Hi,
Had first sail, after getting mast up.
Nearly capsized.
Rig too big!.
MOstly succesful trial though, especaially good response from the steering - steered much quicker than before (i have added some 300mm of length in the rudder).
I had the first reef main and full jib (this is the harrigami 11m mast and 9m mainluff rig).
The balance has come forward as hoped so that less luffing up as before wth the schooner and sail area aft.
The lifting pole did work easily - after getting 50mm diameter pipe, then it was quite trouble free. Only seem to have the gear at the boom side obstructing the mast from getting in close against the pole.
Not sure how big you'd attempt with this style of mast raising, ut seems fine for elementarry size.
Doug
Still hot

No mould, all the panels were built on a flat table. Guys are now building another one, 15m long so fewer joins next time. The shape of the bent bits is more or less a semi circle, although this can be controlled by the amount and location of the glass. Sorry I missed you, too much going on. rob

hi rob,
what was the mould?
and am at maylands from now - tuesday 12:30 on - down on the water trying the lifting pole or in the shed.

Nothing special. The core is left out of the areas to be bent. Could get tighter curves by cutting a V in a cored panel and more rigid curves by laying up only one side of the core and then glassing the other side when bent, but for what I wanted, no core on the bends works very well.
rob (currently in Perth, will try and get out to Maylands tomorrow or Wednesday, but have a very full schedule so may not make it)
did you do something special when bending?
could you run through the steps.

Table finish is perfect. Could have used gel coat, but did not want the weight. Thought we had an additive for the resin which would have been a uv filter, but it did not work. Hull is fair, except for the foam ends and the join in the lee hull, which is fair for the water flow, but not perfectly symmetric due to the location of the glass overlaps.
The top of the ends are blown polystyrene blocks, the bottom extruded polystyrene sheets hot melt glued together. The top is far easier to work with, and cheaper. Got them on, shaped and glassed last Monday.
2 more weeks of school hols and I can get back into it.

Hi Rob,
Was solitarry faired with bog - or was the flat table finish fair enough?

Should get mast in this weekend, and sail on the upper river a bit too......
42 degrees Celsius coming on Sunday. --- On Wed, 13/1/10, Mike Crawford <jmichael@gwi. net> wrote:

You're right. I'm not sure anything is going to compare to Fercot's rig in the following areas: - Ability to maintain ideal sail shape in any wind strength. - Ability to keep each part of the sail and wishbone frame lightly loaded. - Simplicity of mast -- no rotation required. Loading and mast simplicity are good, but not my primary focus. To me those are benefits, but higher loading and mast rotation can be designed for. Though you could definitely argue that lighter loading and more simplicity translates into less structure, which translates into more speed...... My greater concern is maintaining a great foil shape without manual intervention on each shunt. --- I currently sail a Stiletto 27 catamaran with a rotating wing mast carrying Ullman pentex mylar sails that have semi-stiff
battens. I get a pretty good leading edge on each tack simply from pressure on the sail track rotating the mast. But it could definitely be better, so people who race the boats install a mast rotator that introduces yet two more lines that need to be adjusted every time the boat and wind change direction. The sail is cut well and has a beautiful arc to it, allowing me to sail in winds so light that others stand still. The high SA/D also helps, but it wouldn't do a whole lot without the right shape. The problem is that battens which are stiff enough to handle big winds are too stiff to flip over from one side to the other in light winds. That means I have to switch the battens over myself, and unfortunately tugging at sheets or the traveler won't do it in really light winds. The one thing that works is if I launch myself into the air, aiming for the other side of the 8' wide copckpit, grab onto
the boom in the middle of my arc, and swing on it once like a monkey as my legs continue to the other side. That sets the battens. That's a lot of work if I just want to have a relaxing sail. I got the 27' model instead of the 30' model because the jib doesn't require a winch -- you can either manhandle it with a standard fiddle block, or put a block on the clew for a 2:1 purchase. Either way would let me avoid being a winch monkey on lazy days. But now I am apparently a batten monkey. So I look at Fercot's rig with much appreciation. No batten flipping, no change of sail arc no matter what the wind strength, no messing with sheets, no hydraulic or electric camber inducers. It's just taking me time to get over my resistance to the junk design in general, and all those strings in specific. But that discomfort is something I should probably get over.
This rig probably does the best job at my primary goal of maintaining ideal wing shape, and addresses the secondary goals of loading and mast simplicity. I'm not sure any of the other options do that. --- I would consider a variation of the Omer if it didn't require a hinged boom, as well a variation of the snake battens, or light battens, if the sail will set itself in light wind. Perhaps, maybe, with the help of a single continuous line to force camber in the lightest winds. But the higher loading on the luff and leach, though not a primary concern, could make it tough for the camber to automatically switch from one side to another. Which brings me back to Fercot's rig. On comforting bit of information was that his boat is faster, and tacks better, than a standard Tiki 30, even with the burden and windage of the deck pod. That's pretty impressive because the 30 already has a
lightship SA/D around 36. Thus, he has proven that the theory works. - Mike Arto Hakkarainen wrote:

The problem with this rig and omerwingsail and other such soft wings could be tensioning the luff and keeping its shape in stronger winds. I assume that in order to keep the shape the luff needs to be quite tight which means higher loads and need for less stretchy sailcloth which both could be against your goal of light loads on the rig.
