I don't think anybody's being too nasty... but sailingdog had a good point, let me rephrase: boats are each designed for a different job, some features overlap, some do not, a boat that does everything
is wasting its capabilities (and money spent on it) unless it is actually doing
everything. The Coast Guard (All Praise be Unto Them) actually need that capability, very few others need more than half your list to do everything they need or want to do, and do it safely. If you're looking to design the next great rescue boat, more power to you (and make sure Tartan gets his cut!), if you're looking to make a marketable addition to the 'boat candystore', think it through a bit more (esp. 'target customers').
And while you're designing boats, i'm looking for a good one for a New Haven Sharpie about 15-17 ft, centerboard (or twin keels if you're up for a challenge) and traditional cat-ketch rig (or is it a 'schooner'?)
