Do you mean dry storage as in "on the hard" as as in "in a shed"?
If the latter, you will be hard pressed to find anything, but there are plenty of places to haul out for two months. Last year Yachtmarine in Marmaris did a reasonably priced two months on the hard deal, but there are other places including Yacht Lift near Bodrum. Last time I sailed to Bozburun I noticed that the boat building area in the bay to the south east now has a long jetty and had yachts both alongside and hauled out. I have also had my 45 foot boat hauled out at one of the boatyards in Fethiye, at the end of the bay.
