Do the various size G-cats use the same mast extrusion? I need to source a replacement mast butt (bottom end extrusion) for a G-cat 5.7 and learn how these are rigged for raising the mast. Any help is appreciated as it is for the boat that we refurbished for a wedding gift and its new(lywed) owners.
