What is the minimum coxswain weight?

The minimum weight for a coxswain, wearing racing uniform, is 55.0 kg for all coxswains (Rule 29.4). The weighing scales indicate the weight to 0.1 kg.

The same minimum applies to coxswains in lightweight races (Rule 29.6). A coxswain below 55.0 kg may make up the weight with deadweight in a sealed bag carried in the boat close to them (Rule 29.5).
