<DIV style="font-family:Arial, sans-serif; font-size:10pt;">Jon, I think you're better off dealing with the hyrdrodynamics of the hull shape and nose shape and sufficient propulsion rather than try to gain any small amount of drag reduction you would gain from getting the sub higher in the water . That said, the ww2 subs were able to go faster on the surface, but was that because they had the benefit of the powerful diesels on the surface? <DIV><BR></DIV><DIV>Brian</DIV><DIV><BR></DIV><DIV> <BR><BR>--- personal_submersibles@psubs.org wrote:<BR><BR>From: Jon Wallace via Personal_Submersibles <personal_submersibles@psubs.org><BR>To: Personal Submersibles General Discussion <personal_submersibles@psubs.org><BR>Subject: [PSUBS-MAILIST] Buoyancy dynamics<BR>Date: Sun, 16 Aug 2020 14:56:42 +0000 (UTC)<BR><BR><DIV style="font-family:times new roman, new york, times, serif;font-size:16px;"><DIV dir="ltr">Assuming perfect neutral buoyancy, how much MBT water displacement is needed to get a sub or particular size/weight moving topside at a reasonable speed?</DIV><DIV dir="ltr"><BR></DIV><DIV dir="ltr">Jon</DIV></DIV>_______________________________________________
