Sea of Marmara
An online cruising guide for yachts sailing around the Sea of Marmara in Turkey.
The Sea of Marmara (Turkish: Marmara Denizi, Greek: Θάλασσα του Μαρμαρά or Προποντίς, Bulgarian: Мраморно море,Hungarian: Márvány-tenger (Marble sea)), also known as the Sea of Marmora or the Marmara Sea, and in the context of classical antiquity as Propontis (Greek: Προποντίς), is the inland sea that connects the Black Sea to the Aegean Sea, thus separating the Asian part of Turkey from its European part. The Bosphorus strait connects it to the Black Sea and the Dardanelles strait to the Aegean. The former also separates Istanbul into its Asian side and European side. The Sea has an area of 11,350 km2 and is about 150 nM (280 km) long and 43 nM (80 km) wide.
The salinity of the sea averages about 22 parts per thousand, which is slightly greater than that of the Black Sea but only about two-thirds that of the oceans. However, sea-bottom waters are much more saline, averaging salinities of around 38 parts per thousand — similar to that of the Mediterranean Sea. This high-density saline water, like that of the Black Sea itself, does not migrate to the surface. Water from the Granicus, Susurluk, Biga and Gonen Rivers also reduces the salinity of the sea, though with less influence than on the Black Sea. Almost all of these rivers flow from Anatolia: very little land in Thrace drains southward.
There are two major island groups known as the Prince's and Marmara islands. The latter group is rich in sources of marble and gives the sea its name (Greek marmaro, marble). A notable island located in this sea is İmralı, where Abdullah Öcalan is imprisoned.

Climate & Weather
The Sea of Marmara is an enclosed sea and one may be deceived into complacency, thinking that it is an easy sea to transit. The fact is that it can develop very short choppy seas which if you are going against them make a very uncomfortable and wet ride. Also the weather here can change rather abruptly and violent thunderstorms are fairly frequent during the summer resulting in very bad visibility in these waters full of large commercial shipping.
Note, however, that during the close season for the fishing boats (May to September), many of the commercial harbours around the Sea of Marmara are filled to bursting with laid up trawlers and purse seiners. It can be difficult if not impossible to find space to moor in them during these months and a yacht is well advised to head for harbours which cater for cruising yachts, of which there are a number around the shores.
