As shown in the illustration,
use A parts (standard parts)
for parts 44 - 46 when the bow
will face to the right and B parts
(optional parts) when the bow will face to the left.
Parts
-
Fold once and glue the folds together,
then give the sails a bulging appearance.
If you plan to have the bow face to the right,
curl the sails so that surface A will bulge out.
If the bow will face to the left, curl the sails
so that surface B will bulge out.
For parts 62 - 64, choose A parts
(standard parts) or B parts (optional parts)
depending on the direction in which
the bow will point.

Parts -
Attach parts 65 - 70 (the yards) to the vessel masts. If the bow will
point to the right, attach the yards so that surface A is on top.
If the bow will face to the left, attach so that surface B is on top.
Glue the yards in place at an angle, as shown in the illustration,
so that the model will resemble a ship sailing in the wind.
