Some pictures of the Wet sub SVV (Shark Visitor Vehicle) 
a two man scuba divers wet boat I just design for the 
www.sharkproject.org to visit and film the white sharks 
in open waters.. 

Will be driven by three Minn Kotas dry ambient. 
Two Battery tanks 1 atm. 
Hard tanks via scuba regulator up to 12 atm. 
Boat from seawater resistans aluminium, tanks 
from stainless steel with bolted aluminium endcaps. 
Pressure air storage tanks from carbon fibre. 

My third boat..
