NATIONAL RECREATIONAL BOATING SURVEY Understanding Its Structure and Impact Tamara L. Terry, ERAC Committee Chair (on behalf of 2014 ERAC C1 charge team) October 19, 2014 NASBLA 55 th Annual Conference Bar Harbor, Maine

Why does it matter? Results from the NRBS will probably be used by the Coast Guard as one tool to measure your states, programs, and campaigns in the future. Data from the NRBS will definitely be used to measure the success of actions in support of the National Recreational Boating Safety Program Strategic Plan. 2 National Recreational Boating Survey: Understanding Its Structure and Impact

Why does it matter? By understanding how the survey is conducted and how the data is collected, you’re better equipped to understand the findings -Allows you to provide input on results; explain anomalies -Allows you the opportunity to offer suggestions to improve future versions of the survey 3 National Recreational Boating Survey: Understanding Its Structure and Impact

What’s in it for me? Establishing baseline numbers of vessels in your state -Registered vs Unregistered -By Boat Types -Has a number of caveats that will be discussed today Determining opinions and perceptions about boating -May supplement or validate existing data -May provide data that cannot be obtained through other sources 4 National Recreational Boating Survey: Understanding Its Structure and Impact

How can we help? 6 National Recreational Boating Survey: Understanding Its Structure and Impact

July/August 2014 Small Craft Advisory articles -Focused on explaining exposure hours and “risk ratios” -Responded to questions the team—and many of you—had asked One additional item not covered there: Why is there no lifejacket wear question on the survey? -Will provide similar resources in the future as opportunities arise How can we help? 7 National Recreational Boating Survey: Understanding Its Structure and Impact

The NASBLA Lighthouse Online Forum -Warehouse of additional survey references and resources -A place to ask questions and post comments How can we help? 8 National Recreational Boating Survey: Understanding Its Structure and Impact

Expanded Data Pulls -In cooperation with the USCG, the team is currently exploring the more detailed data available from the NRBS -Items that were not presented in the 2012 NRBS Summary published by the Coast Guard, but may be of interest to you -First on the list: Providing states with the NRBS estimates of 1) the number of registered/unregistered boats by boat type within each state, and 2) the exposure hours for these groupings. How can we help? 9 National Recreational Boating Survey: Understanding Its Structure and Impact

After first review by the team, it appears that some results estimated from the NRBS at the state level are relatively dependable for states’ use -Overall (total) number of registered and unregistered vessels (all boat types combined) -Number of powerboats (registered and unregistered) -Exposure hours calculated for these two groups using these boat numbers NRBS boat numbers Lessons learned 10 National Recreational Boating Survey: Understanding Its Structure and Impact

What makes these results more dependable/accurate/ precise? -Powerboats dominate the data sets -Powerboats are registered in all states NRBS boat numbers Lessons learned 11 National Recreational Boating Survey: Understanding Its Structure and Impact

Other results aren’t quite as dependable/accurate/ precise -Non-powerboat groups -- both the number of vessels and presumably the exposure hours calculated from these numbers NRBS boat numbers Lessons learned 12 National Recreational Boating Survey: Understanding Its Structure and Impact

What makes them less dependable/accurate/precise? -These groups make up a smaller proportion of the total number of vessels in all states -Significant differences in the way that non-powered vessels are registered and/or titled from state to state -Some groups’ sample sizes are not large enough to generate statistically valid exposure hours -In the case of the canoes/kayaks groups, the NRBS figures include motorized as well as manual vessels NRBS boat numbers Lessons learned 13 National Recreational Boating Survey: Understanding Its Structure and Impact

Don’t take our word for it… -You can see the data tables for yourself – and we encourage you to do so…especially for your state -Visit The NASBLA Lighthouse at Click on “Get Equipped” and choose “National Recreational Boating Survey” -Let us know if you see anything else of interest in your review NRBS boat numbers Check them out yourself 14 National Recreational Boating Survey: Understanding Its Structure and Impact

Next on ERAC’s list of NRBS items to explore -COMING SOON (to be released shortly after the conference): Simplified explanation/chart of weighting process used in the Participation Survey portion of the 2012 NRBS -Examination/comparison of NRBS exposure hours by boat type in relation to accidents involving those boat types (contingent on some of the validity issues we’ve discussed here today) -Consideration of potential impacts/differences in NRBS trip survey respondents from multiple vessel versus single vessel households What else can we help you with? 15 National Recreational Boating Survey: Understanding Its Structure and Impact

Next on ERAC’s list of NRBS items to explore -Consideration of NRBS data collected with regard to the boating day (day of week) that was sampled -Exploration of the pros/cons of using exposure hours versus registered boats as the denominator in risk equations -Exploration of the pros/cons of using fatal incidents versus fatalities as the numerator in risk equations What else can we help you with? 16 National Recreational Boating Survey: Understanding Its Structure and Impact

Next on ERAC’s list of NRBS items to explore -Consideration of methods that could be used to estimate registered boats/exposure hours in non-survey years (for trend analysis) -Consideration of methods to account for survey non-response bias -Consideration of methods to address ongoing issues regarding the calculation of casualty and fatality rates—especially for states where a large proportion of fatalities or injuries involve out-of-state boaters What else can we help you with? 17 National Recreational Boating Survey: Understanding Its Structure and Impact

We want to hear from you… -Have the ERAC products produced to date been useful to you? -Are the upcoming ERAC work items we shared today of interest? -What other items would you like ERAC to explore with regard to the NRBS? -If you don’t have a solid handle on what you want, just give us the general gist of it us at subject: We’d appreciate input 18 National Recreational Boating Survey: Understanding Its Structure and Impact
