Frugal and Energy Efficient Living

It is very possible to use a boat to reduce your environmental footprint.

It is common to generate all your own electricity, some (if not all) of your potable water and seafood for much of your protein.

It is also possible to use electricity for auxiliary propulsion on a sailboat, but that generally requires shore power for charging.

Because space is at a premium on a boat, you will still need inputs of vegetables and starch, and you will still generate waste (albeit a fraction of that which one generates on land).

There are waste disposal devices which can treat sewage before it is discharged overboard, but it is generally better to empty the waste tanks at a dockside pumpout station and let a large onshore treatment plant deal with it.
