Re: [bolger] Re: performance sharpie design
I did a quickie model of Todd's boat in Hulls. Since Hulls won't do a
shallow arch bottom, I did it as a shallow vee instead. Based on the
righting moment calculations, I have to agree that it has more than enough
form stability to dispense with a ballast keel all together. While it is a
handsome hull in profile, looking at it in 3D wireframe it is really, really
fat looking. Cutting the beam to 6' looks a lot better and would probably
perform better.
I think it would not be all that easy to get the all up weight down to 250
lbs without getting a little bit exotic with the construction. The bottom
is
going to need a lot of floors to reinforce it and help it hold its shape.
Getting the lightweight hull to handle the loads generated by the high
powered rig is going to be tricky. It's going to be tough to build much in
the way of cruising
accommodations without increasing the weight so much the performance
suffers.

Shoal draft is what I'm after as well. Easy to trailer easy to
launch, retractable keel details. Tring to get an effiecient hull to
get the most bang for my buck from a simple rig.
What I want to do ? Sail twice as fast as the wind, with a shoal
draft 16 foot mono hull, with a cat yawl shapie rig. Cabin space for
two sleep cramped.

I am just going by eye. What are the dimension. It
isn't the curvature I was refering to buth the fact
the if heeled (though perhaps that isn't in the plans,
the assymytry between the sides and bottom may affect
the hydro undesireably
There isn't anything inherently wrong with bulds, and
there isn't anything about what kind this is. I just
saw two things, one is no shoal draft, which is a lot
of the sharpie apeal, and the other depending on what
kind of gyzmo this is, is the difficulty of getting it
right. Again there isn't anything wrong with a simple
rig, but you will get the most bang and performance
for the buck, your experience, time spent sorting out
details, if no particular part of you boat is
dispropotionately more complex than the other. If the
fin keel is desined to give you lift to windward that
your sail plan can't match, what is the point. But I
sdon't know thatthat is the case, since your design
isn't in any detail yet.
The hull shape reminds me of a trimaran, that's one
way to get that kind of form stability.
If you want advice try to be as specific as possible,
ideas like "I want the hull to just <BR>

Thanks for the ideas . Not to round from mid ship back to the stern.
Keel Bulb, use somthing like the his her schooner dagger board.
Whats wrong with putting the simple rig on the so called complex hull.
I'm not much of a designer I know, but would love to hear how to make
this shape or similar shape work . Seems to me similar shapes have
proven to be very stable and very fast.
Its not so much wider than the micro.
Why do I need more rocker? How much rocker? I want the hull to just
kiss the water while still. "like in the not to scale drawing". If
this is achievable?
Thanks ,
Todd

Subject: [bolger] performance sharpie design
I have posted a design that I drew with my paint program in pictures.
kind of a scaled down performance sharpie 6.5. Its sort of a sharpie
isn't it?
I want to build as soon as i figure out the numbers.
What do you think?

It doesn't look all that much like a sharpie, It is hugely fat, if it
ever did get over on it's side, there would be a tremendous assymetry
to the hull due to the very rounded sides and flat bottom. A bulb
keel would destroy her ability to be shoal draft (retractible?), and
one would have to wonder why embrace all that complexity below the
water line, and then put such a plan rig above.
People have tried this kind of approach before, but with narrower
hulls. Something part way might be found under the Norwalk Island
Sharpie. If you want more info on sharpies, look at Ruel Parker's
book.
To make your design efforts easier you might look for one of the hull
design programs out there. I have low end pro version, so I don't
know much about the freebies, except they exist.
