G'day,
The 64 dollar question! First, we will try
sailing harry and Visionarry with only the main and see how it works.
Should not be a problem, but needs to be checked. If there is a balance
problem, then a wing mast would be a partial (maybe complete) solution as it
moves the centre of effort forward, probably quite a distance vs a rig with a
large round mast. Next thing to try is raking the mast forward (easy with
a wing, less easy with a round tube) which will move the coe forward and if the
mast is sitting on a stub mast (which is vertical), it will also reduce the
sheeting loads. At the expense of a peculiar looking rig, maybe with
upwind deficiencies, maybe with interesting structural problems.
The wing mast on Elementarry will sit on a stub
mast, and have variable rake so we shall see.
regards,
rob

How would you translate this to a full size Harry? Would
you take it up to
similar sail area to the original? i.e. one big mast
instead of two small
ones.

Re: [harryproa] Una Rig
G'day,
Cut a hole in the side of the
hull, put in a mast tube and used one of the
existing rigs. Next step
is to build a wing mast, as soon as the materials
arrive.
Sail area
is 11 sqm. Sailed on the weekend in 5-12 knots. Went past a
Nacra
18sq and a Hobie 17 downwind (both seemed to be trying pretty hard)
and was
pointing as high and as fast upwind, although I was a fair way
behind them so
the speed may not be correct. They were trapezing, I
was sitting in the
middle of the tramp, so could definitely use some more
power.
Regards,
Rob

Did you simply put one of the existing (
schooner )rigs in the middle
or did you increase the size to
try and match sail
areas??
