We just received this in an email from our insurance company. It does seem like good idea.
Hurricane Preparation:
If a Hurricane Watch or Warning is issued for your area by the
National Oceanic & Atmospheric Administration (NOAA), we will pay
50% of the cost up to a maximum of $1,000 for having your boat
moved by a professional, or for a professional haulout, or for the
professional execution of a hurricane plan. In addition to professional
moving or a professional haulout, covered expenses include, but
are not limited to, haulout, blocking, lashing to in-ground anchors,
powerwashing and relaunch.
