That Cat has another feature I'd considered, a stepped hull. We've been selling stepped hulled Boards up until recently and they work really well. They give the water line length up wind then lift onto the step and plane at up to 30 knots offwind, and that's a board weighing close to 18 kilos (Which is very heavy in windsurfboardworld). 

Phase 2 of this, if there was too much drag would immediately be to step the hull, think I'd put it further aft than they've done with that 'Mediatis' Cat.

I should also say at this point how very much I really appreciate all this help and input, it does get a bit scary when reality bites, but that video of the twin windsurfers actually gave me a bit more heart, they were heavy old things, the rig was atrocious and yet it was yotting about at a fair old lick.

Just to reiterate the negatives of Cats, the lee hull dipping and the close quarter slow to tack, so I'm trying to get the best of both worlds, it ill be a compromise, no question , it's just wether the outcome delivers more plus's than minus's and will it be a fun ride. That and wondering how Queen Mary will react when I enter it with the same PY as a Streaker for the Bloody Mary next year.

Anyone care to take a stab at what PY it will end up with?

Well my target is to beat the jolly old Sea Standard boat at our club which is 973 the 470. 

Which, if it can get uphill on a par with a Contender, which it should, then with the kite downhill?

I don't think its an unreasonable target to start with. The Other Boat that lurks around that figure is my old stomping ground the RS 500. So I shall race them in a few races in varying conditions and see what happens.

Then again, it could be my wonder planing rockers kick in and we see 950 or an eye watering Alto beating 925..

It'll be interesting finding out. But even if I fail, and I end up  around 1000 but don't fall in all the time that in itself would be a minor victory.


And if my mate in his Phantom is even on the same leg of the course I'm on at any given moment other than just after the start, I shall eat the entire boat. Wink

GRF, you are deluded.  In it's current form this boat cannot get upwind in the sea as quick as a Contender.  In its current form this boat cannot work, everyone knows it, but don't want to come out and say it.  Save some money and learn how to sail the RS100.  Mark my words.

Atrocity.

Atrocity.

Actually everyone doesn't know it because it hasn't been made and tested yet.  It could well be that the design is going to change several times and becomes a much more refined product with some ideas thrown out and new ideas put in.  If G.R.F. is willing to actually put money in to see this through, I think we're all happy to see what comes of it.  If nothing else, it could potentially produce some interesting data.

Of course it's going nowhere 'in its current form' !! It's 'current form' is simply a design that's being tested!  At least grumpf has the guts to put his moneywhere his mouth is and try something new.  Even if it doesn't work it will be an interesting project and I think we're all getting something from seeing his thoughts - which he's not too proud to share.

Well, perhaps not all of us.....just those with an open mind.
the same, but different...

Is it indeed? Well that has to be the target to achieve then.

Well it's now crunch time, had all the figures back last thing Friday which I have to say made my eyes water.

Don't costs escalate when your having fun?

I've now got to make a tough decision, basically I either get one at a not unreasonable cost but it won't be a terribly long term affair, just a poly wrapped tryout which if it lasted a season would be a miracle, this tests all the theorys then ordinarily would then go off to the mould makers to build a 'proper' boat.

Or, I go for building a 'proper' boat straight off and it starts getting price of a small car territory but then if it does what the boys assure me it will do, then they're immediately in a position to build more, but it's gone about four grand over what I'd initially budgeted and that's less the VaT.

Either way and perhaps what I wasn't totally clear from in the first place to get a lasting product I'll end up having to pay the second option anyway, but going route one first puts 50% on cost.

A dilemma that I'm pondering on over the weekend.

I may have to introduce them to a pencil sharpener.
