Where can I do this?
Are the costs to get started high or low?
Would I be doing this in a group, in a couple, or on my own?
Are there physical requirements that might make it difficult for me to participate?
Physical activity. Some dexterity and balance maybe required but modifications available.
So what's it all about?
Sailing is sociable, physical, and keeps you mentally alert. People who know more about it than me will tell you it doesn't have to be expensive, but there do seem to be hiring costs and memberships involved. Worth it if you can give it a try though.
