There is or was last year a very rickety jetty at aksazlar beach, just deep enough in places to moor a shallow draft boat to, a couple of the calis water taxis came in to it as there was a wedding there, one ferried in the bride. Further round, out to sea, sorry Don't know name of beach, alesta yachting had a jetty with water & electric, it's one of the bays the Orange dolmus goes to. Water cleaner than aksazlar. Hillside also have a jetty, but you will certainly be charged to tie up here. Towards gocek, there is a jetty at gunuklu (sorry about spelling), called something like the bay beach club, again sure you would pay to dock here.
