Boating is one industry I believe is in secular decline when looking at sales figures over the years. The peak of the boating market came in the mid-1970’s and has been trending downwards ever since. Over half a million boats were sold per year in the early-to-mid 70’s. Within the past ten years, that number has fallen to under 180,000, or approximately just one-third of its absolute market peak. Arguably, in terms of leisure and vacationing pastimes, boating has decreased in popularity due to other available recreations.For anyone looking to explore the trend further, below are a list of publicly trading boat manufacturers and retailers:Brunsick Corporation (BC)CompX International (CIX)Johnson Outdoors (JOUT)Malibu Boats (MBUU)Marine Products (MPX)MarineMax (HZO)MCBC Holdings (MCFT)Ocean Bio-Chem (OCBI)West Marine (WMAR)
