Check with your dock neighbors first and foremost. I've seen lots of folks "haul out" and put their boat right into harm's way. If where she ends up on the hard is not much higher than the water level, then you're not necessarily gaining anything, and definitely not if it comes to storm surge. Now, if she can move 100' up, different story, of course. I know lots of folks that actually move "out" instead of in. A lot depends on your particular situation.
I mainly want to remind you (and everyone else), to remove your Biminis & Dodgers, along with everything else that's topside that you can. Those top frames are definitely not made to withstand that kind of beating. If you stay in the water, use more bumpers than you currently have. As a matter of fact, start looking around now for extras. Throw cushions, life-jackets will work if they have too. Tie off, tie off & tie off again, but give your boat the opportunity to move; especially "up". Good luck.
