The invention relates to an apparatus for attachment to a multihull boat,
the apparatus including a beam means substantially transversely associated
with at least a first hull and a second hull, the first hull and the
second hull being laterally opposed and each hull having a longitundinal
axis in the direction of travel of the boat, the beam means being
pivotably connected to a first hull or adjacent a first hull to allow for
horizontal rotational movement of the first hull, the beam means being
pivotalbly connected to a second hull or adjacent a second hull to allow
for horizontal rotational movement of the second hull, and wherein the
beam means is adapted to allow the first hull and the second hull to pitch
independently of the other.
