Hi Wil. I can't wait to see your yacht/sub. I'm very intrigued by the
concrete hull. What did you mean by ''whale like'' propulsion ? I have often
toyed with the idea of using fins or wings to propel a craft. I have some
sketches on the geometry of a ''tail'' fin and also wings like on a manta ray.
With a flexible rubber skin it may be possible to achieve a very ''fish-like''
mechanism. I wonder what the power requirements are like to get the same
propulsion as a prop. Anyway, I look forward to seeing your sub and wish you all
the best on your project. Frank D. |
