Characteristics and use of your boat
5.1
General
The user manual is not meant to be a complete service or repair manual; it simply guides the
user to use his/her boat in a proper way.
5.2
Basic data
Recreational crafts can be constructed according to 4 categories (A, B, C and D)
under the Recreational Craft Directive 94/25/EC. This boat has been
constructed according to design category C. The meanings of the various
design categories are explained below.
Category A
:
The boat is built for conditions where wind speed can exceed 8
Beaufort (approx. 21 m/s), and where the significant height of the waves
(please refer to note below) can exceed 4 metres. In such circumstances the
boats are largely self-sufficient. Category A does not include abnormal
conditions such as hurricanes. Such conditions may be encountered on
extended voyages, for example when crossing oceans, or in coastal areas
where there is an open expanse of sea for several hundred nautical miles off
the coast.
Category B
:
The boat is built for conditions where wind speeds can reach a
maximum of 8 Beaufort (approx. 21 m/s), and where the corresponding
significant height of the waves (please refer to note below) is 4 metres at most.
Such conditions may be encountered on offshore voyages of sufficient length,
or on coastal waters when unsheltered from the wind and waves for several
dozens of nautical miles. These conditions may also be experienced on inland
seas of sufficient size for the wave height to be generated.
Category C
:
The boat is built for conditions where wind speeds can reach a
maximum of 6 Beaufort (approx. 14 m/s), and where the corresponding
significant height of the waves (please refer to note below) is 2 metres at most.
Such conditions may be encountered on exposed inland waters, in estuaries,
and in coastal waters in moderate weather conditions.
Category D
:
The boat is built for conditions where wind speeds can reach a
maximum of 4 Beaufort (approx. 8 m/s), and for corresponding seas (significant
wave height does not exceed 0.3 metres, and the height of the greatest waves
does not exceed 0.5 metres). Such conditions may be encountered on
protected inland waters, and in coastal areas during fine weather conditions.
Note
:
Significant wave height is a term used in boat design. In practice, significant
wave height means the average height of the highest third of all wave heights
measured in the waters. If the significant wave height is 2.0 m, the mean height
of all waves is roughly 1.2 m.
