On my walk round Hythe marina this AM noticed thin ice skin formed in some of the backwater channels.
Brrr, sea-water freezing - that’s gotta be cold!

Emsworth used to do that a lot, but it did have fresh water flowing in and the cill would keep a smaller quantity of water in at low tides. Certainly surprised me the first time I saw it.

Depends on where you are, for some of us it's normal 
. This is our club marina in Helsinki a few days ago, with a couple of cross-country skiers passing. Of course the Gulf of Finland is not as salty as the Atlantic. Today's quite nice out, sunny and about -15ºC.

Seen the same at Mercury (probably best part of 30 years ago). We were lent a pile mooring off the marina and use of a mate's dinghy space in the marina. We sailed to Camber Dock one weekend, noting that the deck froze on the shady side when we were half way there and the hatch froze shut overnight. Sailed back on the Sunday, moored the boat and hopped in the dinghy to row ashore only to find the marina frozen. The GRP dinghy wasn't heavy enough to break the ice when we rammed it so had to use an oar to smash through to the pontoon.

Saimg (motoring) through thin ice makes an extraordinary sound on a grp boat. You half expect to have worn the gelcoat off.

Regular winter problem up here biggest danger is black ice forming on pontoon and side decks making access difficult if not impossible

Tidemill Yacht Harbour is pretty much frozen over, with settled snow on top in some areas. This was yesterday when I went to check on the boat.

I walked out to these islands a few winters ago. Ice went beyond them as far as I could see, but didn't feel comfortable going out further, although locals were out there with their skis.
I then walked over to the corner I have marked by a red cross and there was a small area being kept free of ice by a big pump and locals were jumping in in their speedos, after getting out of the sauna

Just had a look at Chatham Marina from an elevated cctv and all the boats are white. No ice seemed to be present.

Walking down the pontoon to check the boat today I noticed that ice had formed in the empty berths. It was bitterly cold...I didn't stay long.

We recently had a thread addressing the problem of wearing crampons on a teak deck!

In more northern latitudes the ice brings heavier restrictions, like minimum required ice class and dead weight. Thick ice can also bring opportunities.
The "Ice conditions" reveals 15–30 cm thick fast ice in the eastern Gulf of Finland, including Helsinki, Jan. 12 (see #8). The latest "Baltic Ice Chart" covers a larger area.
On the other hand, there's a table giving the load-bearing capacity for ice of given thickness. As an example, 100 cm thick solid hard 'steel ice' allows a combination vehicle with a maximum weight of 48 tons (metric).

In the early seventies I saw Chichester Harbour with a skin of ice about 20mm thick covering its surface as far South as East Head. It wouldn’t’ bear my weight but I tasted it and it was fresh water ice. As the tide receded it left this film of ice covering all the sand and mud banks. Iirc it was a very still cloudless day and the sun glinting on the landscape of ice was quite surreal.

Inverkip Marina froze over at least once every winter while I berthed there. The fresh water input from the Kip burn floats on top of the seawater and freezes.

There was fresh water ice lying on the mud this morning in Conyer.

Off thread so apologies
May i ask if that fresh water has much of an effect on the fouling of the hull. IE. does it reduce it down much?
Or does it stay too near the top to do any good?

There was a TV series " Ice Road Truckers" where they were taking loads up to Alaskan oil fields etc. The sound of the ice cracking as the lorries drove over it- 1 metre thick- did sound a bit daunting. Not sure that i would really want to take 48 tonnes on it. I know it was exaggerated for the media, but all the same

The Clyde generally is a low fouling area, but I think the freshwater input at Kip did reduce it even further. I could always go 2 years between antifouling.

Even commercial shipping takes a break in some areas where frozen waters are usual in winter. The photo shows the bulk carrier Baie Comeau frozen in for the winter at Midland, Ontario. An ice breaker will open a channel for her to leave near the end of March, but that will quickly freeze over again. Launch day at our sailing club will not be until early May (COVID willing). Two years ago there was still ice floating in the bay on our first day out.
