Kroeslin boasts a almost brand new marina, built with every possible convenience. There is an abundance of decent, full length pontoons (red and green tags are used to show which are free and which are reserved), and a good chandlery [rare around here - make the most of it]. Showers and loos are to a high standard and kept spotless. Winter storage is available in both a cold hall and a heated hall. There is a boat lift.
Kroeslin lies in the Peenestrom - a channel which runs from the Stettiner Haf to the Greifswalder Bodden. It is the channel between the German mainland and the island of Usedom, which is split between Poland and Germany.
Coming from the south, the channel is very narrow in parts, and not very deep, but buoys are being laid all the way down (well over 100 of them!). There are two lifting bridges, one at Wolgast, and the other at Zecherin. They open only fairly briefly a few times a day, so you have to time your passage to the opening of the bridges.
Coming from the north - that is, the Greifswalder Bodden - the channels are again very narrow, but well marked. The old V2 tracking towers are a good landmark!

Old V2 tracking station in the Griefswalder Bodden. Notice the fishing pots which are also a hazard in this area.
The harbour is at the top end of the Peenestrom, directly opposite Peenemunde, where the V2 rocket was developed in the last war. The entrance is very straightforward: the link below gives you a chart of the channel and marina.

Inside Kroeslin marina
The town itself is picturesque, but there is little in the way of shops for necessities. A ferry runs across to Peenumunde every few hours: the museum there is well worth a visit. Again, little or nothing in the way of shops.
Excellent view of the town and marina. You can also take a wonder across and have a look at the old V2 development site at Peenemunde.

Kroeslin church. The spire can be seen from some distance as you come along the Peenestrom.
