The Dashew’s are justly famous for designing sailboats. Longtime sailors themselves, they have "been there and done that"… everywhere, it seems.
A few years back they decided to switch to power. Not content to go the normal way, they designed a craft from scratch.
Just incredible. A long, narrow beamed boat, with great economy and some different ideas for accommodations, equipment, systems, etc. Its all spelled out.
Read the web page… the detail is remarkable. Most of use will never own anything like this, but you will learn something.
Of course the rest of the site is worth checking for sail interests.
