Another important aspect of navigation safety should adjust the amount, which is adapted to drive the wind conditions. As wind speed increases the crew should gradually reduce the amount of swimming.
A small boat only jib and mainsail, a jib and a partial reduction by rolling up the mainsail, a process that is called to the selected part of the reefing main »: Scooter boom is changing the face of a boat, without him, to reduce more a little ride.

But the sail to the mast or boom slot is suspended, if not properly function. Mainsail furling is almost never used while racing because it results in a less effective method to maintain the profile of the most popular classical plate roller reefing.

However, since increasing the size of the boat, enjoy the dramatic roller furling.
