Agree with the general consensus here regarding size for a family of three as well as your talking about two projects: restoration refit and a cruising adventure.
I’ve been inspired a few nice examples of older classic trawlers going through a modernization. Refit. Most of these are focused on cosmetics and the modernization of appliances, systems, etc.
It does go to show how you can bring an older vessel up to current design and lifestyle standards.

A terrific Kadey Krogen refit

We’re on a similar journey with our Kadey Krogen 54 while living aboard.
I’ll just say everything takes longer and costs more than planned but we’re able to tackle projects in chunks that keep us cruising.
