There are no tides in the Mediterranean, but

That doesn't mean there are no currents. Reminiscent of Van Gogh.

Have noticed the currents can be seriously affected by air pressure too.

Aristotle supposedly died of despair for not being able to explain current dynamics in Khalki strait, though there they are mostly tidal

Well, I am impressed. Wikipedia to the rescue.

Bridge 1834
The Euripus Strait (Greek: Εύριπος[1] [ˈevripos]) is a narrow channel of water separating the Greek island of Euboea in the Aegean Sea from Boeotia in mainland Greece. The strait's principal port is Chalcis on Euboea, located at the strait's narrowest point.

The strait is subject to strong tidal currents which reverse direction approximately four times a day. Tidal flows are very weak in the Eastern Mediterranean, but the strait is a remarkable exception. Water flow peaks at about 12 km/hour, either northwards or southwards, and lesser vessels are often incapable of sailing against it. When nearing flow reversal, sailing is even more precarious because of vortex formation.

The Swiss scholar François-Alphonse Forel contributed to an understanding of the enigmatic phenomenon by his study of limnology and the discovery of seiche, where layers of water of differing temperature oscillate in thickness in a confined body of water. But the problem was solved completely only by D. Eginitis, director of the Athens Observatory, who published his conclusions in 1929.[2])

7-8 years ago, we were operating 2 ROV's in the region of St. Tropez. At about 100m water depth IIRC, we'd in excess of 3 kts current, down to within 10m of sea-bed!

A ci=couple of years ago we managed to find a shallow part of the Bay of Kotor, Montenegro. We spent ages trying to get off by putting out a kedge in the approved manner. Didn't work, so we spent the night there, self catering (always as well to be prepared!). In the morning we just floated off without further effort; no horses had been thrown overboard...

Of course there is tidal current in the med not huge like Bristol Channel but there is
movement sometimes not as noticeable as wind /swell driven surges but there is a tidal rise and fall

I've noticed changes in height of a couple of metres due to atmospheric pressure on the Spanish south coast, especially with the addition of a strong breeze. The locals are obviously aware, as the fishing boats are hauled out well above the highest strand line, irrespective of where the sea level is.

I've found the swell and current forecasts on Sea-Conditions (TESSA research project) far superior to any of the data Windy has from WAM/Wavewatch. Used it a lot this year while anchoring all around the Islas Baleares and Sardinia/Sicily. Even paid for a month to get more than 24h forecasts. Spot on every time, although sadly doesn't model the Messina strait currents - but those are here (much less precise though and not including the "Bastardi" countercurrent): http://www.correntidellostretto.it/

Another weird Med phenomena are the meteotsunamis, especially in Ciutadela, which the locals call seiche or rissaga/resaca:

On Tasmania's west coast, facing the Southern Ocean, where tides are minimal atmospherics can be the greatest driver. In Bass Strait, where the sea is shallow, relatively, the tides are much larger and there are huge races, 6 knots, at either end, on Tasmania's NW and NE corners.

Where I am in the northern Adriatic - officially classed as part of the Mediterranean - we have about a 1m tidal variation, with spring tides and/or southerly gales much more. In the extensive lagoons of NE Italy the narrow entrances can have 2-3 knots of current as large volumes of water flow in and out with the tidal changes.

The photo below shows when I ventured up to Aquileia in Italy on the Natissa river that flows into the Laguna di Grado. I moored up at the entrance to a canal into the town little thinking of the tidal state while I strolled into the center for a coffee. Returning about an hour later I was firmly aground and had to wait until the next day for the main high tide as the next diurnal rise was not high enough.

Perfect opportunity to wipe down the hull! and check the anodes.

The rest of us, well some, do this intentionally - though we might choose a lightly less public place to wipe down the hull!

Beautiful looking yacht for long term living

Thanks Jonathon, a tad too small at 31' for long term living but for my summer period soon to wind up at the end of the month, she's great.

That's a 15kg genuine NZ Rocna on the bow, by the way. :encouragement:

Ditto the Baltic Sea.

The water between Preveza and Aktio often has a two - three knot current running in it as the minimal tidal rise and fall pulls water in or out of the gulf behind it. Makes it quite interesting berthing in Cleopatra Marina as the floating pontoons sit in the current. Often catch people unaware as they try to berth, hence the marineros are to hand with a rib to help you into place when the current is running.

She looks gorgeous. You obviously look after her, the yacht, with some care, - or you are dab hand with photoshop, pretty immaculate. I had noted the Rocna, but too far away to see if she had the cast fluke - at least you know the shank is good Australian steel. The anchor looks as if the galvanising is holding up well.

The trouble with bigger is ----- the need for the bigger wallet and wallet size needs to grow geometrically with every extra foot.

Strange you should mention that, it needed re-galvanising after one year - I posted on here about it and it prompted Grant King, who then worked for Rocna, to respond and offer payment to do so. In the event it only cost €20 so not worth making a fuss about. And good to know the difficulty for the zinc to adhere had something to do the the steel hardness.

Or maybe you knew all that .... and apologies for the thread drift.

P.S.
Forgot to mention that in the photo the tidal range can be seen by the green algae on the wall ... and that location is ca. 6nm inland on the river.

Thanks, very informative. Been to Ciutadel as a tourist, never realised. The geography has something in common with Pula, where the terrible tsunami was. Also I remember way back touring a castle in Brest and seeing serious waves channelled up the rade from the west.

Had to look ( as one does ) on Google Earth. That is one serious bit of boat parking at Cleopatra Marina. Also, you may know what it is in Preveza that wishes to remain anonymous. Back to tea and toast.
