Re: [PSUBS-MAILIST] K350 Salvage concept...

[Jon Wallace <jonw@psubs.org>]

Hi Lawrie,

Don't forget to go back in to your account and check the "publish" box 
so that people can find them just by going to the projects page and 
looking up your name, rather than relying on the link.

Nice modeling work and detail.  Obviously viewing from the pilot seat is 
going to be limited on the sides, but perhaps that is ok if the conning 
tower is only going to be used for piloting.  I would remove the 
elevators which really are not necessary for a slow moving vehicle and 
should offer less obstruction for forward viewing from the pilot seat.

The pressure hull will require some hard ballast underneath to keep it 
upright on the surface in the event of an emergency release from the 
pod, otherwise the weight of the conning tower will cause the vessel to 
invert and entrap the occupants.
