When the wind picks up, you have to reduce sail. You may have noticed in the videos, the many little "strings" hanging from the sail in horizontal rows. These are "Reef Points". To take a reef, the sail area is shortened by rolling/tucking the sail up and tying it up in rolls with those strings..Reef Points.
At the same time, the yard is lowered to get the sail area down closer to the deck....
Less healing moment..And
OFF we go....Arguably, This is the fastest point of sailing...
Reefed Down... and
Close Hauled with a
Good Breeze..
NB
