    Whew. Executive decision. The right one, I might add.

    Sean - you didn't address me, but I am guessing that your comments were directed at me. No offense was meant. In my line of work, which I don't think is unique, people ask for input on projects - both fair criticisms and thoughtful suggestions are equally helpful and welcome. Certainly I tried to give both, and if you count them, the suggestions far outnumber the criticisms. I don't know what your prior experience is, but frankly, if you're going to succeed at this, you're going to need to develop a thicker skin.

    That first site's boat has a good design idea. Mostly enclosed. (But for your adventure, a totally enclosed boat with hatches might be best.)

    One practical problem with being fully submerged is that you need to minimize the vessel's overall cross-section. A surface boat can be more roomy as long as windage isn't too big a problem. The submerged section of the boat is much smaller, the hull would have to be taller and narrower, and it might still be hard to sit upright in that space. A deep, narrow surface hull would be somewhat of a compromise, reducing wetted surface and wave drag much more simply.

    Quick question: Is increasing the boat's length (and decreasing weight in proportion) a possible way to increase speed?
