It's That Time OF Year... Hurricane season

What can you do to increase the odds of your boat surviving a hurricane? Quite a bit, actually.

After every hurricane, starting with Alicia in 1983, Boat Owners Association of the United States (BoatU.S.) has been evaluating what worked and what didn’t and sharing those lessons with boaters. The BoatU.S. Insurance claim files show that in most cases, boats are safer out of the water in hurricane conditions. When a hurricane watch is issued, BoatU.S. recommends that, if at all possible, you load your boat on its trailer and move it inland or have your boat hauled out. Whatever your current plan, there are five steps you should take before the next hurricane warning to give your boat the best chance of making it through the storm and to protect yourself if it doesn’t.

1- Find a safe place to store your boat when a hurricane threatens.
Hurricanes pack wind speeds of 70 to 130 mph; winds in excess of 200 mph have been recorded. But strong winds are not the only risk to think about when storing your boat in a tropical storm. Hurricanes can create destructive waves when blowing over open water for less than a quarter-mile.

Six to 12 inches of rainfall in 24 hours is normal, and 24 inches in 24 hours have been recorded. You should consider looking for another place to keep your boat in a tropical storm if your current location does not have any natural protection from the wind, is exposed to open water in any direction, or could be prone to flooding.

But, as Superstorm Sandy so clearly demonstrated, the biggest danger comes from storm surge, extreme high water levels that can be 10 feet or more above the highest high tide. NOAA’s Sea, Lake, and Overland Surges from Hurricanes (SLOSH) model lets you look at the highest water level recorded in your area from storm surges in past storms (see online resources on back). You can use the maximum surge height to evaluate how secure your boat would be in a hurricane. If your boat’s on a floating dock, are the pilings high enough? Or would the surge float the docks off the pilings? If the marina or boat club is protected by a seawall, would water come over it? How high would the water be in the hardstand area? High enough to lift your boat off its jackstands? Would there be waves where boats are stored ashore? If you’re not happy with the answers, try to find another place to keep your boat during a storm.

2- Determine where to get the most accurate forecasts for wind and surge.
Once a storm is approaching, your exact preparations will depend upon the forecast for wind and surge in your area. The National Hurricane Center provides the most complete and current information on potential wind speeds and probable tracks. The National Weather Service’s Probabilistic Hurricane Inundation Surge Height (PHISH) model (see online resources) forecasts surge heights when a hurricane is threatening an area.

3- If you keep your boat in a marina, get a copy of your marina’s hurricane plan and review it carefully.
You need to understand your obligations, and theirs. To see some sample hurricane plans from marinas around the country, visit the BoatU.S. Hurricane Center.

4- Create your own hurricane plan
Stripping off sails and canvas, doubling lines on boats left in the water, lengthening scope on moorings, and tying the boat down if it’s on land can make the difference between a boat surviving a storm and not. The BoatU.S. Hurricane Center details hard-won lessons learned on how to secure your boat including a downloadable hurricane preparation worksheet. Use that to think through what you will need to do when a watch is issued.

5- Check your insurance policy for hurricane haulout, salvage, wreck removal, and fuel-spill coverages.
Read the fine print in your insurance policy to make sure you’re covered before and after the storm. Some insurers will pay part of the cost of having a professional move or prepare your boat once a hurricane watch is issued. The best policies cover the cost of salvage without deducting it from the payment to you for damages to the boat. They also provide additional coverage for wreck removal and fuel spills under the policy’s liability provisions.
