Have come in from w/surfing during an electrical storm...scary. Years ago a mate & I were fishing in my boat on a calm/overcast day. We could hear this loud buzzing sound, looked everywhere & it turned out that it was our fishing rods/lines. At one stage I looked over at my mate & his hair was standing straight up, so we decided to drop the aerial & rods down, sat on the floor & waited for a while until it passed.
Hope you had a dunny bucket handy.
