Ashby trapping extremely low as always.
Any word on how much it costs?

Hi Jeremy,

The boat is actually quite curvy although looking like it has hard edges.

The following is some information on what I did with the new boat compared to the old.

In short compared to the standard boat the changes on the new boat are:

Rig and front beam back 300mm
Rear beam back 100mm
Foot shorter by 200mm
Head bigger by 200mm
Forestays back 250mm
Sidestays back 300mm
Centreboards back 150mm
Transom bigger at waterline by 25mm
Transom higher by 12mm
Deck at bow narrower by 30mm
Freeboard in bow lowered by 80mm

Boat to have new rudders and curved centreboards

It has more volume in the water than before but less out of the water and has thus far been faster up wind in nearly every condition.

Downwind has not been any slower and most of the time is slightly faster. Bearing in mind that this is all with old shape foils. We will have the new one on line in about a month. Which will be better than we currently use. This prototype boat is 3.7kg over weight too so when the production boats are coming out at about 1kg under min at 74 then 1kg lead added. They will be better again.


I hope that helps a little…

Talk is easy mate….

I have to agree with Tony. Whenever I see a picture of Glen going up wind I can't get over how low he is trapped. When I try that it feels like I'm hanging upside down and my neck muscles give out. Maybe I should take up Limbo lessons. Ed

Have you seen him get on the wire? He doesn't have a mainsheet cleat so with the main in one hand, the tiller in the other, he clips in with the hand holding the mainsheet. With his arms out holding everything (not the trap handle) he drops his butt off the side and kicks out. It's a really unnerving feeling to drop off the side of the boat without a hand on anything trapeze related.

My first Worrell, I hiked like that.The skipper beat me if I didn't. I had probs with my head being below my heart, got dizzy alot. I tried it again this past weekend and it was OK for an upwind leg but I wouldn't want to do it anymore than that. It did get your neck all twisted though.

"It has more volume in the water than before but less out of the water and has thus far been faster up wind in nearly every condition"

With every thing moved back a little, is it being set up for Australian Conditions? I can assure you he probably hasnt sailed in my lake conditions, you know, very light, shifty, light and variable....
Will the boat be faster if you sail mostly light air stuff, or will it be better in waves, chop, and the 15-20 Australian stuff?

Ed, I trapped low all weekend, only because my new trap system allowed the stopper ball to pull thru the stopper knot giving me about 5 more inches of trap line. Just enough to not be able to reach my handle to get back on the boat! Sweeeet!

For those of you who missed this past A cat weekend at Ben Halls place in FL (26 A cats)Lars Guck did a full session on trapezing before we hit the water for 15 short training sprint races (he coached from a power boat). We also took a bunch of footage of Lars on my Gel-tec flyer II in 16 - 18kns using the same mid tramp mainsheet block (no cleat)set up that Glenn uses. It will be posted on the USACA site soon.

If it looks like a duck. . . Only a matter of time until a true hard chine shows up on the scene.

I was told a true hard chine causes too much drag when bouncing sideways through the waves, as we do have some amount of leeway + hull slide no matter how good the boards are. The water flow won't stay attached when coming around that hard a corner, that's why they are rounded slightly.

Allready showed up ,look at Mark's post, and it's being built by a helluva nice guy who definitely knows a thing or 2 about fast sails and boats.If you want to see more about it go to the USACA site and look under the Predator blog.Or just click on this:

Look up Bendigo Victoria on Google Maps. Gashby grew up in a mud puddle.

The thing with his trapezing is that his feet are a long way down the side of the boat too. When you first start to trap low you tend to leave your feet on the gunwale which leads to that upside down feeling mentioned elsewhere.

The "chine" being discussed here is really not much different from what has been on the Geltek and Egner Flyer II for the last three years. It is really quite a soft curve as Glenn describes. I would call it more a tumblehome from the waterline to the deck. It's really quite obvious when you put a straight egde on the hull at the main beam. It also emphasises Glenn's comment about the bouyancy under water compared to above waterline. This was starkly illustrated to me in the last few days. I've been sailing a Boyer MKIV for some testing and it feels completely different from my Geltek. The Geltek "sits on the water" while the MKIV is more in the water. It leads to a much lighter "feel".
Glenn has always trapezed lower than most people - not feasible for those of us with older backs! Although I've never used a main cleat on an A in thirty years for either centre or rear sheeting. I think it leads to too much risk of capsize and also laziness when going to windward. I like to be able to quickly fine tune the sheeting through gusts. I also don't use the trap handle going out and use my leg straightening as I go to sheet on more. it just seems a bit quicker getting out and accelerating that way.

Mark and Todd,

Remember no-one knew the identity of "Racer X" in "Speed Racer" ... not Pops' ... not Trixie ... not Spocket ... not Chim-Chim ... well maybe Chim-Chim did.

But you guys are giving away local, Chesapeake Bay secrets!!!!

Sailmaker on not one ... or two ... but for THREE America's Cup Syndicates !!!!!

I need a new set of sails for my P19MX ... and I want them to have a RacerX sailmakers patch ... if you guys keep on "spilling the beans" I'll never get XXXX to make me a new set of sails!!!!

Way to go guys!!!!! (of course now I'm going to have to go by Cape St Claire and take a up close look-see ...)
