  We present results from model tests to investigate the effect of drafting in
swimming, in particular for the lead swimmer. The drag for scaled-model passive
swimmers was determined accurately at Froude numbers comparable to conditions
for actual human swimmers. Several positions of a draft swimmer at different
separations behind and alongside the lead swimmer were investigated. It was
found that a lead swimmer can experience an advantage from a draft swimmer.
Several other positions of the draft swimmer relative to the frontal wave
generated by the lead swimmer were also considered. These results indicate
favourable and undesirable positions during passing.
