Achieving a new milestone, Lynne became the first person to swim across the Strait of Magellan. She swam in 42-degree F (5.5 degrees C) water, through a storm with a 9-knot cross current, in 1 hour 2 minutes.
Lynne was the first woman to swim across Cook Strait between the North and South Islands of New Zealand. After being pushed back by currents for 5 hours, she completed a 20 mile crossing in 12 hours and 2 ½ minutes. This swim was heralded by New Zealand’s Prime Minister Rowling as having helped heal relations between his country and the United States.
Lynne was invited to compete in an international swimming race in the Nile River by the Egyptian government. The water was extremely polluted and during her training in the river Lynne became very sick. She competed in the race anyway and she passed out and was pulled from the water.
Shortly after her 1972 swim, Lynne’s record was broken by Davis Hart. Rising to the challenge, she returned to England and regained the men’s and women’s records for swimming from England to France, with a time of 9 hours and 36 minutes.
