Wave height 10m period 11 seconds

Just curious how that would be in a typical off shore sail boat.
That is the conditions off Cornwall tonight.
20 seconds seems like the boat might juat ride up and down the wave, but I am no expert.

Would the boat have windows on the hull?

All good until they start breaking. Fearsome and quite a few ships and fishing boats out there.

I think tonight,s trip out of cornwall in a typical recreational sail boat would start with the sum of all fears and end deadly should SAR fail to pick you up quickly .

When you make it to the helicopter you will do it with a bronze medal in your shorts ;-)

No pun intended , just joking ;-)))

Like the last scene in that film the perfect storm

It’s 10.9s, period is one full cycle of the wave, from trough to next trough, for example. Hence, in this prediction, every 10.9 seconds you would go from one part of the wave, to the same point on the next wave in 10.9s, having gone through a height difference of 33.8 feet. If the frequency was long, it could be as you think.

Probably a brown trouser time, while reevaluating your relationship with God.

That sounds utterly horrific. Hopefully no one has been caught out

We’re inside the lock at Sutton Harbour and it’s pretty rough here. The wine bottle fell off the table while we were heeled.
We’re obviously alongside and tied on.

There were plenty of folk still out there at about 19.30, when it really started to build here. See attached.
French fisherman still at it, a few showing as "dodging" on AIS.

Local NCI station showed 50-55, gusts to 88mph. But from NW, so in S Cornwall not as bad as it might have been?

Seems to have tracked thru quickly? Appears to be dropping here already...

hope it was a screwcap!

Sailing Nahoa did a good coverage of wave hight vs period in

My partner has cat like reflexes and caught it. I have since emptied it for safety purposes.

Do some more/better research before you set sail across an ocean; a very moderate 3m swell running at a nine second interval is not my idea of the 'sweet spot'.

The bulk carrier Luyang Smooth looks to be having trouble near that location. Speed 3 kts and 180 degrees off course ?

A floating glass light bulb will see off a hurricane. In fact the Japanese still use glass floats for fish nets. It depends on the boat and whether you really wish to be onboard. It's always been said the crew will give up before the boat.

Very true we say 'The weakest thing on the boat is you' and Oh so true

I remember being offshore in a dive support boat in those sort of waves. All bets are off for yachts in those conditions. Waves as high as masts on 25 to 30’ yachts….. maybe if you can keep it straight but waves like that are so steep I think you’d be quickly be either tripping over your keel or engulfed in a breaking top.
