By my reckoning, slack is closer to 0930 on Saturday (about 3hrs 50 after HW St Helier), and for the following 5hrs the lug/inlet on the west side would be nicely in the lee of the tide.

Drawing on a combination of experience and from whipping my tidal diamonds out to check, I can say that the tide around Casquettes is no less well behaved than it is around Alderney. "Slack" water will be a fleeting experience that moves around during a period between 2 and 4 hours after high or low waters, depending on which bit of seabed you are over at the time.

Having spent 18 months working with the tide in a couple of square miles round here, I would suggest we arrive as early as we think we can and make some careful observations. Allowing for time on task.

Edit: Not a criticism K, just thinking we would be better to arrive early and wait a bit than arrive in the middle of the window and find it closing.

I bow to your tidal knowledge oh wise one

I have a feeling there may not be much to see there. 10 mins will be enough even allowing time to buy the T-shirt. It looks from the photos that the courtyard area may be walled in with gates at either end.

The 7th edition of the "Beneteau Pilote Cotier" has some information for those visiting the Casquets. It suggests anchoring in the little inlet immediately south of the lighthouse in 6-7m of water at MLWS. By the way, have we decided what day we're going? Sunday's looking a better bet judging by the forecast.

It's looking like I may have trouble getting up due to the other half's work committments on Saturday. If I do come it'll probably be Saturday pm, so a Sunday visit would be better option for me.

I was thinking along the same lines as Malthouse re tides, by my calculations 07.30ish the NE stream should start to slow down and begin backing round as it gets toward slack water. By slack water I mean 2.5 knots obviously

I was thinking get there early so we can get in at the first opportunity. Although sheltered from the SW stream I thought it better overall to be in and out before it picks up too much speed.

Having said that, when I was in there during the ribnet cruise, iirc the time was about 12.00 local. According to my plotter the SW stream should have been running at around 9.5 knots at the time Not sure how much I trust that as I don't remember seeing anything like that!

So it looks like sunday's are best bet then, although the forecast is getting worse all the time so we'll have to wait and see if it happens at all

Windfinder are giving 7 to 12 kn for Sunday at the time of writing.

The synoptic chart shows a great big fat high pressure the size of Europe poised just west of us, if that does not end up sat on top of us for the weekend I would be surprised.

Based my theories on these. Tidal diamonds are a bit too vague for this kind of exercise IMHO

Ahh...I was using a diamond on my plotter that was kind of WNW of Burhou thinking it would be very similar to Casquets. Clearly a hideous error on my part

Yes they are.
