Twin jet operation

[jointventureII]

Hi forum,

Tomorrow I'll be having a go on a twin jet operated boat. I've used single jets a lot, which are fantastically manoeuvrable, but I've never tried twins before.

Any tips from experienced users? Barring the "bow goes the way of the wheel whether ahead or astern" rule , are there any other tips or tricks? The jets can be individually steered so this must mean incredible manoeuvrability?

Take video…..take photos…..post on forum ??

Discretion is paramount ^^^ in theses circles.

take covert video…..take covert photos….post on forum under a different user name. Maybe #therealporto ?

If I end up stacking it into the wall, I'm fairly sure there will be plenty of people to take photos & videos for me!

Please do take a video showing your best hand brake turn - and one showing what happens when you drop both buckets at top speed.

I was moored next to a 125 ft Azimut on jet drives for a few days ( kids played together)

The only pearl of wisdom I got from the owner was that the fuel bill was stratospheric

I skipper a boat with twin Hamilton jets every now and then and it is very manoeuvrable in close quarters, where the key thing is to set your revs and just use the buckets and wheel to move pretty much in whichever direction you want to.

This is what happens when you do emergency stop on twin jets

Unless this is via a joystick(or sticks) and some blackbox wizardry I can't see how it would work; it could offer the ability to move in more or less any direction while controlling heading though.

I've phoned a couple of mates who have experience with twin jets, they said the same - set the revs but keep it low / gentle at the beginning when getting used to it, that includes small lateral movement of the buckets.

Also, one tip (TBC if it's actually any good) was to angle them both 20° inwards and then you can use the same principles as a standard shaft drive

Unless you’re in combinator mode, buckets for slow speed speed control, revs for high speed speed control. Don’t be tempted to turn on the buckets at speed until you get used to it, you’ll launch your crew overboard quite quickly.
