Boat Capsize Evidence

[Submarine Tom]

Sachi,

Do you have any pictures or has your thread been hi-jacked?

"Passengers crowded to one side" is not colloquial and has specific meaning in various stability criteria. It normally includes passenger weight in areas designed to accommodate people, whether sitting or standing, and is not the same for all types of vessels. You would have to check the applicable criteria to determine if passenger weight on the gunwale is a consideration.

"..My 11 ft aluminium dinghy/tender would capsize with 3 people on the gunwale, it probably would with 2...me and my mates on the gunwale would be passengers crowded to one side.."

Is your 11ft dinghy designed to have 2 or 3 poeple on one side? When you bought it, did the brochure say...."look great, you can even have 2 or 3 crew sat on the gunwales"..or did it say something else, or nothing at all?

Note, these are "technically" not passengers since this implies they are paying for the pleasure of being transported on your dinghy - incidentally a minimum of 12 is required to be called a 'passenger' boat too.

I agree with Ad Hock and Paul. A boat is designed with a certain load in mind, but not all the load on the one side.

We had a similar scenario where a pleasure 'boat' capsized. There never was a problem until they decided to have a strip show on the upper deck. So when the stripper started her act, the bunch of sheep all shifted to the one side - which I assume was the front side - of the stripper that is - which was on the side of the vessel - and it toppled over. You have to realize that South Africans have never seen a naked woman before and it stands to reason that they would lose all sense of logic. Ok just until they hit the water.

Can only be humans doing such stupid things, and we're supposed to be a spesies capable of thinking. I say next time THINK before you get aboard with a bunch of idiots.

my boat is a double Decker one, with seating capacity of 80 people. Its a fiber boat. It was capsized while taking a turn in lake while on full capacity. It is suspected that there is a design failure and people want to sue the company.

I do not know why but I missed the second part of your post Sachi.
I apologize, it is a good question
Cheers

my boat is a double Decker one, with seating capacity of 80 people.

The other Q is, how many people were actually on the upper deck ? I can hardly think it sensable to have the majority people on the upper level.

Since there is SEATING for 80 people, were they SEATED

Kinda makes me think of these phiolamon taxi's here. There is seating for 11 people, but 22 gets injured when there is an accident. No, it's not overloading in SA, neither is it the driver's fault, it's the vehicle that is not roadworthy

Valid point. Passemgers rarely hike out over the rail on a tour boat!

No response from Sachi. Another hi-jacked thread. Of course you guys haven't even noticed. Carry on...

[Fanie]

The thread is right on topic imo. Sachi may have left because he didn't hear what he wanted to hear.

man your hilarious

Yes well, according to the news report they were ALL wearing life jackets (remember it's LAW here now). Not sure how a strip show goes where all are strapped into their life jackets. I've been to a strip show before (can't remember the colour of her hair or if she had any) and I've warn a life jacket also, I can just imagine it is going to be kinky.

One of my friends is currently building himself a similar party boat. He was going to make it 4m wide, and it's 12m long. Since I had to draw the structure for him, I told him 4m is too narrow, exactly for this reason. If someone say check the fish the whole bunch is going to storm the side. 6m minimum, I still think it could be wider, but the real solution would be to get more than one stripper at a time

[ancient kayaker]

Then the boats on either side will capsize

[Sachi]

My boat 14 m in lenght with 4 meter beam, 1 m draft and 15 ton displacement. It is made of fibre and a double decker. total weight 6 tons.

I want to investigate the following

1. How to analyse a suspected design failure
2. what is the maximum degree that the boat can turn
3. What are the requirements for an FRP fibre that used in boat especially plesure boats
4. What are the regulations for pleasure boats
4. Any other useful information

Please help me with books, astm, ISO or any other documents in this regard

thanks in advance

14x4m boat licenced for 80 passengers? Hm... Who issued the licence, Marine Department?

Just leave the country and let anyone that wishes to sue get on with it. However you approach this, you will end up bankrupt (even if you are found to be blameless) so it's quicker, cheaper and emotionally simpler to turn yourself into ether.
