Has any one seen this video of the Canadian Coast Guard in heavy weather, where they capsize one of the boats with personnel on the fly bridge?
Check out this link http://www.youtube.com/watch?v=YF_6gPlbf54
First off, its the USCG. I have seen these clips before. These boats are designed to self right, and are similar to craft used by the RNLI. The RNLI capsizes all its new craft before they go into service. They need to be able to make headway in all sorts of weather. As for crew on the Fly Bridge, you can't say for sure that they had any choice in the matter.
Catch-22 says they have a right to do anything we can't stop them from doing.
Correct it is the US Coast Guard! You are also correct in saying that the RNLI do capsize their boats to test their self-righting capabilities. However, it is done under measured conditions without personnel on board. Why put peoples lives at risk when there is a safer and more accurate method to prove a boats capabilities such as from the design stage to include test data from wave tank/flume/ and wind tunnel to the harbour trials which we are all familiar with. The site that was chosen for this video shot was in shallow water because of the breaking waves, although I could not be sure of any damage to the mast. Data acquisition in these conditions would also be difficult to accurately record. The next point is the quality of the video itself. If these two boats were on a proper test run, surely high grade recording facilities would have been set up ashore and perhaps from the air, rather than a hand held, low resolution video! I suspect it was a chance encounter, which proved to be a little livelier than was planned! Can you see our Naval authorities permitting such a test at sea? I don’t think so – HSE would have a field day!
The aluminum 47 foot lifeboats used by the both the USCG and the Canadian Coast Guard. The exercise was probably more about crew training than testing the boat. Some similar pics at http://morrobayphotos.com/uscg/USCG%20MLB%20Action/.
I have photos of eithne doing some high speed turns that would make anyone on the bridge think she is about to capsize...but.....
I have a photo of Eithne doing a forced roll during sea trials, before hand over to the Navy! It was induced by puting her stabilizers in to reverse at speed.
Having been on board for the sea trials I would love to see that picture , and going from full ahead to full astern was a sight to see . Clear the after deck .

Hi Laners,
I'll scan the photo for you! I have a problem attaching photos to the site but I'll work on it! How long were you on the Eithne? I was there for three years!
If someone is going to criticise the seamanship of the USCG, I presume they have pretty impressive credentials of their own to base that on?
Absolutely, glass houses and all. personaly I cant say either way knowing nothing about them but as for safer ways to test things. That is true to a point but in honesty the only real way to know wether or not something is capable of surviving certain conditions is to place the object within the required conditions.
Its a victimless crime, like punching someone in the dark.

Yellowjacket and G2, I understand your points and where you are coming from! However, being involved in R&D, any approved testing bodies or standards authorities would never, never put peoples lives at risk in this way, to prove a vessels capability! Performance analysis and integration of the various components is considered right from the conceptual stage, through the design and in to the final build. In addition there is enough modelling software available to examine any test movements, stresses or strains on any shape or size of hull or superstructure. The days of building a vessel and putting her in to the water to ‘see what happens’ is long and truly gone! Certainly a vessel has to be sea trailed, but only to a ‘certain point’! Not to destruction. Data can be acquired to this ‘certain point’ and projected mathematically or scientifically to the destruction stage if necessary! As I said in a previous post, Tank testing would be the norm for a new design of hull or vessel. Inclination and stability tests for example, are standard mandatory practice during harbour trials and are strictly regulated by recognised bodies such as DCMNR, Lloyds DNV and others. So again I ask, what is to be proved by putting a crew on to an open bridge deck and to capsize the vessel in the uncontrolled manner that this video clearly shows? Is it to see who might survive? Sorry guys, the gung-ho bravado bit doesn’t work for me!
I'm with test pilot on this one. I have seen the tests on RNLI craft in Poole, and it is a very controlled affair. One must assume that the boats in the clip had no option but to run along the crest, and risk capsizing. However training should also be realistic, without putting crews at unnecessary risk.

Thanks Goldie! Another enlightened being on this planet!
