When in a boat what is the best course of action if you see a thunderstorm approaching?

Answer 1

I have been through many thunderstorms while sailing. Unless you are in a very small boat, that could be upset by larger waves, it is no different than sailing at any other time. As long as the wind and waves are not extremely drastic, it's a matter of wearing foul weather gear and staying warm while making sure your sails are trimmed for the likely stronger winds. Storm sails or at least reefing the main sail and hoisting a small jib would be recommended. I highly recommend that all larger ocean going sailboats have a grounding system. This system basically makes sure any electricity from lightning would travel down the (usually aluminum) mast and into the keel bolts or other metal directly to the water. As long as the electricity goes directly into the water, it shouldn't harm the boat in any substantial way. I have never had any real problems in thunderstorms. Heavy winds and waves are the worst threat and then only if you are unprepared or so close to land that it threatens to push you ashore.

Answer 2

Get to land quickly as soon as possible due to the fact that you are in the middle of an open area as soon as you hit land stay low to the ground if you are in open water you are the closest thing for lightning to ground itself to.

Answer 3

If the boat is large enough to have a cabin, go inside. Don't touch anything made of metal, and stay away from the cabin walls.

Otherwise, crouch down in the center of the boat, away from oar hooks or anything else metallic. If you have a tarp or raincoat, cover yourself; don't use an umbrella, as it's basically a lightning rod.

Should the boat start to flood, bail water as necessary. Otherwise, ride the storm out and repair any damage after it has safely passed.

Answer 4

As long as you are inside there is no danger of a person being hit by lightning. However the boat itself still stands a chance of being hit causing a fire. If at all possible you should dock and find shelter. Boats and lightning don't mix.

Answer 5

Try and get off of the water as fast as possible; water attracts lightning. And you probably shouldn't have gone on the water while there were chances of thunderstorms. =D
