Hi

Am trying to fabricate a jetski stand on a 2006 princess p45 platform , just wondring about the size and weight cuz the princess user manual doesn't reflect any of it.

The available width on the boat is 3.2 meters

The jetski is 2011 fzr size is 3.4 meters long and1.25meters wide.


Attached is the jetski specs
Thanks

You might be pushing it a bit.
How do you intend lifting it on and off.
It might be a bit heavy for the inbuilt transom crane that was supplied with some of the Princess 45s.

Our Princess is a bit bigger and we had a Seadoo on the back for a few seasons.
And that was pushing the weight limit of our flybridge crane.
I never lifted the Seadoo onto the flybridge - just kept it on the bathing platform.

I made some chocks from Iroko (the poor mans Teak)
After getting the shape about right, I added some rubber supports that I bought from the local road trailer suppliers (cheap and easily available).

platform width may only be 3.2m, but boat beam 600-800mm above the platform level should be close to 3.8m if not more, so widthwise you should be fine (as in boat "covers" ski).
passerelle, wont be fine, WONT lift a 350kg jetski, just forget it, or reinforce transom and replace passerelle, or find a way to fit a decent crane somewhere.
Mind, platform itself (if it's like the 89 one my mate has) will be just bolted on and iffy for that weight on a moderate passage.

overall, you're pushing it (a lot!) imho

try posting a few pics so we see what passarelle you have fitted

The OP doesn't say but Princess fitted these (neat solution) cranes to the P45

John100156 (on this froum) has one fitted to his P45.
But, I know from him that it would struggle with that weight.
 
OK, didn't know that!
struggle is an understatement Mike, it's going to be close to 400kg with a bit of fuel in! that's massive

Totally true i am seriously thinking about getting a smaller jetski, maybe seadoo spark which only weights 190kg.

A friend of mine owns similar boat with the same setup mentioned that few years back he lift a 2008 seadoo rxt-x 255, am not sure how ?.

Am not willing to risk it

well at least in your boat, bathing platform seems like integral part of the hull construction, so wont have an issue resting the jetski on there. Lifting it is another matter, don't think this passerelle will cut it, check model and look at specs.

Yep, the Spark would stand more of a chance.
But, why a jetski?
They aren't very good as a tender and on a P45, a proper tender would be many times more useful.
As I say, your problem might be the same as John100156.
I'm sure he will post on here soon.

Jet boats are great fun but, are way more expensive and far less reliable than the humble RIB.
Believe me, I have had all of them in the past.
The big Jetski that you see in the photos above was not at all practicle.
I've also owned a JetRIB in the past but the best dinghy I have owned was a simple Genesis Walker Bay (I think they call it something else these days) - a conventional RIB with an outboard motor.
I over-engined it, making it a really fun little boat.
The engine almost weighted as much as the boat!!!
We outgrew it and ended up buying a huge tender for our Princess 67.
Again I opted for going big.

So, my advice is to look very closely at a more practicle solution.
The Walker Bay's hull is made from ABS plastic - I fitted a 40Hp Yamahar.
You could probably buy 3 of those for the cost of a Williams Jet boat.

Bang for buck - it was way above anything else.
This is a short video clip of our family playing with it.

having played on that tender myself I agree 100%
Brilliant set up.
Tows toys with ease.
 
Thanks akot


I wounder what would be the best size of tender that can fit my boat.

The total available width in the platform is 3.12 meters
 
I will get John100156 to join in on this thread.
He has EXACTLY this question at the moment.
I know that he has spent a lot of time researching the right tender for his boat.
I think if it hadn't been for Covid, he would have already have made his decision.
But he is "holding off" for the moment until nearer the time when he needs his tender.
His boat is a Princess 45 with the inbuilt crane.
I don't think he has a paserelle.
I'm sure he will comment though.

Thanks alot for ur feed back.

I guess Jet engines is the way to go with tenders. They are more practical.

I am still working at the moment, I have a couple of meetings this afternoon but I will contribute this evening. I have the dims for my BP and believe the crane only takes 200kg, but will read through thread and reply later...

No
Far from that
From my experience, Jets are way more UN prictacle.
To begin with, they a harder to control.
They are for less reliable.
They "suck" up stuff (ropes etc) into the jet.
OK - so you could get an outboard motor prop tangled in a rope but it would be easier to untangle than a jet.
Also, when a jet sucks something in, it can easily damage the jet system.
So, IMO, DEFINITELY - a simple outboard motor is far more practicle.
And way cheaper.

Jets can be a lot of fun - but so can an outboard motor driven tender if you specifiy it correctly.

Heavy, unreliable and expensive. They have their fans but you might not like the drawbacks.

Take a look at an Alu rib. Relatively light and tough. There is an Excel rib available with the folddown transom:
RIBs Excel VIRAGO 310 RIB. Excel Rigid Inflatable Boats.

(like the Cabrio fold down transom as recommended by Elessar).

Agreed
And I agree with the principle of an alumimum hull.
But I think it could be a sexier design than the one in your link.

Most people know on this forum that I oversize my tenders.
That Walker Bay, for example - but going to the extreme, my current 4.3m Novurania with its 70hp on a 20m Princess.
Yes, it is big but very useful - and not that much extra hassle when lifting it on/off.
I'm not suggesting that the OP should buy a 4.3 Novurania but I am suggesting that he could "push" the size to the limits.
Jonh100156 will tell you - thats what I've been encouraging him to do.
And the OP's situation is EXACTLY the same.
