Poop: Follow same method as above. HOWEVER, add one extra step; before going, be sure to pour a cup of water into the bowl. If necessary, swirl a second cup through the bowl after going.

Using this manner, 3-4 adult males can make a ~25 gallon tank last the better part of a week. When tied up in the evenings, use shore facilities. While at sea, guys can pee off the back of the boat.
While this method will conserve capacity, it also leaves waste in the hoses, which is the number one cause of odor. If your waste lines rise from the head to a vented loop and then return down to the holding tank, it takes a good gallon of clean chase water to flush them out.

I have no problem with peeing over the side in open water, but it is technically a violation of discharge laws and there have been people cited, if witnessed doing so.

Runs contrary to everything I've ever read. You are not allowed to discharge waste from any equipment on the boat, or any part of the boat, but AFAIK an animal, human or otherwise, is still allowed to pollute the waters directly.
Pee in a cup and dump it, that's a violation. Pee without the cup, no violation of sanitary or pollution or dumping laws. Local laws about public urination or indecent exposure, are a whole other issue. (Political comment deleted by tdw) . (VBG)

I have often heard this but have a hard time believing it. They could get you for urinating in public (a misdemeanor in many locals) or indecent exposure.

"I have often heard this but have a hard time believing it."
Heard what, (Off Topic comment deleted)

What's so hard to believe? Most regulations are poorly written and focused on one point. Regulations concerning the discharges from a vessel, are written to regulate the discharges from the vessel and the equipment on the vessel. The souls on board are part of neither, under the laws.

In fact, from the objective viewpoint of a topologist, a sailboat is very much like a donut. It is simply a torus (as the donut) but with multiple holes in it. Two-hole torus, three-hole torus...Still a torus. Now, apply that logically to the regulations, and you can have and use all kinds of aperatures "on" the boat, because if they penetrate the hull, they are not on the boat. They are simply more holes in the torus, and you are still on the outside of the torus, outside of the vessel, even if are belowdeck and pee through a urinal fitting. That's not "on" the boat, that's still on the outside of the torus.

As to the regulations...check the CFR. Its in their somewhere. No mention of toruses (tori?) though.

Re: How big a holding tank vs. camping

I posted earlier about the urinating issue if it goes into a comode it must be retained inland any other device as well as peeing over he side comes under the direct discharge exception as I referenced in post 27 of this thread
