Skippers with at least 4 rated boat-races this season, ranked by their rating after their last race of the season. Percentiles count ties as half.

Skipper ratings over their careers
Week at Nichols SchoolWeek before / elsewhereLine colour = skipper (’yy = graduating class)

Weekly rating of every skipper on the roster across their whole career so far, one point per week their rating moved. By class year lines every graduating class up at the start of its freshman year, so each class sits one year further left than the one after it. Hover a line to isolate it.

What is pushing these ratings up or down

Crews are only compared through the skippers they have shared. A skipper's boats do a little better or worse than their rating predicts depending on who is crewing, and the rating is built from those differences. Each big blue dot is a crew on this roster, each small square a skipper they have sailed with, and each line a pairing: blue pushes the crew up, orange pushes them down, thicker means more racing behind it. Click a crew or a skipper.

Ranked crews have at least 8 races this season; * means low evidence (under 8 races this season, or under 30 career races with rated skippers). Ratings are on the skipper scale (×18.7 the crew effect). League percentile also reflects how strong the team's skippers are.
