Seaworthy Magazine: Thunderstorms - A Few Members' Accounts
Reading your current issue of Seaworthy, I was drawn to your "Small Stuff' article on thunderstorm experiences. After 40 years of cruising, I would like to give you my procedure when I encounter a "severe one":
Head for open water. Pick a spot on the horizon that has no obstructions and then note the compass course as well as the reciprocal course. Calculate the time running on the first course and then turn on the reciprocal course for the same period of time. (Wind must be taken into account.) Keep going over the course until the storm passes.
