I wouldn’t say an ST40 sheet winch is undersize for a 37. Pawl failure can happen at any time on any winch and is normally down to lack of regular cleaning and maintenance.
They should be fully serviced once if not twice a year and the pawls and springs lightly oiled monthly to keep a winch in good order.
It is rare for more than one pawl to fail at the same time so regular servicing will normally pick up any single failures that can easily be replaced.
