Never finished it though. I agree of course with your thoughts about quality and serviceability, but I don't equate heavy construction with high quality. As a multihulls guy, I view light weight with quality as a desired performance engineering accomplishment, even in a monohull and even in a power boat. I also view narrow beam as a performance asset, whether sail or power, displacement or planing hull.

Here's my (unfinished) list:

pilot house or all weather enclosure to extend seasons
air conditioning and heat
generator
Solar panels
live-aboard room
Max 40 feet
Good light air sailing performance
quiet motoring at 7.5kt
Dinghy Davits or hoist to deck
Anchor windlass with helm controls
Bow thruster
Stern thruster or rudder close behind prop
Looks good
Diesel power
Protected running gear
