6 Technical specifications

Terhi boats have consecutive serial numbers, a WIN
(Watercraft Identification Number) code etched into
the right side of the stern under the fender list. You
will need this number when you insure, register or sell
the boat. Referring to this serial number helps with the
delivery of correct spare parts and accessories. Check
that the WIN code on the warranty certificate corre-
sponds to that on the boat. Fill in the boat and motor
details in the boxes below for future reference.

Design categories:
Category C This boat is designed for use in condi-
tions, in which the wind speed does not exceed 6 on
the Beaufort scale (approx. 14 m/s) and the swell is in
proportion to that (significant wave height does not
exceed 2 m, see note below). Such conditions can be
found in open lakes, river estuaries and coastal waters
in moderate weather conditions.
Category D: This boat is designed for use in condi-
tions, in which the wind speed does not exceed 4 on
the Beaufort scale (approx. 8 m/s) and the swell is in
proportion to that (meaning a wave height of max. 0.3
m, with occasional waves reaching a height of 0.5 m).
Such conditions can be found in sheltered inland wa-
ters and coastal waters in good weather conditions.
Significant wave height is the average height (trough
to crest) of the highest 33 % of waves over an indi-
cated 12 hour period, which roughly corresponds to the
height estimated by an experienced observer. Some in-
dividual waves can be twice as high as this.
