Only got into sailing in my mid 40s after years of pestering by the sailors that my local club where I windsurfed. Biggest regret of my life not getting into it sooner. I am totally addicted.
Been at it a few years now and do the open race circuit and the nationals. Reminds me so much of MTB racing in the good old days 80/90s; Great crowd.. familiar faces.. fantastic crack.. get to spend weekends at some stunning locations.
Depending on the boat.. it can be a very cheap sport. It’s much cheaper than my MTB was and none of the new model cr*p every year.
Benefits.. no broken bones.. 15mph feels like 50.. worst that can happen is you can get wet (albeit the exception of course).
There are some real crap boats out there though and unfortunately lots of clubs are populated by very old guys offering to take you out in boats that will immediately put you off sailing. Choose the boat and the instructor wisely and you’ll have a pastime that can carry you competitively to an age no other sport can.
