I said essentially the same thing as a comment on the page the article appears on. It is the total number of hours spent in the "Zone" by the different types of kayaks divided by the number of attacks on each. That will give you the attacks per, probably, hundreds of thousands of hours in the "Zone".

Sample size is not a term that applies here. What you have is a small number of occurrences. Sample size is the number of data points that you survey in order to make a prediction about a population. Like the number of Hobie owners you question in order to find out if they have been attacked by a shark.
