Richard:

The "venturi effect" (named after the Italian physicist Giovanni
Battista Venturi), is the phenomena that leads to an increase in
pressure when a fluid or air flows through a tube or pipe or other
media that contains a constriction. Rapids through the narrow area of
a river, or high winds through a mountain pass are examples of this
effect. Any faucet designed for the RV market should be a good
alternative, provided they are made to stand up to a marine
environment (most are plastic).
