That person must provide a photo ID for the first boat, and two other individuals (16yrs+) must provide their photo ID for each of the other two boats. All three fees will be at the County resident rate so long as the first individual is paying for the three rentals. If paying cash, you must have $30 in addition to the rental fee for the $10 deposit required for each boat).
