RE: What to do when she sinks...?
I swam because it was so close to shore.. I have a ski boat but it just wasn't worth getting it underway to go 40' into the water. Besides my friends and I are all very accomplished swimmers and we were all on a team together (years ago) and swim the lake on a regular basis. A real non issue but you would have had to have been there.... I had just crawled out of the water a few minutes before because the group wanted one more encore flight. I would probably use the boat if it were more than 100' or was moving away because of wind or current.
In any case the plane is all but repaired. I really just slapped the floats on for the weekend and neglected to make it a true float plane by sealing all the holes. The holes are now sealed and the wing saddle is now water resistant to some degree, and I have re-enforced the mount points to make them sea worthy.. I don't thing they will fall of so easily next time.
The lake is a private resort owned by the property owners and we all use it mainly for wakeboarding/waterskiing. In the morning it is all but empty and a really great place to fly. I have never flown off water before that day- but I often thought about it. In the future you can bet I will be bringing one more or more float planes for the weekend. What fun....
