for that boat would be a sprite boom that has a tendency to pull the
mast back straight and is more weatherly than the regular boom. Most
boats with a boom like that are sailed with boom hauled in tight when
sailing to windward thus putting a lot of strain on an unstayed mast.
With a spritboom the sail can be left far off the wind and get the same
or more speed to windward with less push to leeward. If she were my boat
I would either stay the mast or change the rig. Maybe change her to
ketch and gets some load off the mainmast. Of course you give up a
little windward ability and gain a lot of control.

Bruce,
Is that the sail shown on the Micro Navigator plans for the
tabernacle version mast? It isn't clear from the one view how it is
rigged. I'll eyeball your currently posted drawings to get a feel
for how it should work.
I have the bulkheads built for my Micro Navigator build and just
finished butting one of the sides. I am using a strongback so when I
finish the second side I can begin to mount the bulkheads on the
stongback and I'll be 3D...
Sincerely,
Gene T.

I agree with your analysis. Also, I've seen this 'reaching spinnaker'
drawn on several of Bolger's sailboats, one that comes to mind is the
upgraded AS-29, and I am tempted to try one on my Micro Navigator.
P&S, on the clew?

P&S, on the clew?

Using the pole when going to weather would make the loading on the halyard so great (assuming you're sailing in waves) that I'd expect to break something.
However, rigging the same scrap of sailcloth as a jib to weather and a spinnaker off the wind would get max advantage out of a minimum of gear. A jib with a whisker pole to the clew would not be nearly as effective off the wind. At least that's the way I would call it.

I think this sailboat has a type of Cat Rig. This boat doesn't have
a jib. Nor does it have any stays, standing or running. The foresail
is a reaching spinnaker, and its spar is a spinnaker pole.
