| 内容記述 | The training ship NANSEI MARU (44.56 gross tonnage) is a wooden vessel, built in March 1967. In December 1972 the author had the ship fitted out with a Bilge keel (11.00m×250mm×150mm) and investigated into the effects of this Bilge keel on the maneuverability of the ship. The measurement was carried out through Z-maneuverability tests and turning trials to compare the maneuverability of the ship after fixing the Bilge keel with that before fixing. And the following results are obtained: 1) The results of Z-maneuvering tests show that the maneuverability index K’ after fixing the Bilge keel to the ship increases 10~20% and that the index T’ increases 50~100 % in case of small rudder angle and 10~40% in case of large angle, decreases, however, 0~20% in case of rudder angle 15°: that is to say that the turning quality gets better, the following quality becomes, on the contrary, worse (except the case of rudder angle 15°). 2) The results of turning trials show the same tendencies as those of Z-maneuvering tests that max. advance after fitting the Bilge keel becomes longer and max. transfer gets shorter. 3) The author would like to point out that there would be cases where the maneuverability of ships equipped with a liquid magnetic compass could not exactly measured, because, when a small ship sails with a high speed and turns with a large angle, the turning angular velocity becomes large and therefore the waked angle becomes too large for a liquid magnetic compass to mark the real of following. | |||||
