The keel has the shape of an I-beam. Due to this complex shape the
whole boat gains a better strength.
The inner part of the bow is made of an oak timber. To provide good
connection with the back bone (beam), a special part is made out of
eight thin layers of oak, shaped exactly along bow and backbone.

of eight thin layers of oak wood is shaped along backbone and bow. It
is covered with plastic foil to prevent it from being glued against the
bow or the backbone. Thus, it can be removed and sanded before finally
The afore mentioned part is sanded and glued against the keel and the
bow and bulkead A. Bulkhead A is closed now for security reasons. In
case of a collision the water may remain in the fore part of the boat.
The bow is reinforced by two pieces of wood. They will be shaped in a
way to fit to the hull.

sanded to provide good bonding.
Right: The box is completed now. For the necessity of the timbers, see
