Upgraded to a 1977 Ericson 27. Used it for 27 seasons... went from 0 kids to 3 kids and back to 0 kids. Logged 7291nm (actual miles were further - the knotmeter broke a few times).
The need for more creature comforts, including a bigger V berth, was gently impressed on me.
Upgraded to a 1989 Ericson 32-3; keep wondering why we didn't do it 10 years ago. Oh yeah, tuition. :-/
