The preference for 1 head is certainly not mandatory, it was just based off my experience growing up aboard a Kadey-Krogen 42. We only had one head and even with 5 or 6 people on board, we made it work without much fuss. I do agree a second head would be nice when company is aboard, but not necessarily at the sacrifice of more utilized space for 95% of the year when it's just me and my dog. At least that was my rationale!
Fully understand your rational...
Back in the 1950's, 60's on NE coast black tanks in private pleasure boats were seldom encountered... took care of decision on container size for that crap - LOL! And, my family of 5, along with most other families of the time had only one head per boat. Showers were seldom included, swimming with bar-soap worked well. But - that really is pretty darn old school... accounting for nearly 3/4 of a century ago... i.e., back in the middle of last
Think of the difference of boats in 1950's / 60's compared to boats in 1870's / 80's. Well... there's the answer - now, what's the question??
