It's a contribution of essays by various writers and each addresses the topic from their own angle. One starting point is to observe that not all sailors are the same, and by classification you can learn about differences and commonalities, both avenues for investigation.
Two dimensions were highlighted, what I call motivation and character.
1. Social sailors: those whose primary interest is taking friends and family out on the water; often found in sailing club bars
2. Competitive sailors: those whose primary interesting is optimisation, gaining the most from sail, hull, wind and tactics
3. Sailing to sail: those who sail to be out on the ocean in the company only of waves, testing their metal against the elements
- a. Rookie: we all are one at first, literally learning to ropes
b. Team mate: one of the crew, doing their job reliably without drama, mucking in when required
c. Superman: able to winch on further when all others have leant back, feeling there is "enough" tension on the line
d. Yogi: tends to wear shorts and sandals in winter as it helps them feel the wind shifts better
e. Minister: reassures crew when the level of heel gets alarming, bringing refreshing hot drinks to the cold helm
f. Salt: impassive, aware of all the sails and their trim, able to tweak any line to lie a little better
g. Skipper: controlling, demanding, in charge, responsible
h. Student: forever learning, experimenting and discovering
I'm sure the same general principles apply for kayakers and rowers, so this could be a what type of boater are you.
