[PSUBS-MAILIST] John Gaetner's Wooden Submarine

["Captain Nemo" <vulcania@hawaii.rr.com>]

Hi John,

 

Without running the numbers: she looks like she can be made to balance, but if this is a dry sub, she'll displace a few tons.  Wood being relatively light and buoyant, there's a good chance the waterline will be so high your prop will chop air on the surface; and where's the weight required to submerge?  You could stuff her with lead, but that will take up a lot of space and could lead to a structural failure. 

 

It's a nice design.  Why not build it in steel?
