That is false.

Stainless steel suffers galvanic corrosion so easily in salt water that
it isn't allowed to be used below the waterline on most types of
oceangoing ship hulls.

Strange. I lived on a auxiliary powered sail boat for about 15 years
and was never aware that stainless wasn't to be used on a boat....


Not a boat, a ship.
And not the whole ship, just the submerged part of the hull.

Most enclosed-hull boats I've seen had all kinds of stainless deck
fittings and railings. Those are safer to fail and easier to fix than
the underside of a 200,000 ton bulk carrier ship tho.
