This sounds like a reasonable number of active participants in North America. I suppose we can bump it up for non-English speaking countries and for English countries that have their own magazines (hence low penetration by Sea Kayaker). It would be interesting to compare this to sales of, say, composite sea kayaks and high-end plastic SKs. > Again this formula > is not perfect.

This reminds me of cross country skiing in its heyday in the '70s. It was estimated that one out of 5 Canadians were XC skiers. But most of them had skis but didn't know how to ski etc. The skis were kept at the cottage. The comparison was to swimmers, where 40% of Canadians (or some other huge number) were claimed to be swimmers. This meant counting every person who donned a bathing suit and entered water. In fact, swimmers who train or do it for exercise on a regular basis are relatively few. Hence: > The 24.8 million figure for paddlers is a pipe dream. Unless we include every person who ever sat in a paddle boat. This is useful info, Ralph. Thanks! Mike PS - my motivation is estimating sales potential for a widget that might reasonably only interest a "serious" paddler. Nothing real yet, just floating ideas. *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
