Teaching the children to .... Sail

When our kids were growing up they learned to shoot bow and arrow or play t ball or soccer.  We saw these small boat/tubs bobbing around in the bay and later saw the class.  They were learning to sail.  I would guess they were 8-10 year olds.  They would lash all the boats together and haul them out into the bay behind a zodiac and practice.  This was some of their "on land" learning.  Can you imagine how good they will be by adult hood?
