the hull # is foun din the HIN (similar to VIN, but for boats). It is etched or imprinted in the hull, usually at the starboard quarter or stern. Currently the hull number for your boat is generally found in the 6th, 7th, and 8th digits of your HIN (there was a different protocol previously, I forget the exact year of the change but I think it was early 80s).
E.g. With HIN "CYA42273D889" the hull # would be "273".
