I tend to do this - I'll be somewhere and all of a sudden I'll get hit with a new idea like a bolt of lightning. I've learned to make scetches now so I don't forget.

I was looking for ways to increase the speed, and retail the release of the stern at the same time with the Fish, and also increase bounce from a back surf dramatically, and after about a 6hr flight on Air France, I had it and did the first scetches.

The seat: I wanted to replace the "lap belt" with something just as effective but safer, and also I was looking for a way to put the entire system on the seat so it'd all move as a unit.

Anyway, for your viewing, here is a scan of the drawing, done on the back side of a vomit bag!
