Because of its unstable accuracy, the Tucker type ship-borne wave recorder
has ot been used as a practical ocean wave measuring instrument. Tokuda and
Michida (1986) developed a new measuring system which uses digital data
processing. The total accuracy of this system was estimated by the following
two comparative experiments.
(1) A comparison based on visual observations.
(2) A comparison with a pressure type wave meter suspended under a drifting
buoy which was already calibrated.
As a result of these investigations, it was ascertained that the Tucker type
ship-borne wave recorder can maintain a stable accuracy when the new measuring
system is utilized.
