Abstract

PURPOSE:To provide the sufficient effect of reducing rolling in low speed by providing a fin of a fin stabilizer having to upper and lower stages without elongating the blade length of the fin. CONSTITUTION:A hull rolling reducing fin 4 disposed to project sidewise of the shell 1 of the hull under the water is pivoted about a projecting axis 2 to reduce rolling. The projecting shaft 2 is provided on the end with a fin supporting portion 3 on which are juxtaposed two fins 4 for reducing the rolling of hull. The area of fin on which the lift is produced can be provided sufficiently wide so that the rolling of hull in low speed sail can be reduced without elongating the blade length of fin.
