For those members sailing west coast of Turkey, Chris Haire, HPO Izmir has passed on the following information:
There is continued talk about a new marina in Karsiyaka but that's as far as it goes. On the southern side of the bay at the western border of the city there is a boutique marina - formerly known as Levent marina - but this does not cater for visiting yachts - especially as only Turkish spoken by the staff! All of which tends to isolate the city from yacht traffic. Nearer the mouth of the bay, there are places on the Karaburun peninsular and at Foca on the other side (always crowded). There are also anchorages in the south western part of the bay but military areas are to be avoided.
Best place to stop and see Izmir is at Teos Marina Sigacik where a 40 minute bus ride takes you to the city.
