30 Part II: Characteristics of the U.S. Ferry System States. Thus, these data underestimate the actual number of international routes that have ter- 2001 minals in the United States. The passenger capacity of most vessels in the National Ferry Data- 501 to (14) 2000 NULL base is greater than 12. Thus, it is likely that most of the vessels that operate on international (81) routes in Table 1 must meet 33 CFR 104 requirements. (138) 151 to (64) 1 to 49 500 (162) (226) 2.2 Passenger Capacity and Location of Relatively 50 to 150 High-Risk Targets Note: Numbers in parentheses The passenger capacity of the USFS, according to the National Ferry Database, is shown in Fig- indicate the total number of ure 1. At least 40% of the national fleet has a passenger capacity that is less than or equal to 150 vessels in each category. and, thus, do not need to meet the requirements of 33 CFR 104 (i.e., they do not need to develop Figure 1. Passenger a U.S. Coast Guardapproved vessel security plan). Roughly 10% of the entire fleet has a pas- capacity in the U.S. senger capacity of less than 50, meeting some definitions of water taxis. The "NULL" group in ferry fleet. Figure 1, which did not provide their passenger capacity, represents 20% of the national fleet. This group consists of relatively small operators and, thus, is more likely to have vessels that fall in the categories that have passenger capacities of less than 150. Thus, overall, the percentage of the national ferry fleet that does not need to meet 33 CFR 104 requirements based on passenger capacity is estimated to be roughly 60%. During the time of the National Ferry Survey, nearly 40%, or 257 vessels, met the criteria for 33 CFR 104. While this number of vessels was likely reasonably accurate in the year 2000, it has increased in the 5 years since survey completion. If more stringent security regulations are adopted for vessels with a passenger capacity of 500 to 1,999 and for vessels with a passenger capacity of 2,000 or more, this would affect 81 and 14 vessels, respectively, based on the fleet rep- resented in the National Ferry Survey completed in the year 2000. As may be expected, all 14 of the ferry vessels in the National Ferry Database with passenger capacities of 2,000 or more are located in the two states with the highest ridership, Washington and New York. Two vessels with a capacity of 6,000 are located in New York, in addition to three vessels with passenger capacities of 3,500. In the state of Washington, there are seven vessels with passenger capacities of 2,500 and two vessels with passenger capacities of 2,000. Thus, in the year 2000, five vessels in New York and seven vessels in the state of Washington fell within the highest relative risk category based on N-RAT. Table 2 shows the number of ferry vessels in the two highest passenger capacity categories (i.e., synonymous with relative high risk) by state. The number of vessels in the highest-risk categories is greatest in the state of Washington, although ridership and, presumably, the number of ferries with passenger capacities of less than NULL (42) 500 are greater in New York. More than 100 GT (149) Less than (486) 100 GT 2.3 Vessel Gross Tons Based on data in the National Ferry Database, 22% of vessels, or 149 vessels, in the year 2000 Note: Numbers in parentheses exceeded the 100 gross ton regulation tonnage. There was a 6% non-response (i.e., NULL) in this indicate the total number of category. It is likely that all the vessels in the NULL category are less than 100 gross tons. Thus, vessels in each category. about one-fifth of the USFS must meet 33 CFR 104 requirements based upon tonnage alone. (See Figure 2. Regulation Figure 2.) gross tonnage of the U.S. ferry fleet. Of the 149 vessels with more than 100 gross tons, 13 listed a passenger capacity that is less than 150, and 12 did not report their passenger capacity. Thus, somewhere between 13 and 25 (9% and
