They could go outside on a peg so to speak. The only problem is you want them at the bottom of the sub. That means hauling the sub unless you want to get wet. Maybe a slide system. I thought the same thing to put the air outside, that would kill my sleek and slippery-ness. :-) </SPAN></div>

<DIV>Hatch closure from both sides deffenetly a good one. I would say adjustable exterior weights. I hate the idea on chucking weights on the floor and then sitting on them. I am torn between that and moving the hp air tanks to the exterior to allow alot more room on the inside.</DIV>
