As an ex ARETHUSA lad, I am intrigued by the deeds of daring-do. I have the main mast as 52 mtr deck to truck. As a petrified youth I made it up the fore mast to touch the button at the mast head. Now visiting my wife in a nursing home in Edmonton, they have a 15 floor building adjacent that must be almost the height, approx. 150 ft. ? It makes my blood run cold to think of scaling that height some 50 odd years ago. Quite apart from the "button boy" on the top with nothing to hold on to. Other thoughts? Peter
