MIXER, ROW/SAIL SKIFF, 12' X 4', 90
Mixer is a stab at mixing some features
of my prams with the features of the original Roar rowboat.
The prototype Mixer was built to perfection by David Boston
of Factoryville, Pa. That's him sailing on vacation in
Mixer's beam is half way between that
which has "stand up and walk around" stability,
and that of Roar, which is too tippy for serious sailing.
They all have a similar multichine cross section. Dave
was very happy with the stability of the prototype. He
reports sailing in white caps with no troubles.
pointy bow causes a loss in carrying capacity compared
to a pram bow. Mixer would need to be stretched at least
a foot longer to meet Piccup's capacity. But I left Mixer
at 12 feet for two reasons. I've found a 12 footer can
be cartopped without bow tie downs and few new cars have
bumpers suitable for bow ties. Longer hulls usually need
bow ties (except for narrow jobs like Toto). Also, the
12 footer can still be got out of four sheets of 1/4"
plywood and may be a tad lighter than Piccup. At any rate,
Dave's Mixer has sailed with two adults aboard and was
Mixer's got the exact same interior
layout (a 6.5' open cockpit between two large flotation/storage
chambers) as Piccup for all the same reasons. So here
is a cartopper with capacity for two adults or for camping
one adult with a flat floor large enough to sleep on and
lots of dry storage.
sail rig is identical to Piccup's. If you look at my leeboards
you'll see they pivot at a lower hull guard while their
tops are braced to take loads both ways and only one board
is required. Essentially they are centerboards mounted
outside the hull. But no centerboard case is required
and there is no need to handle the board in tacking as
with loose leeboards. For anyone thinking about converting
a centerboard design to leeboards, note that a leeboard
should be mounted at the hull's broadest beam to be in
flow parallel to the hull's motion. The sail rig then
needs to be placed for proper balance.
