G'day,
Sorry about that. I see a rule, I see a
challenge to get round it. Could never be bothered doing so, but like the
mental exercise.
Current state is a cedar or kiri core, epoxy and
glass skins. Box section carbon/glass beams, ballestron rig with box boom
and rudders hung off the inboard side of the lee hull.
Options that we have tried and that we know
work: In hull rudders, schooner rig, alloy beams, foam hulls and open
top boom
Options we are currently experimenting with:
drum rudders, wing masts, other methods of reefing, building the boat from flat
panels built on a bench but only glassed on one side.
regards,
Rob

Now you're sounding like an America's cup designer. I think
once you get get
involved in rules and ratings the boats suffer. Let's
forget that silly
exercise and go back to trying to make the best sailboat
we can.
Here's a question, I know harry is a work in progress but if I were
to send
the money today what is the current state of harry? Which core
material, which
rig etc.???

Or maybe we could get creative with the dimensions of the bow
sprit so that it
was an extension of the bows but just clear of the water
at rest. 8.5m
waterline at rest, 11.2m overall.

For what it's worth most of the boats to the rule in
NZ are cats, weighing
in
around 1200 kg and 48-52 m2 in sail, a
lot staying short of the max beam. I
can see why the length
restriction would be an issue, wonder if they'd
accept
the length
of the ww hull only!

OOps, just found the next post. Wow!
Definitely a catamaran rule, but
some
scope for a proa.
Near enough a Visionarry area rig on a slightly longer
Elementarry! When do we start?
regards,
Rob

Thanks David for this information.
Looks very conservative ;-)
If
you do not take in account the differencd in wind
conditions
betweeen NZ and Switzerland, and the
difference between lake and open
sea, naturally.
To compare:
M2 class:
max length 8.5m
beam
unlimited
Overall length 11.2m
trapezes and wings allowed
height above wl
16.6m
no engine
no headroom needed
in hulls
must be unsinkable
