[PSUBS-MAILIST] Stability & Buoyancy

[Joe Perkel]

Marc's comment about the low pressure blow is worth taking note for those looking to build in massive reserve buoyancy. Those Fleet boats had a 600 lb HP manifold and a 10 lb blower manifold purged the tanks once surfaced. Of course were talking about tons of water per tank. The trade offs for us to contend with are HP air, and battery consumption, but one could install a small dedicated compressor to purge the tanks once your snorkel (air induction mast) was above water.<br/><br/>Incidentally, reserve buoyancy defined as that which is above the waterline. Such buoyancy comes into play for walking on deck and more importantly to oppose / resist heave.<br/><br/>Joe<a href="http://overview.mail.yahoo.com?.src=iOS"><br/><br/>Sent from Yahoo Mail for iPad</a>
