What this video covers

A 14-metre sailboat faces a calculated lightning strike probability of 0.125% during a 30-minute exposure to a low-intensity storm and 0.626% during a moderate-intensity storm.13:27 These calculations assume the vessel occupies the most active zone of a storm, using a Poisson distribution to model the frequency of independent lightning strikes.10:28 The effective strike area for a sailboat is defined by a circle with a radius equal to the mast height, here estimated at 20 metres, as the mast acts as a lightning rod.6:34 In high-intensity storms, the probability of a strike increases to approximately 1.2%.14:05 Beyond the risk of direct hits, secondary discharges pose significant threats to crew safety and onboard electronics.14:43 Proper grounding systems are essential to mitigate risks of hull breaches, fires, and equipment failure.14:58 Sailors should maintain distance from metallic components and rigging during electrical storms to avoid secondary strikes.14:10
