| At its bottom side the boat
is equipped with
an essential element, which is the keel wing. This keel wing is mounted
approximately at half of the length, starting from the prow of the
boat.
The keel wing has a vertical and a horizontal component. The vertical
component
6 determines the distance between the boat's keel and the ski 7
which
forms the horizontal component of the keel wing.
The keel wing shows forms
which can clearly
be seen in the figures 4 and 5.
A side view of the keel wing
shows a form
which is rounded-off towards the ski 7 while seen in front
view it is elongated sharply towards the front. The middle
part of the keel wing broadens towards the backside. From an
hydrodynamic
point of view more alternatives of the keel wing than showed in the
figures
can be formed. The essential function of the ski 7 of the keel wing is
to lift the boat when the speed increases. The keel wing, at least
its
vertical component, plays an important part in the directional
stability.
The keel which wich
compared to the
whole boat, is very small in size, has been calculated and designed
thus
to have a hydrodynamic function, which brings the resistance of the
SKUA
to a minimum.
