Many insurance companies love you to haul out, and will subsidize 1/2 the cost of hauling before a named storm. The problem with hauling isn't so much windage (assuming you prepare by taking down furling jibs, biminis and other canvas) as the ground under the jackstands getting soft and shifting from the rains; a good marina will have staff going around checking as the storm progresses.
There is a thread somewhere on hurricane prep with contributions from many folks on all the details, hopefully the admins will resurrect it and make it a sticky as they have during past hurricane seasons.
We move our 33foot boat to a 50 foot slip and were fine during Isabel with 8 ft of surge 5 years ago. Some friends in the same marina were concerned that a boat near them with an absentee owner was not prepped, they left and anchored in Ridout Creek - appropriate name to ride out a hurricane, you thiink? - and were also fine. Now, we have friends whose house is in a fantastic hurricane hole - their dock is 360 degrees landlocked with high cliffs all around, max fetch measured in yards not hundreds of yards. Its mosquito heaven most of the summer, and our hurricane heaven when we need it ...
