[PSUBS-MAILIST] How heavy can I go?



Dear Shipmates –

I am rebuilding the modified ambient sport sub (www.ivccorp.com)  with a top hatch.

I want to seal off the back swim-in area and make the cabin area dry.

 

My question is:

How do I calculate the weight allowable for the sub

which will allow it to sink when the ballast is blown and more importantly,

Re-surface when the ballast is re-filled?

 

Thanks –

Greg
