Congrats on your new boat, and welcome to the forum.
We were faced with a similar consideration last year with our forward head
. [1 of 2]
Instead if increasing the amount of human effluvia we were carrying with us, we decided to replace a perfectly good Lavac
toilet with a Nature's Head
We couldn't be happier, and even our guests choose it over the 2nd Lavac
'...because they don't have to pump...'
We kept the smaller holding tank to use as the liquid receptacle for the Nature's Head. [You can plumb the liquid side to a tank instead of using the built-in bottle.] Your 13 gallon tank will go a lot further this way...
You will find many discussions on this forum regarding same, and it is not my intension to change your thread into a composting head discussion, but rather introduce thoughts about another option.
If you feel this is worth evaluating, then check out the 3 main players in this market: [for boats] Nature's Head, Air Head, and C Head.
Here is my blog post
with many more details [because we are asked about this so often...] in case you are interested in exploring further.
Just another way of looking at things...
Best wishes with your new boat!
