I'm wondering why a "6-pack" OUPV license (for which you need only a year's time of 8-hour days) wouldn't serve your purpose while you continue to get the rest of your time for an "inspected vessel" license such as the 50 or 100-ton Master of auxiliary sail (and steam and motor).
And if you're going to carry more than 6 paying passengers, you will also need to be doing it on a Coast Guard-inspected vessel, meaning a lot of design and building requirements (under 46CFR subchapter "T") which your dream catamaran may not have.
Counting time? I had to add in the rowing time going out to the mooring and back to get enough, but they accepted it. This was 30-odd years ago, though.
