If you look at the racing side of it, sailing at this level is really cheap. As a hobby its a bit spendy but still not that bad. I have friends who carry more in fishing poles when they go fishing than what I paid for my first H16. Not to mention the price of a new bass boat.

I think laziness hits it right on the head. There is a fair amount of work to set up, launch, sail, tear down, drive home, rinse/dry clean gear and do it again for most people.
