The white male Baby Boomer has been the core of the boating industry for decades, buying millions of boats, engines and accessories. Each year, the age of the average boat buyer is about six months older than the year before, according to analysis by Info-Link. Info-Link has tracked buyer registration data back to 1997 and in that time, the average buyer age has increased by about 8 years. Although the periods donât line up perfectly, thatâs much faster than the aging of general population from the 2000 to 2010 Census, where the average age increased only 1.9 years to 37.2 years old.

Mortgage and credit card costs impact younger, lower-income consumers more than older, higher-income ones.
