| 1. A rudder and dynamic trim adjusting apparatus for a boat, said apparatus comprising:
a rudder;
a rudder shaft having a longitudinal axis, said rudder shaft extending from said rudder and being rotatable about said longitudinal
axis to rotate said rudder;
trim fins extending from said rudder, along at least one transverse axis transverse to said longitudinal axis, said trim fins
being rotatable independently of said rudder; and
a mechanism connected to said trim fins, at least a portion of said mechanism concealed within said trim fins, said mechanism
being operable independently of said rotation of said rudder shaft to rotate said trim fins about said at least one transverse
axis without moving said rudder shaft, and wherein said rotation of said rudder shaft is independent of said mechanism to
rotate said trim fins;
wherein said at least one transverse axis is substantially perpendicular to said longitudinal axis; and
wherein said mechanism comprises a pair of transverse shafts, each said transverse shaft having a flat to prevent rotation
of said trim fin received thereover, with respect to said transverse shaft, respectively.
