I am looking to buy a Avon Seasport 320 Jet Rib for my Princess V40 but is it not to wide and long for a V40 and is the weight not to high? It is mainly because wife and children want to ski and play behind it, any recomendations very welcome...

Why bother with the weight, expense and size of a jet RIB. I have a 3.1 RIB with a 10hp engine that will do 16-17 kt's with me in it, if I had a 15hp I think Skiing would become a possibility and all for half the price and weight.

If fitted with passerelle, think weight limit is 150kg, and believe avon jet is about 250kg. Might be worth asking Princess as they should be know if it's possible.

CAD drawing available

compie, the 320 with steering wheel weighs 240kg, the motorbike seat/handlebar version weighs 210. We just bort the sterring wheel version

I think your prob will be the bathing platform on V40 is nowhere near deep enough - the keel of the jetrib would be cantilevered out over back of boat. You also need a crane or passerelle to lift it

I have a CAD drawing of the steering wheel version, fully dimensioned and scaleable, given to me by Avon. It has cross sections of the hull dimensioned to enable you to make chocks without having the boat to measure - that's why I got it. I can email if you want it - it can be opened and read in MSWord as an image. However the crucial dimension for you is that it is 1710mm beam.

Re: watersking- not great on a jetrib

I wouldn't choose a jet rib if you want to waterski - the blimmin things seem so overpowered (or summink) that it is not erm grunty enough to lift you out - and/or when it does lift you out it can rip your arms off and whiz off up to 40 knots. Whereas on a nice shaftdrive propellory boat of any size, much easier.

Hi,

I'm new to this group, but know a bit about this. I used to have a 15' jetboat, and towing is not much fun! You are much better off with a prop-powered boat. From what I can see, it is not more maintenance, etc, if anything it seems easier. If you get a prop guard, you dont have to worry about people getting to close to prop, and I think generally it's cheaper.
I dont understand the physics of it all, but apparently because on a jet boat there is very little "in" the water, you get the "tail-wagging-the-dog" effect when the skier goes wide, the boat's back end tends to follow it! Plus a jet does not have the initial smoothness of power compared to a prop. You either don't have enough or pull the poor skier apart.
My 2 cents says outboard all the way.

I went through this thought process a few months ago. I concluded that 3-3.2m is too big, and anything over 110kg is too heavy. I've just ordered a 2.8m avon rib package with 10hp enginge and jockey console. All up is 108kg and should fit on the back. Had to have some new chocks made for the bathing platform though.

Here is a pic with the old 2.5m dinghy on the back (that i still have but don't want - hint)...

I have a 110kg limit on my passerelle. They have a little margin for error on, and you can up-rate them by adjusting a pressure screw on the hydraulic unit (this has a lead seal on it, that if broken, breaks warranty) - so I've tried to keep on the 110kg limit. I intend to pull the kids in an inflatable tyre, not waterski, so should be OK with the 10hp. I think you'll need 15hp for skiing? Could try a valiant D300?
