The giant sails get tucked away into a bag. On below video you can see how long it takes do do so .

PROUD BAGS ARE MADE FROM HUGE DISCARDED LIGHTWEIGHT
OFF-WIND SAILS THAT EASILY MEASURE UP TO HALF A TENNIS COURT

Because of the lightweight of the fabric, the sails tear easily. Often they can be repeared, and sometimes they can't. Another reason to replace them, is when the sails are not airtight anymore.

THE RED SAIL ON THIS 13 METER BOAT MEASURES SOME 130 m2.
WHEN UNREPEARABLE, THESE BIG AMOUNTS OF TECHNICAL NYLON FABRIC END AS LANDFILL

Off-wind sails, spinnaker and gennaker sails, are made in thin ribstop fabric and have a round shape, like half a ballon hanging on the front of the boats. It is the same principle as for parachutes.
