We use a Whale below deck
foot pump with a simple whale spigot at the sink. If you have no through hull
for the saltwater, you'll have to add one. Any marine
pump should work
just fine, in any case.
If you are going pressure water
, don't get a faucet that is made from pot metal. Pot metal corrodes very quickly in a salt
. The guts of any faucet should be fine, however.
