Thinking outside the box - the human powered semi-sub
I got an email the other day from Anthony Davis with an idea that I thought could have some merit. So, I decided to model it up quickly to see what it would look like.
Human Powered Semi-submersible
The idea is that the boat would be mostly submerged with the water line almost as high as the deck. The rounded top would be the only part of the boat that would be above the water line. A clear dome covers the pedalling station which would be completely water tight. Fresh air would have to be pumped into the boat from a snorkel or something.
I based the concept model from the existing model of Concept1, but I think it would be better to design a rounded hull (more submarine-like) than something that is more kayak shaped like what is shown.
There are probably too many cons for this concept to be considered safe for an ocean crossing. I think the existing idea behind my current design - Concept1 takes the pros of this idea and eliminates the cons. It's smooth, aerodynamic and covered for less drag through headwinds, and a dry cockpit during rough seas. Plus it's high enough above the water line to allow the canopy top to be opened during calm conditions, or to get out onto the top.

Concept 1 with the canopy top open. (Boy that water line still looks pretty high. I can see that the slightest wave would easily flood the cockpit. hmmm....
