Terhi boats have consecutive serial numbers, a CIN
(Craft 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
serial number on the warranty certificate corresponds
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 2m, 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 0.5m).
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.
