, to raise the aka higher off the coaming. I have never actually raised them very high, but if the stainless bolts in the coaming clamps are left long enough, like I made mine, it's very easy to do. If you want to raise them a lot, I think it would be wise to go with bigger diameter bolts.
I also just posted a new topic on the forum about the new 32 square foot genoa sail, that I designed with the sail maker at Sailrite, and finally got assembled and sewed up this last week. In the FB album that I sent the above link to, you will see the last 8 photos are of that genoa sail. I still need to sail with it. I'll post something after I try it.
