I second the Uniflite , a genuine glass boat with none of the TT Chinese Composite horrors.
The usual gas engines are actually a big plus as under 200-300 hours a year they cost far less to maintain and repair. No problems at Trawler Crawler 6K either.1/4 the price of diesel to replace.
Go visit a bunch of boats to see what makes you most comfortable.
On most sail boats below is the living area , power its mostly living at deck level or above.
Even tho the inside view is better on the water do not omit or skimp a cockpit .
20 ft in the air in an oxygen tent is NOT the same as sitting at water level in a cockpit.
And remember KISS , if its not on board , it wont kill the batts , need repair , parts, replacement , or upgrading.
Or take up space.
