Crew Rating

Crew effect over their career: 43.42 percentile among crews with 30+ races (± 0.118 rating points on a spread of about 0.04 between crews; 13 races with rated skippers). Limited evidence: with this few races the estimate stays close to the middle of the pack.

How much better or worse boats do with this sailor crewing than their skipper's rating predicts. The rating is on the skipper scale: the team's skipper average plus the crew's difference from their teammates, multiplied by 18.7 so a team's crews spread out like its skippers. Crews on one team differ far less than skippers do, so the ± is as large as the spread itself: use it to line crews up across teams, not as a ranking within a team. Percentile is among all rostered crews in that league and season.
