Sailing is relaxing, or it may be exciting if you are racing. Sailing is quiet. Of course if the wind is strong and the waves are high it may be noisy. You can find solitude and commune with nature. On the other hand you can take friends along and share the experience.
Sailing is environmentally friendly.
There is no need to feel guilty or apologetic about what you are doing. All of the above are true. And each person will make his or her own additions to the list. But the bottom line is that sailing is fun. There is something for every personality.
