That way, the forward viewport could be incorporated into the hatch and the hatch/ port could be in the "up" position to get in and out and then in the "down" position during the dive for viewing. All internal components could be mounted on an internal frame that hangs from a bearing so that the pilot is always upright. The main ballast system could be a pair of port/ starboard pontoons.</div><div id="yiv5207524531yui_3_16_0_ym19_1_1499629315211_3150"><br clear="none"></div><div id="yiv5207524531yui_3_16_0_ym19_1_1499629315211_3150">For a shallow diving sub, the hatch/ port could be a large dome for good viewing. A self draining "sail" could also be added around the hatch/ port.
