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

    You saved a ton of weight and drag.

    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.)

    Dual rudders, hm. That's an idea.

    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?
