I am going to ship my 35' Oday to a boatyard on the Miami River later this year. The boatyard doesn't provide any temporary berths and also I don't relish having to wait for all those bridges on the river. So I was thinking of rather than stepping the mast after launch, I would motor under all those bridges with the mast down into Biscayne Bay to a marina where I could put up for a few days and get things ship shape before beginning my cruise to the Caribbean.I've been trying to find a boatyard or marina that provides transient slips and that has a crane capable of stepping a 47' mast. So far searches of the internet and Waterway Guides have proved fruitless. Does anyone know of one around Miami that is not on the Miami river? Thanks
