Re: Another tragedy on the water

That formula is crazy, because hull type makes a huge difference....v hull to Catamaran??? A incline test is the only reliable experiment........CaptG

Re: Another tragedy on the water

Just looking at some boats tells you that they are more likely than others to capsize. It would be a complicated formula to get an accurate "rating" of stability due to hull shape, type of wave, weight distribution, and variable things like loads and water, fuel, etc. An actual physical test, as Gary is saying, seems the only real way, considering the potential danger to people. Get some weights, go out and see how much weight it takes to capsize the boat under various sea conditions. Cars are crash tested to rate safety and perhaps boats should also have a similar procedure.

The capsize formula works for the most part albeit it doesn't take into account the center of gravity. So theoretically adding more people makes the boat more stable based on beam/weight ratio. However, when the vanishing stability and beam/length ratio are calculated in then it becomes apparent this boat was overloaded. Even running the stock numbers supplied by the manufacturer, the Silverton 34 calculates as an unstable hull, without passengers, fuel etc.

They raised it - It will be interesting to hear the outcome of the investigation.

Re: Another tragedy on the water

Wouldn't the boat feel weird loaded like that?
I suspect it could be a all or nothing thing but one would think that their would be handling issues that would for-warn of a problem.

Re: Another tragedy on the water

They raised the boat and towed it into a marina next to my yacht club.

Re: calls for more regulation.

Coming from the aviation world where everything is regulated into a massive nightmare, I can tell you that no amount of regulation in the world fixes stupid. You'll find 10,000+ hour pilots with the highest ratings overloading airplanes, flying into ice, t-storms, etc. The amount of work it takes to be rated is pretty high and people still do stupid crap to get themselves (and others, unfortunately) killed. They are typically the same types you see killing themselves on boats, usually arrogant and unwilling to think or do their homework. No amount of training or regulation will filter that out.

What DOES work is community awareness and activity. If you see someone doing something stupid, then tell them. I highly doubt no one saw these guys going out there on an overloaded boat and didn't think "man that looks risky". If the community regulates itself, it's far more effective than when the government comes rushing in.

Please be careful what you wish for. Any pilot with more than a few hundred hours will tell you that the FAA regulations introduce headaches, increase costs, and limits innovation. Bringing similar attention on the boating community would be much more headache than I believe you'd want.

Here's an opinion article from Soundings regarding the capsizing of the 34 Silverton at Oyster Bay NY.
