ZM, don't take these guys too seriously, your opening question was a little vague.
You have asked some good ones now, I'm sure you'll get some good answers.
The Coast Guard does have some boats that meet all the criteria you've laid out, but I don't know where you could find design plans. I've seen them at work(play) out of Morro Bay. Some of the things they do would scare the sh---poop out af anybody.
Where are we going, and why am I in this handbasket?
