Lifting system for jetski, hobie.

Anyone have ideas to lift a jetski to the front of the boat or/and a hobie.

Talking about multihulls like lagoon 420, fp or nautitech in same size.

And keep the small rib in the back.

I'm having a hard time visualizing what you're talking about. Are you actually planning to store a jet ski and/or a Hobie cat on the foredeck of a cruising catamaran???

1.) Get an extra long spinnaker pole, use the spinnaker halyard for lifting, and a couple of guys for sideways control.
option 2.) Mount some padeyes on the decks, use 2 spinnaker poles to create a kind of "A-frame" to clear the seagull catcher. Use the spinnaker halyard for lift.

Option 3.) Buy a trawler instead of a sailing catamaran, these can have a nice hyraulic crane to handle all these things. A sailing cat is not really designed to be loaded up in this manner, unless you are only running in protected waters.

I would hate to have a jetski jumping around on my foredeck in bad weather, it could easily smash something critical like the forebeam....

Me too, those jetskis weigh tons, I think you will probably need a much bigger boat!!

Open one of the sugarscoops hydraulically, with a telescoping ride-up dock, after stretching the cat a bit. Your special sea and anchor detail can easily disassemble a couple Hobies and store them in the crew's lounge. This may cut into the number of Tees on your driving range.

Small Crane

The only practical/affordable way to get something that big and heavy up on the foredeck is to install a small crane. There are a few quality manufacturers that produce some relatively inexpensive cranes. I say relatively because the other option is to go with a hydralic crane and then we're talking tens of thousands of dollars. Even then, you'll want to keep the jetski down to a small size because the big three seaters can easily weigh over 2000 lbs. which is beyond the scope of conventional cranes.

The highest weight that one of our systems, the 10000T, can handle is around 1000 lbs. The picture below is a model 6500T which has the same basic design of the 10000T but is only rated 650 lbs. These cranes are our low-profile models as they lower down when not in use. This is serious hardware that includes all of our standard features; Almag-35 castings, 316 stainless steel, etc. The 12V motor is also available in a 24V version and is rated well above our quoted safe working load.

Basically, its a very serious undertaking and you should consider all of your options. For the small rib in the back, a simple set of davits would do the job.

The picture below obviously shows the crane system on a powerboat but you get the basic idea.

Using a chainsaw with a sharp blade, hack the jetski into tiny bits which can then be distributed throughout the boat at your leisure.

Hope this helps,
Mike

Freetime, please let me appologize for my friend from Santa Barbara, with whom I must sympathize. On the two big Bays in the USA, a jetski is anathema to most sailors who object to their noise, the operator's blythe disregard for rules of the road and nautical etiquette, and (finally) the inevitable scantily clad companion on the back. They offend all our sensibilities, and prompt a healthy jolt of jealosy. While I reserve the .50 cal forward mount with incendiary rounds for the Poker Running Cigarette Boats, I sometimes wish I could magically conjer up a wall of 'ballast water' immediately in front of them on special occasions....

This is not to say that YOUR jetski should be subjected to chainsaw storage techniques, just THEIRS! [g]

We have some very sensible rules in Denmark. Jet skis are only allowed to operate in very limited areas, and then a minimum of 300 metres from shore. You also need a "speed boat" drivers license to operate one.
Many launch ramps do not allow launching of jetskis due to the 300 m rule.

So for once the authorities and the majority of boaters as well as all who live near to the sea have joined forces, and we have practically no jet skis in the country....

Regards

Alan

Freetime,

On reviewing my post it occurs to me that I may have been a bit too flippant with a poster asking a serious question. I surely meant no offense and apologize it I gave any.

When I lived on the hook I awoke every Sunday morning to the sound of a 2 stroke in my yard and water splashing on my windows. Since then I have had a somewhat visceral reaction to jetskis. I never resorted to lethal force but found that marshmallows fired from a wristrocket gave me a perimeter of peace of about 20í. That said, some of my best friends are jetskiers and I am sure you ride with respect.

Anyhow, donít want to send your thread off topic. Best of luck with your project.

Mike

I would have thought the 300m rule would pretty much rule out any boat ramp.

No problem, Ouer house is 20meters from the water in the lake malaren, close to stockholm and the archipelago of stockholm. We have 2 companys just around the corner with jetski sales, so im tired of jetskis myself. I donīt have a jetski.... the jetski question was mostly what size of objekt i want to lift it could be a laser dingy or a scooter.... This is just planning in my head so far.

regards

joakim

Not a good idea-it's too heavy, too awkward, has a center of gravity (weight) that is too high, and your fellow sailors will hate you. Are you really a sailing yachtsman? Sailors and jetskis get along like cats and dogs.
