The static and the navigable seem s the same, but have important differences, the navigable ones must be more robust than the static , details must be eliminated to be too fragile, it is necessary to value the fact that certain pieces are very laborious in their construction and in the first voyage or in the transport they can break.

They have certain points in common that they should be respected, for example to respect the scales and the historical rigor of the pattern.

For realization of a navigable or static model we should have the maximum of information of the pattern that we will reproduce, but for the navigable models, we need some mechanics and electricity knowledge that are indispensable for a good operation.

In the construction of the navigable one we have to build the interior of the ship, where we have to install the motor and the different elements that we necessary so that the ship navigates; axis, helix, motor and all the electric elements for its control like, battery, control of speed, sound units, generator of smoke etc., as well as the necessary ballast to get that the flotation line is like it indicates the plane, it is a very important point so that the ship navigates correctly.

For the construction of the navigable models I use different construction techniques, according to the characteristics of each pattern, the wood is the used material, but we must be a day and all the new materials that come out to the market.

The materials but common to build navigable ships they are, the wood and the glass fiber, with the two elements are obtain robust and waterproof ships, if the hull of the models must have a finish in wood, the glass fiber will be placed in its interior for not ruining the aesthetics of the hull.
