I Can't take a well-tanned person seriously. <Cleveland Amory>
Twin keelers are very common on the East coast of the UK, where they are moored in tidal estuaries. The advantage is that they dry out sitting upright - much more comfortable for anybody sleeping aboard!
They tend to be a little slower and make more leeway than their fin-keeled counterparts, but they're a good compromise in the water's for which they are designed.
Leeboarders meet the same requirements, but in a different way and with added complications, though arguably with better performance.

Years ago my father had a twin-keel English Westerly (26' Windrush, if I recall
correctly). The iron keels were built like tanks, we slammed into a rock under full power
once with zero effect (after careful inspection in/out). ZERO! Massive keel bolts, no
question it could be trailered easily on a flatbed. The guy who later bought it, in fact, had
her shipped that way up to Maine from Long Island NY.
The boat wasn't a speed demon, but I doubt that's just the twin keels' fault. Great for
areas (like Maine) with extreme tides, I assume...

I apologize if I insulted your former boat. Windward is the biggest trade-off
of all.
The most beautiful ships I have been on seemed to stop at a standstill going
upwind.
And fin keels are almost like cheating, they are hardly keels at all but more
like airplane wings.

I am getting recall on a 20 or so foot sloop I in a yard on the way to Riis
Park from Brooklyn, and also for sale in Nanatucket in the MAIB mag.
Its a chunky little thing, w/ a miserable topside, but the twin keels were
intriguing to me.
Thats near Marine Park, home turf of the Brooklyn Mafia, where price gouging is
normal. So I passed, but now that tough times have fallen the gangsters, maybe
they'll dicker.
Actually.. they seem to be doing pretty well, things must be back to normal.

One of the touted advantages of twin keels is that the draft is
greater when the boat is heeled. So if you hit the bottom while
sailing, the boat stops, rights itself and becomes unstuck. That's
the theory, anyway.

A fascinating picture, but not too germane. The boat shown seems to have a
normal, single, keel and what seem to be "legs" supporting her. (I couldn't
really tell if they were legs or bilge boards, but I suspect bilge boards
would splay out rather than stand parallel with the keel.)
Assuming one doesn't have significant tides, would it be easier to refloat a
single keel or a twin keel after discovering a mud bank the hard way? I'm
thinking the single keel would come unstuck more easily by taking the
halyard out in the dinghy and heeling the boat down to reduce her draft.

I'm kind of interested in twin keels. There are more twin keel
sailboats around Britain than there are in the U.S. The purpose of
the
twin keel can be seen in this picture of St. Ives Harbor in Cornwall.

The hydrodynamic efficiency of twin keels is, as I understand it from
a non-technical point of view, a tricky problem of boat design.
It would be kind of nice to have access to some designs which the
twin
keels don't act as a brake. Uses of twin keels go beyond St Ives to
other areas which may have a dry out mooring, and of course, ease of
carrying on flat bed trailors.
