Divisions
Races classify into divisions: Men’s (M), Women’s (W), heavyweight (HWT) or open, lightweight (LWT), etc. The divisions divide into 8+’s, 4+’s, and so on. For a typical regatta, you might see separate races scheduled for M8+, W8+, W4+ down to W1x and M1x. There may be separate heavyweight and lightweight divisions. Lightweights may require a weigh-in before the start of the regatta.
