We had a microburst here Labor Day weekend.
One boat sunk, 5 others that were on mooring
balls broke free and were beached. One on a mooring
ball had chained his boat to the ball. The winds drug the boat and ball with concrete anchor
attached up on the beach.
Since there was no way to get equipment
near where the boats were beached, all had to be dragged back into the water.
Boats in the slips did better, but not much. Several broke dock
lines, on hit the head
of the slip so hard it broke the concrete, he also lost
mounted A/C over the side and most of his rub rail as well.
