Hurricane prep is 110% site specific. I’m extremely fortunate in that my marina is probably one of the best hurricane holes on this part of the Gulf Coast. Surrounded by structures on all sides ranging from 2 story to mid rise condos for some wind protection. Complete wave protection due to canal access to lake with 2 opposing 90 degree bends. The marina took a 13’ surge during Katrina, lost 2 boats – one came down on a piling, the other torpedoed by a center console that some yahoo dropped off immediately before the storm and secured with poly ski rope.
Top fuel and water tanks if time, leave the normal dock lines in place, add dedicated storm lines chained to steel/concrete structural pier features and tension, move all tophamper below and/or off the boat, batteries charged, install and secure rope boarding ladder, cross fingers, go home (or go away, depending on the storm).
