anything on this in Skene's or nor do I recall seeing the info in any
other design books from the public library. Thanks.


Waste and water weigh the same amount: 8.333 lbs/gallon. There are 231
cu inches in a gallon...so how much it weighs and how much room it takes
up on a boat depends on the size of the tank it's stored in.

Add the weight of the tank itself and 10% to the volume of the waste to
arrive actual weight size of the tank.

On average, adults use the toilet 5x/day...average output (including
solids) per use: 6-8 liquid oz. Volume of flush water can vary from a
quart or so to 1-2 gal/flush, depending on the type of toilet and user's
flushing skills.

So you can save a lot of volume by peeing straight overboard. Just watch the
wind!

Yes, but I think there are some statistics kept on how many MOB drowning
victims are found with their fly open. :-)

William,

You can save water by peeing into the toilet tank.

Regards, Ron

You can save water by peeing into the toilet tank.

The lee rail is a lot easier, and using it is also legal.

I knew a young part owner of a C&C 25 who was so nervous or excited or
something when out sailing his part of the boat that he would be at the
lee rail every 10-15 minutes or so. Used to amuse the girls he took out
sailing but didn't deter them at all. He worked with computers which
might account for the restlessness.

I'll design a pee pulpit into this boat.

I guess, if I could squeeze in beside the sink and stand on a telephone
book. Sounds like good training for small boat cruising.
