The end of the aluminum section of the mast should probably be rounded by the manufacture to eliminate this as an issue. The Getaway has been around for along time, long enough that this type of defect would have been reported in the past if it caused problems. Maybe this is an issue with newer boats i.e. 2009+ or newer.
If it is the extrusion edge cutting into the wire...
Is your CompTip properly glued into the extrusion? If fully seated and glued, the wire should not be able to contact an "edge".
This is not a product design defect, it could be workmanship here or at the dealership who assembled the boat if it is a sharp edge being exposed.
