Since you can't easily measure current without being 'inline' with the circuit (hard to do with most multi-meters since they typically won't pass a very usable level of amperage), I would recommend testing the voltage on the battery when it is disconnected, then measure again when connected to the boat, if the voltage drops a few decimals then there is current draw.
They do make inductive type ammeter that allow clamping over a wire, this could be helpful if the current draw is enough to register, here are a couple for cheap:
