Is saltwater good for houseboat?

Can you put any houseboat in saltwater, and if so, what prep do you have to do, and approx what cost on a 16 x 75 foot house boat?

Thanks for any help, John

Good question John, generally you would apply a anti-fouling paint on the hull, and the cost varies according to the anti-fouling paint used. Your best best would be to contact a local marina shipyard in your area.

Many people will flush the engine(s) with fresh water after a run (not necessary if your engine(s) are prestone cooled).

Saltwater is a good conductor, so you would make sure your anodes are in good shape, and an extra option would be a galvanic isolator to reduce electrolytic corrosion.

Hope this all helps, IAN from

Salt water
by: Amsterdamhouseboats

Different anodes are required for salt water.

Incorrectly sourced through hulls that were no problem in fresh water can be a big problem in salt.

I'd get a good technician to go over your boat and check these and many other details, especially if your boat is aluminum.

Salt water is completely different stuff.
