Watch Your Back
How do I move a 1,000 lb. Jet Ski on the sand near the waterline? It's pretty simple.
Here is a quick review of what I do to pivot the Rescue Water Craft. I have watched many people over the years who have not been mentored properly in how to move a boat without strain or scooping the jet pump cover into the sand.
Maybe this advice will help you?
Don't forget this: Sand is sandpaper. The more you ground your RWC and the more you drive up on the sand you are going to damage the keel. Sometimes it is significant. Oftentimes with sand groundings the sand is a light cover, below the surface are heavier hard objects that hull can come in contact with such as rocks, cobble or shell.
These boats are not made for that and Coxswains should use due caution because of breaking motor mounts, ruining the bottom hull and leaving an asset unusable or out of service for repairs. Our Kawasaki Jet Ski™ hull is fiberglass/gelcoat construction.
If you have a Yamaha WaveRunner™ that hull is constructed with NanoXcel™ and cannot take hard repeated groundings without rendering the hull with severe damages. We see lot of hull damages from boaters not knowing their boat!
As your online mentor I would ask you to start thinking, open your attitude and park your ego, and learn to define what is taking place. So, I encourage you to look at physics. What does this mean?
Dry curb weight of the craft. Do you know what it is?
It is 932.7 lb. (dry), (422.74 kg)
This RWC model is holding a full fuel tank of 20.6 gallons. Gasoline weighs roughly 6.3 pounds per gallon, depending on the density of the FUEL. If using the metric system, the approximate mass of gasoline is 2.8 to 2.9 kilograms, depending on its density. (X 20 Gallons, x 77.97 liters).
The forward hatch has 2 pelican cases and lines fully loaded. Boat can hold up to 50lbs. stowage. (22.67 kg)
STRUCTURE OF REALITY
So, what I want you to do is look at mass weight, weight distribution and where the most centered mass is. it’s not at the waterline aft, it’s at the waterline forward. The sand is soft, the boat will ground in.
It’s good to put the craft angle on a list off the centerline like you so I do in the video so you can star the initial pivot. Also remember, don’t stop moving, keep the forward motion going (back to physics).
Make sure there are no other PWC's or objects in the rotational pivot point path from bow to stern.
Tidal changes make a grounded boat difficult to get back to the waterline by yourself. This can help in those situations.
This works well, it's easy and any senior citizen like myself can do it. 🙂
I've been moving thousands of Jet Skis since 1979, I think I got this covered lol
What is your goal for moving a grounded craft? To not cause harm to your back, or strain. To be able in some situations to move a Rescue Water Craft without asking for help, especially if there is none.
