Re: [PSUBS-MAILIST] Nemo's Nautilus
Hello Joe
The Ictineo was a wonderfull submarine made of wood.
There were two models the Ictineo one that used
manpower for propulsion and the Ictineo 2 that used
steam for propulsion. In the book Monturiols dream
you get a nice idea of this ship. Monturiol also
wrote a whole book named El arte de la navegacion
submarine "the art of submarine navegation" is in
spanish and here he explains all the gadgets he used
in his sub. Very interesting stuff. As far as I know
he went down to 40 m with his sub. Very deep for
1864.
Unfortunately he had to sell the sub as scrab to pay
his debts.
Best wishes
Jürgen
