Alternative Email

I have been hearing from several people that my email has been down, on and off, for several days. And still much email has also arrived. I looked into it and it was not the server being down again. Seems the Drizzle spam filter got out of control at the ISP. You’d think Seattle is a 5th world country. So, I just got an alternative email for those situations. themultihulldesigns@gmail.com
It seems some slacker already got the simply multihulldesigns. I will post on website as soon as I can.

Cat 2 Fold 30

Three years ago I designed what I thought was a simplification to Rafi’s Cat-2-Fold beams. To make it less costly, I chose off-the-shelf mast sections as the connective beams in place of carbon fiber laminations. Rafi thinks it won’t work. I think it

will. It has never been tried. I publish it here with the understanding that if it is published, someone somewhere else won’t be able to patent it and prevent me from using it. I can’t afford to patent it, and besides this market is just too small to make it worthwhile.
So, some of the snapshots. Ignore the unstayed mast bearings.
