I'll never forget back in the early 70's I was with my dad and we were heading west down LIS, in a 28 ft. sailboat, around the Clinton area. It was pretty dense fog and light winds. He was teaching me about using the horn, using your EARS and dead reckoning/basic course plotting. Out of the grey I begin to hear the drone of a motor and mention it to my dad who tells me it is a power boat moving fast. Well out of the fog this power boat comes blasting along (viz was about 300 ft) they see us, knock it back and idle over. Holding a PLACEMAT CHART in his hand this yahoo says "Hey ! Which way to Block island ?" My dad says
" That way (pointing Se)" and before he can finish the guys yells thanks and blasts off into oblivion. I mean Block was like 50 miles away from where we were.
The placemat chart. To this day all the two of us can do is shake our heads in disbelief.
