First thing I noticed in all the pix was the bad wrinkles in the mainsails.., not enough downhaul.., even when sailing off the wind when you cannot be oversheeting.

Also, I was privileged to sail on an outrigger in Saipan. It was sailed by real natives with all the parts tied on with local woven weed. It was quite an experience.
And in tacking it did the same thing that you have described. But, it was a very, very slow procedure.

How can you swap ends with the rudder that quick and claim it will tack with modern beach cats?
Just curious,
Rick
