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.
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.
| # | Crew | Rating | Range The dot is the rating. The shaded band is where it plausibly sits (90% range): a wide band means little evidence, and bands that overlap mean the crews cannot be told apart. The dashed line is the team's skipper average. Ratings are on the skipper scale and crews on one team differ far less than skippers do, so use them to compare crews across teams, not to rank within a team. How crew ratings work → |

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.
