Re: How big a holding tank vs. camping
Since that makes for a stinky boat we have a different rule. If you are a boy and aren't in a marina then you pee over the side (legal, even though bucket and chuck it is not).
A 20 gallon tank lasts 5-7 days of cruising for us, a sample size of one couple.
So call it 20 gallons for 2 people for 6 days = 1.666 gallons/person/day, utilizing the male-over-the-rail conservation technique. This seems in line with CruisingDad's 2 gallon average.
