Re: [PSUBS-MAILIST] FW: sub ops
Dean - check your email settings. Your messages are showing up in a
huge font on my system.
As for your comments - I'm sure every designer has their reasons for
keeping their designs as light as possible, but it is an interesting
thought exercise to consider the actual downsides to incorporating
larger main buoyancy tank volumes, in conjunction with additional lead
ballast, to increase the righting arm of any given boat for the same
freeboard. Lead is relatively cheap, and exterior MBTs would seem to be
one of the easiest structural / mechanical retrofits that can be
effected. The obvious downside being the necessary power to drive the
boat at the same speed, but for most PSub applications (Cliff excepted),
we're not racing around down there. Perhaps designing for sufficient
stability to support a load on the weather deck is worth the additional
displacement? Even without changing displacement and ballast, it might
be possible to lower the position of fixed ballast on a given design in
order to increase stability? I am curious to know if anyone on the list
has, after completing and testing a sub, opted to make modifications in
order to change the stability. Comments?
