Swinging from the mast

A quick post - This last summer we bought Kyle a full harness so he could swing from the halyards. I had read about the kids on a boat named Kamaya having fun swinging from a rope attached to the mast of their boat and thought we should give it a try. Up until recently Kyle didn't seem very interested in the whole idea and had a healthy fear of going up the mast. But two days ago he decided he'd try it and now he's hooked. He wants his homeschooling to include three sessions of PE per day with swinging as the main attraction.  

Note - Luckily he doesn't want to go all the way to the top of the mast.
