Someone once said that the day you stop being scared of the sea is the day you die.  You are very vulnerable in a small craft - of any sort.

Just thought I'd add that comment to raise the vibes .....

Totally endorse what Ian has just written.
All our craft had buoyancy in the side bodies to give stability and as much as physically possible at the rear.
Osprey 5 had built in buoyancy compartments in the planing surfaces.

The RNLI and the other independant rescue organisations are superb and deserve all our support.

This event does illustrate some important points which were discussed in the Tech Corner article on off-cushion stability. It's important that a craft will float reasonably level and stable when swamped - this one did not, you can see how easily the RNLI guys rolled it over. Thats because it did not have enough bouyancy located far enough out towards the gunwales. This is a particular issue in craft with wet plenums, where a dry plenum is used you see much better intrinsic off-cushion roll stability.

If the swamped roll stability is poor, it'll tip you out and you won't be able to get back on the hull, upturned or not, as it'll continue to roll over each time you try. I can tell you its a huge relief to be out of the water and sitting on a floating platform whilst waiting for rescue, rather than in the water.

The good news is that it would be very easy to check your own craft, to see if it has floatation material fitted in the plenum. If it does not, then with a little ingenuity it is relatively easy to fit some. So go and check! Anyone with a wet plenum craft should be doing so.

Just had the info on what happened.
4 craft went out fully equipped with all the safety gear and experienced operators.
Good weather and moderate seas. 3 craft passed a point with no drama but craft 4 got caught between 2 waves and dropped a considerable depth in between and the next wave strike the craft high up and turned  it over.
All damage was caused after the incident by waves and recovery.
RNLI were perfectly fine about the incident and the knowledge and equipment carried by all concerned.

The bow appeared to be intact prior to it being lifted


EDIT: Oooops - just read your comment Mr. Nick  :D

It was one of the Museum lads who is OK.
My guess would be insufficient strengthening of the lower hull at the bow.
This more than likely bowed right in with the force of a strong wave causing it to tear off at the upper attachment.
Once caved in it would be game over.

I would have thought recovering the HC, regardless of its state, would prevent further calls to the Emergency Services in the event it was spotted drifting out at sea.

A good reason to support the RNLI, they even recovered the HC!!!

That last picture does not show the bow torn off as in the newspaper picture, so looks like it was torn off during recovery, but as you say, they certainly went the full monty trying to help the owner.
I was once hit by a rogue wave, (Off Abersoc, Wales) which came from the SHORE, and hit a shore bound wave right under my speed boat. This created a wave  about 7 feet high, and when  I landed, (about three minutes later,)  it broke the underside of the boat.. I limped back and GRP repaired it at home! Well times were hard! ::)

Recovery pics are on FB HERE

For no-FB users, some pix:


Looks like the duct damage was probably caused by banging on rocks, etc.





Craft isn't much use as a lifeboat if it only "floats" under the surface!  I'm actually surprised the LB crew got into the water just to  recover a craft- that's above and beyond - I certainly wouldn't do it.  Whoever the craft owner was - they were very lucky to get ashore!

Craft was a stretched osprey.

Don't think anyone was hurt - craft looks a bit small for single operation off the Needles ?
