emerges. When NSRE estimates <strong>of</strong> the number <strong>of</strong> participants<br />

in each type <strong>of</strong> activity are used to calculate exposure measures,<br />

kayakers appear to be much more at risk than canoeists. NSRE<br />

2002 estimates showed that kayakers suffered 3. fatalities per<br />

million participants while the fatality rate among canoeists was<br />

almost half that, at 1.9 per million participants.<br />

<strong>Accident</strong> and injury data for canoeists and kayakers also<br />

illustrate the need for different risk mitigation actions. Data<br />

from the Coast Guard observational study found that, in general,<br />

more than 84 percent <strong>of</strong> kayakers wore PFDs, in contrast to only<br />

27 percent <strong>of</strong> canoeists. These data imply that a requirement to<br />

wear PFDs would affect kayakers less than canoeists. In addition,<br />

the high rate <strong>of</strong> PFD wear among kayakers indicates that factors<br />

other than PFD use affect the outcome in such accidents.<br />

However, Coast Guard data also show that 48 percent <strong>of</strong> the<br />

kayakers who were fatally injured from 1996–2002 were not<br />

wearing PFDs, 1 indicating that the kayakers observed during<br />

the Coast Guard study may not have been representative <strong>of</strong><br />

the kayakers involved in fatal accidents. Such discrepancies<br />

suggest that surveys and observational studies must be carefully<br />

designed to ensure that the data collected are representative <strong>of</strong><br />

the participants most at risk. Such discrepancies also illustrate<br />

the potential to underestimate actual risk, which complicates<br />

any attempt to evaluate intervention strategies.<br />

The ability to assess risks to recreational boaters and<br />

determine the effectiveness <strong>of</strong> actions taken to reduce<br />

recreational boating accidents and fatalities requires accurate<br />

data. Without an effective data collection method, the Coast<br />

Guard’s boating safety program cannot adequately determine<br />

the risks in boating nor effectively reduce the number <strong>of</strong><br />

accidents, fatalities, injuries, property damage, and healthcare<br />

costs associated with boating accidents. Although some<br />

measures <strong>of</strong> participation, activity, and exposure are available<br />

for recreational boating, using those measures to make<br />

risk-based decisions can be difficult. For example, the Coast<br />

Guard calculates accident and fatality rates based on the<br />

number <strong>of</strong> registered boats. Unfortunately, boat registration<br />

requirements differ considerably among States. Some, like Ohio<br />

and South Carolina, require registration <strong>of</strong> all watercraft; others,<br />

like Vermont and Maryland, limit registration to motorboats<br />

only. Further, the Coast Guard’s system for documenting and<br />

numbering boats is not comprehensive and does not necessarily<br />

correspond to State registration requirements. Consequently,<br />

accident or injury rates based on boat registration data may<br />

not adequately represent the size, composition, and use <strong>of</strong> the<br />

recreational boating fleet for risk assessment purposes.<br />

PERSONAL FLOTATION DEVICES IN RECREATIONAL BOATING<br />

THE SAFETY BOARD TAKES ACTION<br />

The insights provided by the forum prompted the Safety Board<br />

to take action by issuing four safety recommendations in the<br />

following areas: implementing a more effective risk assessment<br />

program for recreational boating; collecting data on boaters,<br />

boats, and boating activities; improving boater education; and<br />

increasing industry efforts to promote PFD use.<br />

The first recommendation focused on the Coast Guard’s<br />

recreational boating risk assessment program. The Safety Board<br />

was concerned that the Coast Guard’s risk-based approach to<br />

recreational boating was not consistent with standard practice in<br />

system safety, 2 and concluded that an effective risk assessment<br />

program with new survey and research methods, at both the<br />

national and State levels, was required to collect, analyze,<br />

and disseminate data and information on recreational boating<br />

participation and activity. Such survey and research methods,<br />

stated the Board, can also provide the basis for longitudinal<br />

studies <strong>of</strong> educational and licensing programs, identification<br />

<strong>of</strong> best practices at the State level, and ongoing observational<br />

studies <strong>of</strong> recreational boating activity and boater behavior. As<br />

a result, the Board recommended that the Coast Guard develop<br />

measures <strong>of</strong> recreational boating activities, boaters, and boats<br />

that can be used to identify and evaluate the risks in recreational<br />

boating. Once those measures have been developed, the Coast<br />

Guard should collect the appropriate data at the Federal and<br />

State levels and use it to evaluate the effectiveness <strong>of</strong> recreational<br />

boating safety programs. Furthermore, the data and the results<br />

<strong>of</strong> the evaluations should be provided to States for use in their<br />

own boating safety programs.<br />

The second recommendation to the Coast Guard specifically<br />

emphasized the need to collect boater education data. In that<br />

recommendation, the Safety Board urged the Coast Guard to<br />

ensure that the measures <strong>of</strong> recreational boater characteristics<br />

include documentation <strong>of</strong> boater educational experience<br />

that can be used at both the Federal and State levels to plan,<br />

coordinate, and evaluate recreational boating education and<br />

licensing programs.<br />

The Safety Board addressed the concerns about boater<br />

education in a recommendation to NASBLA. Citing<br />

deficiencies in the National Boating Education Standards, the<br />

Board recommended that NASBLA modify its standards to<br />

ensure that boating safety education courses adequately discuss<br />

high-risk boating populations, boats, and boating activities, and<br />

present sufficient detail about the range <strong>of</strong> PFD technologies<br />

available.<br />
