Rob would be able to put you in touch with the mast maker.  Be aware that the centre of mass will move relative to the line of the bearings due to the mast flexing so the static condition has little relevance to the dynamic condition.  From memory they are a 33% section so a reasonable airfoil with a very high lift coefficient given their high aspect ratio.



I have some recollection of seeing the mast ends in a boat yard in Cannons Creek at the northern end of Westernport.  That is where I last saw Ozone as well.

Do you happen to know, or are able to hazard a guess as to how the center of mass is distributed on the Ozone's wing mast? Is the removed 3m still available?
