Alcohol caused more deaths. Operator inattention caused more accidents (Pg 7). [Alcohol use certainly did cause "more" deaths. Look at the chart on page 23. It's 3 times the factor of any other known cause.]
This report shows the number of deaths, of all boat sizes, actually goes down with more people on board. [Obviously this finding has it's limits. Is one person in a 12 foot open skiff more dangerous than 12 people in the same boat. There has to be an optimum number. It may not be one - depending on the size of the boat, but it isn't just "more." One may well be more dangerous than two or three in a given boat, but are three drinking people safer than on sober one? Solo is more dangerous, but can be compensated for in ways that drinking cannot. Hence, the purpose of this thread.]
Credible reports from credible agencies probably yield more significant knowledge compared to talking to any one individual. [Agree. However, if the "any one" you are talking to has read and understands the "credible reports" and also has first hand knowledge and insight, or if the person has experience in a particular activity subsumed in a report's mass of data and generalizations, then you certainly can benefit from talking to the guy.]
Aye.
