The broadsides

The broadside-planks are primed.
According to their location, their profile is adapted to all the axes. Towards the stern, the broadside-planks are turned until to 90 degrees, shaped in the fire.
The width of every plank is varying in the length. Below, the length is reducing.
The assembly of the broadsides has to be done with accuracy.
The outer profile of the broadside-planks is adjusted in order to give them a perfect finish.
The exceptional flood of 1999 does not make the construction easy! The water was not arriving to this level since 1956!

The stern

The broadsides are ending on the sternpost, the principal upright timber at the stern of a vessel

 The keelson
The rear position of the motor does not permit to use the main keelson as a support. It is the reason why two keelsons are fixed on every side of this main keelson. Their bases are profiled in order to be adapted perfectly to the subjacent floor timbers of the transverse frame.
The two keelsons keep the block of the engine.
Crossbeams
Crossbeams are not carved straight, but curved. The curvature is constant so that a template is used for all the crossbeams. The curvature is helping to evacuate the water from the deck and above all to increase the elasticity of the piece of wood.
The crossbeams are carved curved
The three inner-side-timbers are putted one over the other, extending from bow to stern. They are assuring the transversal rigidity of the hull and support the crossbeams of the deck. It is in fact a variant of the inner-planking.
The assembly of the crossbeams which are fitted into the part over the inner-side-timbers.
The planking-section gives resistance to this type of assembly.
Installation of the deck-timbers, the flat, but thick gutter.
The longitudinal lumber, carved rectangular, is a curving frame along the broadside, 40 cm under the deck, and formed like the planks which are in the inner-side of the ribs-frame.
Watertight seals
Although the timber-frame of the border is watertight and the hull-wood, the black Itauba, is a dense wood which is nearly not moving during the process of drying, precautions are taken : A small groove with inside a slim cotton-cord is worked in.
Groove and watertight-seal
Tools for the groove and the watertight seal.
Cotton cord. The cotton is more sensible to humidity than the oakum.
The back timbers
The floor timbers of the stern are fixed perpendicular in the back extensions. The broadsides in the back have nearly an horizontal profile. The back, rounded by the vertical broadsides, is supported by the surrounding timber.
