Re: [PSUBS-MAILIST] Reserved buoyancy

["Carsten Standfuss" <MerlinSub@t-online.de>]

Show us the general weight calculation of your boat here.. 

I estimate that : 

A.1) Estimate bouancy calculation : 

0,921 by 0,921 x 3,1415/4 x 2,3 m = 1,5323 m3 displacement in freshwater
(1,5706 in seawater) without endcaps and outside displacement parts. 

B.1) Estimate weight calculation : 

hmm...
Which tickness has the pipe ?  Mild steel or stainless ?

regards Carsten
