Wayne, I'm doing safety at the club all day Saturday. Let me know if you bring your Bitza, I'll bring a camera...

For the non-native english speakers like me, I had to search the meaning of "bitza": it's an alteration of "bits of". So I guess the name is a reference to the fact that it is made of bitza Stealth, bitza A cat and bitza home made...

Spot on with the name, it is a iteration of bits of other boats, the T foils I do think work ( but not quite in the way we think ) the A class hulls work very effectively and this particular design had been set up for heavy weight fat boys like me and as a plus had more volume foward of the beam than any other design I had seen, and there are loads of other " bitsa other boats ". In fact this is Bitsa3 as my other two boats were build ups from what ever I could lay my hands on ( see I'm really a recycler and very PC ).

At the moment I have an A class wing mast and sail which I want to try, just to see what these really high aspect sails are really like. Looking at the SCHRS calculator, with the reduced length, reduced width ( 2400mm as I feel my Stealth is over width ie the righting moment overcomes the bouyancy of the hull creating unwanted drag )and smaller sail area, the handicap is acutally slightly lower than an optimised F16.

Foils are Stealth, there is no point in reinventing a good wheel.

good luck with the new boat.
Are the rudders not to far from the stern? Its he the first time I see this.

Well, you should look at Moth or skiffs to see how far they do hang their rudders, Wayne's is fairly sedate compared to those

Note that the reasons for those long gantry are different: The Moth want the rudder way way back because it will reduce the size of the T-foil as there will be less weight to lift due to the increased lever effect. Or something.

On the skiffs it is as far back as possible so it stays in the water when they fly their ridiculous spinnakers which are pulling the whole boat out of the water (kidding, it's because there is a better undisturbed flow further back, the smaller the boat, the longer the gantry. 12' skiffs are insane.).

As for Bitza there is not enough space between the rear beam and the transom to fit the tiller bars.

It's all perfectly legal, the rules only limit the hull length, and as long as they are not buoyant you can make the rudder gantry as long as you want...

The new Loday/White F18 Shockwave has similar length gantry as the Bitza. You might be able to make them out in the attached photo, but I think they will definitely work for this F16 as the distance from the transom to the rear beam is tiny compared to a Blade.

It is all good. I bet there are others than Wayne waiting for this creation to get on the water (I know I am).

Excellent photo find Pepin.
Here's a couple more photo's of the Bitza, bow and 6 degree centre board angle and the hull section at the stern

The bottom gantry doesnt look as strong as the top one, not that I know anything about building though.
