Sir Thomas Lipton's racing yacht 'Shamrock V' sails off from Portsmouth.
Full title reads: "Good luck go with you Shamrock V and may you bring back that 'Little Old Mug' Sir Thomas wants so much!"
The racing yacht Shamrock V is being sailed out of Portsmouth Harbour. The crew wave to people on other boats as they leave for the United States of America (USA). Shots of a passenger boat with people there to see the boat off. Various shots of Shamrock V being towed out into deeper water. The sails are hoisted and the ship moves off under wind power - a very majestic racing yacht.
N.B. The Little Old Mug of the title is the Americas Cup and Sir Thomas is Sir Thomas Lipton.
