I have an old Hobie 14T (approx 20yr) I am in Australia. My sidebar is
cracked almost right through at the chainplate and needs replacement. II
have priced a new one and it costs half of what I paid for the boat (and is
black - whereas mine are silver [aluminium]) so I am considering sourcing
some aluminium section to make a replacement. Could some mast section be
used as a replacement if I can find some?

Cheers
