Abstract
A fin bearing assembly for a fin stabilizer of a watercraft includes a shaft for driving at least one fin of the fin stabilizer that is disposed coaxially in a trunk pipe, and the fin is rotatably supported radially outward on the trunk pipe by at least two fin bearings. The shaft for the rotating driving is connected inside the hull to a drive unit of the fin stabilizer by a transmission of the fin stabilizer such that the shaft and the transmission rotate together.
