Sailors need to know that lightning can strike out of a clear blue sky with no visual or audible warning . That’s because the warnings are too far away to be seen or heard. Trees, hills and mountainous terrain can block the sound of thunder, and cloud-cover can hide approaching storm clouds. Thunder traveling at 770 mph can be heard from only 4 miles away, while lightning traveling at 60,000 miles per second, can strike from 10 miles away. Too late to ever hear thunder. When you hear thunder, lightning has already happened, and you are within deadly range. Believing that you can count seconds between thunder is one of the most dangerous mistakes boaters make. A sailor should never take a chance, believing that what you can’t see and can’t hear, can’t hurt you. Anticipate the weather with ThunderBolt.

It makes little difference whether you’re out on salt water, or on inland water, Mother Nature can be equally treacherous for any sized sailboat. Getting caught unexpectedly by a thunderstorm out on open water is the worst of all situations facing sailors. Thunderstorm winds can capsize you, and if the storm produces lightning, bad can become deadly. Technology that can detect a thunderstorm from 75 miles away, and track it to the boat while giving him estimated time of arrival, is what every sailor has waited for.
