SPECIFICATIONS
DESIGN CATEGORIES
CATEGORY A
The boat is designed for sailing in winds that may exceed force 8 on
the Beaufort Scale and in waves of a significant height of 4 m and
more and the boat is to a large extent self-sufficient.
Unusual conditions such as hurricanes are excluded.
You may meet with such conditions when you sail long crossings, for
instance across the oceans, or close to the shore when you are not
protected from the wind or waves over several hundreds of nautical
miles.
CATEGORY B
The boat is designed for sailing in winds that may exceed force 8 on
the Beaufort Scale and in waves of a significant height of 4 m and
more and the boat is to a large extent self-sufficient.
You may meet with such conditions when sailing at open sea, or close
to the shore when you are not protected from the winds and waves
over several hundreds of nautical miles. You may also meet with
such conditions when sailing quite important inland seas which could
produce waves of this height.
CATEGORY C
The boat is designed for sailing in winds that do not exceed force 6
on the Beaufort Scale and in the corresponding waves (waves of a
significant height inferior or equal to 2 m).
You may meet with such conditions in exposed inland waters, in
estuaries and in coastal waters with mild weather conditions.
CATEGORY D
The boat is designed for sailing in winds that do not exceed force 4 on
the Beaufort Scale and in the corresponding waves (occasional 0.5 m
high waves at a maximum).
You may meet with such conditions in sheltered inland waters and in
coastal waters in fine weather.
NOTE:
The significant height of a wave is the average height of the upper
third of the waves; this corresponds more or less to the height of a
wave an experienced observer can assess.
Some waves will be twice as high as this value.
