Heck! No, that's Olga 'Forte' Polizzi's gaff. So do you run boats out of there? The crew of the classic sloop (or what ever it was?) had a moan at my kids a while back for sailing too near to them as they were trying to pick up their mooring.
That may have been me............I dont recall it though, so I might have been away keelboat racing at the time!
What's that got to do with S/S prop advise anyhows??? (probably a private message thing hey?)
