Can you use regular toilet on a boat?

That's because while your home toilet empties into a 4” wide drain, marine toilets plumbing is only 1½” wide. Given those dimensions, any inorganic material flushed down the drain will quickly create blockages that can seriously damage the pump or even crack the porcelain throne.

How do people on boats go to the bathroom? Bigger boats have toilets and some have showers. Smaller boats, you go over the side. I kayak regularly, a sit in type, and can't go over the side, so I use a large bottle to handle that need.

Sea or river water is full of living organisms, like, algae, plankton, microscopic bacteria, etc. When these organisms go into the inlet pipe of a marine toilet they're starved of oxygen and light, so they die and decompose. That's the smell!
