I don't believe that it is standard practise to repair masts on larger boats, with the exception of jury-rigging boats that have been damaged at sea in order to allow them to make landfall.
Perhaps I should rephrase that - I don't think it is safe to sail a boat with a repaired mast for any length of time, and I have never encountered anyone who felt differently and sailed their boat with a jury rig.
I think it is less of an issue in the case of a dinghy, as the boat is used for inshore daysailing and rescue is almost a certainty in the case of mishap.
I think that your friend may find the cost of a new mast to be not much more than the cost of repairing the broken one, and the new one would be a whole lot safer...
