Will my boat journey be rough?

[Danni B]

Hi there

I'm not quite sure how to read the windfinder. I thought the wave period seconds closer together were calmer seas absolutely further apart were rougher!? Am I correct in thinking that a 2 meter wave at 10-11 seconds will be rough?
Thanks in advance. P.s New to this group

I forgot to add that this will be on a large condor boat

EDIT: How large is large? If you mean Condor Ferries then you won't even notice the seastate.

I wouldn't think twice about going out in that forecast other than lack of wind. Have a read up on Seastate, your app shows seastate "slight".

Sea state - Wikipedia

As Baggy says. We too would absolutely sail on that forecast, though we’d prefer a light-ish wind to be blowing in a good direction. 10kn is a fine sailing breeze for us, 4 in the later part of the day is more of a challenge.

Though the sea state scale may be about right for open water, around the UK in both english channel or bristol channel (and no doubt other areas) one get Channel Chop with steep waves fairly close together. There I would regard 1.5m as effectively moderate and expect a bouncy tiring passage particularly if heading to windward.

Long ago on our first return from Scilly, the Navigator was very concerned about predicted 2m waves in the slow build up to a forthcoming storm. But as we hurried east blown by the usual west country westerly she expressed astonishment that we were merely going up and down slowly. That was because we were in open water out of the Channels, thus in a situation new to us.

On that trip we were heading for Padstow, but if going round the Lizard peninsula heading for Falmouth 2m waves would spill our teas and have us rolling 30 degrees unless waves were dead astern

In the Solent, with wind over tide, 1.1m waves are just plain nasty. OTOH, out in the channel, with wind and tide together, they're barely noticeable.

I went through so many weather online predictors but finally stayed with Windguru .... its what we use when manoeuvring ships .... I know it gets its info from same places as others + the unnofficial input of amateur stations ... but its presentation of data is one of the best IMHO ...

10-11 second period is quite long, more of a swell than waves. Go out and see, if you don't like it head back in. Nothing wrong with doing that.

Predict wind is free and has a seastate map.

Rough is a purely subjective term.

 

[chris-s]

depending on what direction you are heading, don’t think that was mentioned, things can be quite different
