I found the website of the really great marine head installed on a
racing trimaran that's visiting Charleston this week.

You actually found the website for the US distributor. Lavac marine
toilets are made by Blakes a UK mfr whose marine toilets are considered
the best in the world: http://www.blakes-lavac-taylors.co.uk/index.htm

The Lavac has long been a favorite of live-aboard blue water cruisers
for decades...and In the days when most of the people here were
live-aboard cruisers, you'd prob'ly have been the last person here to
discover it. The Lavac has never become very popular in the US among
"weekend warriors" for two reasons: very limited parts availability and
price--$350-$400 depending on the rate of exchange...plus, it's a bit
intimidating to small children and landlubber guests compared ot pumping
a piston-cylinder pump.
