are 9 and 12 and ever since they were little have practically lived in rock climbing harnesses hooked with carabineers to the end of the halyards, swinging from headsail to mast
, around shrouds etc. Keeps them out of the cockpit
during cocktail hour and never have to worry about them falling overboard! Also a great way to help you meet other kid-boats...it's an instant kid-magnet. We also just tried attaching a wind
scoop above the climbing harness as sort of a mini-spinnaker.
