Surfriding Stress Testing a Hull

[zimmy]

Found this interesting video!

Anyone ever done a drop test on a reinforced hull or a custom setup to date?

wow, I wanted to see him let off the throttle out there with no nose on the boat, seems it would have plowed under at that point?

wish our hulls had the space for that reincorcing and foam without weight a ton.
just no room for all that foam

Glastron was doing this 40 years ago in James Bond films.

They let off the throttle and were plowing at one point so I don't think it would matter. They did strategically place that cut though so it might be different scene if it was a foot or two more towards the back and also if the drivetrain was in it at the time. Those engines would have come thru the bottom in that case. Still a very good test of the strength of the hull but in the real world, the weight of the engines would drastically change the outcome, even from a much lower height.

Aren't some of the Seadoo models built with a layer of foam sandwiched under the engine cradle area? I read somewhere they had issues with water intrusion and layer separation in one of their models.

How much $$ do you guys think went into that little demo? $50K or more like $200k?

i cut up a yamaha SUV 1200 and it had foam between 2 layers of thick ass glass. what a job that was

I only chopped up one hull, I throw them away whole now. I itch just thinking about it.

I thought you just drug it behind a truck in a parking lot

Now that's impressive!

throw it in the truck, take it to the dump...get a good running start in reverse then pin the brakes and usually they will shoot right out into the pile lol


doesnt work as well with boats on trailers tho

The foam core seems like a good option for strength. It surprises me that SJs have issues with the rear ends cracking from rolling, I would have thought with a "foam core" they would be quite strong.
