DESIGN CATEGORY

C a t e g o ry A
This 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 con-
ditions 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 nau-
tical miles.

C a t e g o ry B
This 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 mm
or less.
You may meet with such conditions when you sail on the open sea
or close to the shore, when you are not protected from the wind or
waves over several hundreds of nautical miles. You may also meet
with these conditions on an inland sea with a size sufficient to gene-
rate the wave height in question.
LAGOON 421
C a t e g o r y C
This boat is designed for sailing in winds that may exceed force 6
on the Beaufort scale and in waves of a significant height of 2 mm
or less.
You may meet with such conditions in exposed inland waters, in es-
tuaries and in coastal waters with moderate weather conditions.
C a t e g o r y D
This boat is designed for sailing in winds not exceeding force 4 on
the Beaufort scale and in waves of a corresponding height (signifi-
cant height of 0,5 mm or less).
You may meet such conditions in protected inland waters and in
coastal waters when the weather is fine.
• Note:
The significant height of a wave is the average height of the upper
third of the waves, that approximately corresponds to the height of
a wave an experienced observer can assess. Some waves will be
twice as high as this value.
