Notes:
1. Seasonal use day numbers established by alterative 2 vessel quotas.
2. Data based upon existing totals provided by the NPS for 2001 operations. Private vessel data is assumed to be one quarter the seasonal number.
3. Assumes 9 hours of operations for cruise ships (based upon 2001 average), 13 hours for tour vessels (based upon 2001 average) and 9.5 for others.
4. Average time in mode values are based upon vessel observations from NPS staff and vessel operators.
