The commissioners shall preserve in a well-bound book a record of their acts and of the rules and regulations adopted by them for the direction and government of pilots. They shall also preserve upon record a list of all persons appointed pilots by them, and of those whom they may declare to have forfeited their licenses. All persons interested shall have access to and be permitted to take copies of the record, and copies from such records, certified by the chairman, are presumptive evidence of the facts stated therein.
