‘Easy Rider design a death trap
Almost half the boats built to the same design as the Easy Rider have sunk, sparking an urgent safety call for the remaining vessels operating.
The Easy Rider, which capsized off Stewart Island in March with the loss of eight lives, has been found to have stability issues, the Transport Accident Investigation Commission says.
….The Commission believes there may be at least five boats of nine boats of the same design built nearly 40 years ago still in service…’
Assuming these clowns are right, and the design is faulty, then it’s only taken the sinking of half the boats and forty years to prompt an “urgent” safety call! But I smell a rat–if for commercial use, the boats should have been built to survey–and one of the survey requirements is a stability test or at least stability calculations. So what happened?
Leftists/”progressives”/socialists are not welcome here. Pay for your own soapbox.

The same thing that is happening with leaky homes. The Officials did not do their job and are passing the buck onto someone else.

Kinda fits, doesn’t it? These bastards are never held personally responsible.
Any boat that is overloaded has “stability problems”. Duh
OWENGA CLASS: unstable when heavily loaded.
Nooooooo…. Really?/sarc :rant
I assume (from the wording of the article) that what the Commission is saying is that the hull design is inherently unstable. I’ve worked on crayboats which have been very overloaded, in rough weather too but the hull designs were excellent, and with expert handling there was never a problem.
The Easy Rider was believed to be built in about 1975 to the Owenga design for use in the Chatham Islands fisheries.
What are the typical conditions encountered in the Chathams, and how do they compare with Stewart Island?, where did the Owenga design originate, and what conditions were they designed for?
Some skippers need to have the difference between form stability and initial stability explained to them.
Lots of tinnies, for example are stable enough for a person to stand on the gunwale without the boat capsizing, but one past a certain angle the hulls will flip like a pancake on speed. The owners are convinced they have a “stable” boat. On the other hand, plenty of traditional designs feel unstable, because they roll a gunwale under easily, but they’re almost impossible to capsize. The Chamberlain dory is an excellent example of the latter. Designed over a 100 years ago for unbelievably rough waters, it feels “tippy” as hell. But I never could get mine to do more than slop a cupful of water aboard.
They also don’t know about the free fluid effect and how it affects stability.
In 1947 my father was an Engineer on a Liberty Ship that was in ballast and the ballast shifted in a hurricane.
The ship survived and the way liberties were ballasted was changed as a result. Liberty ships had a bad reputation at that time because a number had come to grief but they were excellent and sea worthy vessels as their longevity proved.
Didn’t they have problems with the welds early on, Andrei?
Some of the first all welded hulls had problems with Hydrogen embrittlement early on,but it’s understandable considering that Arc welding was still a fairly new technology then.Once the problem was solved it went flawlessly afterward.
Henry Kaiser is one of my heros,by the time the last Liberty slipped down the ways in 1944 they were finishing a complete hull every 4-1/2 days.
My boss went over from Brooklyn,Ny to Hamburg,Germany in 1949 as an oiler on a Liberty,he was all of 17 years old at the time.Imagine todays 17y/o kids doing the same

Yes – they needed ships and they built them and overcame setbacks without navel gazing.
If we were like them Christchurch would be rebuilt already.
Yes indeed!
“..he was all of 17 years old at the time.Imagine todays 17y/o kids doing the same”
No, I can’t.
That’s a cool link.
You don’t leave school until you are nineteen these days
And if you want an apprentiship (after 13 years of school) you have to do a pre- apprenticeship thingy at polytech with no guarantee of an apprenticeship to follow but a student loan no doubt to pay back.
People are not even starting work until they are in their early to mid twenties in these enlightened times.
Yet there were 22 year-olds skippering clipper ships in the 1800’s….and 19 year-old officers leading men in WW1.
And we have a 17 y/o hire on at the shop rightnow that was never taught to read a tape measure or clock dial
What we have now is males inhabiting a state of perpetual adolescence.
……… but it is my second time round.
