Abstract
A roll stabilizer (10) is disclosed which comprises a fixed fin portion (12) connected during use to a hull of a vessel so as to extend outwardly of the hull in a substantially non-vertical direction, a flap portion (14) rotatable relative to the fixed fin portion (12), the orientation of the flap portion (14) relative to the fixed fin portion defining the degree of roll stabilizing force generated by the roll stabilizer (10), a shaft (16) connected to the flap portion (14) and extending during use through a vessel hull, a seal assembly (41) arranged to facilitate rotation of the shaft (16) while maintaining water tight integrity, and a first split bearing (18) disposed during use in a vessel hull on the shaft (16). The first split bearing (18) facilitates rotation of the flap portion (14) and comprises a first bearing portion (56), a second bearing portion (58) and operative bearing components (59), wherein access to the operative bearing components (59) and the seal assembly (41) is obtainable by separating the first and second bearing portions from each other.
