Not sure about down there, but around the NW US where we do not get Hurricanes, it is usually recomended that one take the rollerfurlled jobs off if the wind gets about 40-50 mph for an extended period of time. Saw a few last winter in my marina. South of me in Portland Or, folks are recomended to take of the jib for the winter, as they get some ugly winds coming from E Washington down the Columbia river gorge into the 70 mph range!
The pics make it look pretty ugly. I have to wonder if the storm surge is more of a problem than the wind itself. In that the surge lifts the boats, docks and all away from the piers, such that things just float away/around if that is a way to put it!

I drives me dinghy!
