Thanks for the responses. Just outside of buzzards Bay is beyond the no discharge zone. I've sailed out there quite a few times on nice breezy days. It would only be a 30-40 minute sail on a good day if I really needed to dump some poo...
what is a reasonable sized holding tank. I really don't want to be carrying around too much of that stuff. I see new 40ish foot boats with 20 gal holding tanks... I don't know what that bladder I have now holds but, I doubt it is more than 15 gallons. In our harbor the Harbor master will put you on a schedule and you can notify that you need a pumpout by placing blue tape on your pumpout fitting. So I really would never need more than a week's worth of holding.

Date: Mon, 21 Oct 2013 14:53:42 -0400 Danny, Waste thoughts: Head up then down (loop hose) into holding tank - don't want the whole load set up to back siphon against that measly joker valve (buy a spare, change often) Holding tank exit to y valve then either up and out to pumpout or via a macerator pump through hull overboard. While you can put y valve on the other side that doesn't give you a way to dump the tank without a pumpout. Sure you can discharge directly but even in an area that allows discharge it is certainly not polite to do so in the anchorage/marina. Gravity as a way to dump is over rated- you want the tank low to keep the weight down which means whatever portion of the tank is below the water line is not going anywhere without help. On my 35-3 waste tank is under v-berth and y valve and macerator pump are mounted to the underside of v-berth getting them above waterline (make sure macerator pump can 'run dry').
