Jet Drives

Is there a 'useful' handbook/manual available on the 'best' way to drive these?

there aint really any books that can teach you to drive jets , just need to practice plenty or go out in a boat with someone that knows what there doing,

"or go out in a boat with someone that knows what there doing,"

Doesn't this just mean or go out in with someone who 'thinks' they know what their doing?

How can you tell the difference?

They might be making a complete 'dogs breakfast' of it & just getting away with it.
Somewhere, there must (even if its based on a manufacturers handbook) be something which is more informative.

I haven't seen a good published book on driving jets (and it's really only the "peculiarities" of the drive unit that make it any different - apart from that it's still a boat and subject to all the conventional boat-driving stuff), but some of the places where they teach people to drive in jet boats have produced their own material and may be prepared to share if you ask them nicely.

In Scotland, I would approach organisations like Falcke Nutec, or RGIT, or MRI at Stonehaven and talk nicely to them. I don't have the local knowledge for the south coast, but I'd maybe start with Warsash and if they can't help they may at least point you in the right direction.

If you don't get anywhere, feel free to pm me and I can send you my own thoughts on driving jets. There are really only 2 key things you need to get your head around, and if you understand those the rest comes with practice

Surely it's get in one and get on with it 'til you get the hang of it? I've driven a jet, I found close quarter handling a bit of a nightmare at first. Remembering the bucket is the tricky bit.

.

surely after all your years at sae you'd know when someone was winging it?

Look at discharge books and relevant documentation to see if a pro has the relevant experience. 2 best local drivers I know to you are Johhny tug boat. Got an OD by the timver wharf in Pole or Jasper Andersen in Southampton.

Once you get your head round a jet's capability and you get a few hundred hours in the control they offer you is stunning.

Call me if you want and I'll talk you trough a few things

call me foolish but....

I just got in on friday and got on with it. i've never driven a boat before anywhere, i have all the safety kit and extensively researched launching etc.

1 spent 2 hours at various speeds and to be honest, theres not a lot to it. high speed is easier than low as you have far more drive to utilise. low speed was a bit hairy at first, i zig zagged my way out of the harbour but after some practice with coming along side the jetty etc i got the hang of it.
basically - no drive - no steer!

you need to blip the throttle to get the best out of manouverability at slow speed.

more experienced people may disagree with my comments above but this is just my opinion so please go easy on me!

another 8 hours plus training and i'll be taking my family out too!

Where are you on the south coast? If you're anywhere near Salcombe you can come out in our demonstrator and play if you like?

Another graduate from The School of Life! And it saved paying a Consultant/Instructor who probably just trained themselves anyway .

a few things omitted....

well, didn't want to look like a fool but that sounds like me 2 mins after leaving the harbour..... 32 mph with 1.5 ft waves.... soon slowed down.

the biggest issue i had with the rib was how the hell to slow down when i'm holding nto the wheel so tight!!!!!

maybe a floor throttle?

Hold on to the base of the remote box and use your thumb and finger to control the throttle. Top tip passed on to me when I first started using a boat with an outboard that could do more than 8 knotts.

I've never driven a jet drive. What are the different characteristics compared to outboards and stern drives?

And how do you trim the motor?

Well, if you buy the right jet drive you get one with a bucket that not only moves from side to side but also up and down to trim the boat. Curiously enough I might just have one under my desk, now where is that JSP chap it would be just right for an Avon 5.4m.

Of course anyone who wants to know how one works could do worse than read the famous Ribnet Jetboats thread, which ran to 195 posts and entertained us one dark winter

... Recently I overheard someone discussing the throttle settings on our local 85 - apparently there are two:

1. Go
2. No Go

It is if you were at Seawork this year - they had it linked up to a couple of big 292's (iirc) and you stood at a helm position with real controls - was an effective marketing tool
