MUSICBOX2, CABIN SAILBOAT, 15' X 6-1/2',
800 POUNDS EMPTY
the same as Musicbox3
but with a bow transom.
Musicbox2 looks a lot like
a shallow draft Micro and that's what she's supposed to
be. I helped build a Micro a few years back and have spent
several hours sailing one in both light and heavy winds.
Micro certainly sails well, especially considering she
will easily host six adults.
I thought Micro had two
shortcomings. Her keel can be a challenge to build and
makes launching and beaching difficult. And her tall rig
can be an effort to put up. Perhaps both features contribute
to her good sailing, but she's not something you'd want
to trailer to a lake for a short Impulse sail.
Musicbox2 is about
the same hull size and I believe her to be even roomier.
Ballast is a thick bottom and steel bars bolted to the
bulkheads Inside - simple and cheap. Lately I've been
able to do more extensive capsize studies having found
the free "Hullform"
program on the Internet. It shows Muslcbox2 to be 'self
righting" up to about 70 degrees. Not sure what that
means although to most of us that would be a fearsome
angle, in the old days Chapelle. sad that if a sharpie
could right from a 45 degree heel, It was "self righting'.
But I see today's blue water keel boat sailors worry If
they can't self right quickly from rolling 150 degrees,
i.e. almost Inverted!
Also I've used my favorite
pivoting leeboard and rudder with a gaff rig, stepped
off center on a tabernacle for easy boarding and rigging.
There's a boarding ladder built Into the bow. A mizzen
could be added straight away, but for impulse sailing
this single sail rig Is better. Musicbox2 takes five sheets
of 1/2" plywood, six sheets of 3/8" plywood,
and five sheets of 1/4* plywood, with simple glue and
