Can you give us a link or something with more info please?
They look very interesting! How much are they etc would be good.
cheers

Not available yet, as they're not launching until early next year.They look very interesting! How much are they etc would be good.

We're finalising full details and specs at the moment, with a couple of demo models available for sale at a discount now, the 'finished' factory version will be out early next year.
Drop me a pm if you want details!
I would get one of the n/a Sea-Doo 4tec jetboats for ease of use and maintenance, they do a 310hp twin engine if you want to go quick-ish reliably, if looked after they will do hundereds of hours.
With regard to the new jetboat being released, its design is very similar to this...

What motor/pump are you using?

Forget them...buy a outboard...rubbish in reverse..only steer when on the power...no natural rudder...heavy on juice...unreliable..with a Jet you loose in the region of 25%-30% of the hp over a standard prop. Call it if you like transmission losses bit like having 4 wheel drive when 2 will do on tarmac in the dry( RWD only of course !!! )
Oh and they tend to have shallow V hulls which means they slam badly in a sea way. When used in rough seas they also get cavitation draw air rather than water down the impeller so basically like dipping the clutch given the water intake is well forward and of shallow draft compared to a outboard / sterndrive / shaft.
They also don't take kindly to small stones going up the impeller tube...

This is a great laugh... http://www.boatshed.com/stealth_craft-boat-55217.h...
Sold now but a saw one for sale this week with a 70 2 stroke Yamaha on which is my personal top engine. Bullet proof and very quick. I have used the one above quite a bit..
Can't remember where I saw the one with the 70 for sale this week...on the net anyway and was priced at £3250 as well.

What about one of these instead?
Can be used in salt water no problem, easy to maintain Suzuki engine.
pm me if you want a sea trial.
That looks and sounds like an interesting little beast Nic Can be used in salt water no problem, easy to maintain Suzuki engine.

Any more specs or are you bound to secrecy for a bit longer ?
This particular model is due for launch early next year, we're putting final touches and specifications together now.
Suzuki 1400cc engine with a custom made jet pump unit. Custom made because we can then replace them a lot more inexpensively if/when required.
It's actually a very simple little boat. A bit like a Caterham/Westfield for the water. Point and squirt, 270 degree steering with pedal throttle means you can literally spin it in a circle in its own length, fast, from almost full speed, without taking your hands off the wheel. Nuts, but great fun.
I agree with Rumrunner, they don't reverse steer as well as an outboard. But how often do you need to reverse an 11 foot boat that turns in its own length with a blip on the throttle? Yes, they have no natural rudder, but they also have no gears either, you always have steering because the jet pump is always moving (albeit very slowly at idle), so that negates the issue. Sterndrive is pretty much the same anyway, so if you're used to that....
Water intake on these isn't too far forward, so cavitation isn't such an issue, or at least hasn't been on sea trials so far. Anyway, it's not the sort of boat you use in heavy seas, leave that for the blue water cruisers. It's a fast marina boat, or a sunny day jet-ski for those who want to stay (relatively) dry. I've been using one as a tender.
You can also compare stones going through the pump with running aground with a prop driven boat. You can run a jet boat in 10cm of water (a deep puddle) without breaking anything. You can even beach it backwards and it won't do any harm. No prop to break or worry about, it's completely flat along the bottom.
As for fuel ecomony, it's really not what you buy one of these for!
What they do very, very well indeed, far, far better than any prop driven boat, is getting up to speed and handling.
They 'drift' beautifully, in a way that prop boats simply cannot because of their nature. Put better than words ever can, they can do this;

He puts his foot down at 47 seconds, running full tilt at 48 seconds. That's fast.
The new model in early production now is a 4 seater version, it's likely to be a similar market to the 'Stealth' (or 'Zippa') boats, but with jet drive instead of outboard. Similar prices too.
We'll be doing some more testing in Cardiff Bay in a couple of weeks, drop me a pm if you fancy a go.
We have a lot of ski's that a beached or left at the edge of the shoreline..with the outboard we just trim up..but the ski's get sand and stones in then people open the tap's.
One thing is though they are more people friendly not having a slashing / mincing device handing off the back..

With a proper, decent strainer on the inlet (which Sea-doo don't want you to have given the prices of their replacement jet pumps), you won't be able to suck up enough crud to damage the jet. The worst you'll get is weeds that block the inlet strainer, which just need pulling back through to clear it.One thing is though they are more people friendly not having a slashing / mincing device handing off the back..
A properly designed jet pump is actually very reliable. Problem is, there's relatively little competition in the market, so no reason to make them more reliable or better designed (or cheaper).
Hence us starting from scratch with the pump!
If you're beaching your skis and then getting stones etc up the pump you're not doin it right.
Drag it off the beach into knee high water and lift the rear up and down for 5 deconds or so and this clears the pump unit out.
Been doing this for 10 years on stand-ups, 2, 3 and 4 seater skis without an issue.
If you try and start the ski in ankle high water you're going to have problems.

I don't use ski's that much just watch the others when I am instructing power and sail off the beach..and charter guests on other charter boats with ski's. Always had a decent 14/ 15ft RIB with 50-70hp outboard as a tender.Drag it off the beach into knee high water and lift the rear up and down for 5 deconds or so and this clears the pump unit out.

Seen many accidents over the years and especially in the Carib where ski's have been banned in a lot places due to people coming off the gas in a panic situation, turning the bars and going straight on.

I had a speedster 200 for a year - 430 BHP - twin engine.
On paper a good idea, but the hull design rendered it next to useless for use on coastal waters as if there was any sort of chop at all it was dreadful
Ended up chopping it in for a 150 BHP boston whaler, which is used lots more and in the real world Is probably "quicker" as unless the sea is very bad performance seems unaffected and it gives a lot more confidence.
If I was somewhere with mill/pond calm water it would be different I think.
