Camouflage
The camouflage indicates the catch with the wind of a Bateau or a Navire. This catch with the wind is particularly dreaded on a sailing going back to the wind because it affects its performances directly. Indeed, the phenomenon of the apparent wind , increasing with the speed of the ship, causes a fall of the performances by the speed brake being exerted on the dead works. The modern sailing ships, to the bulky and light hulls, can present a very unfavourable camouflage.
The Belem, at the time of its transformation in the sailing ship of cruising saw the volume of its superstructures increasing (by the addition of the living room of bridge) and surfaces it its lower sailss to decrease. The increase in its camouflage has, consequently, affected its performances of increase to the wind.
Camouflage is also a problem for large the ships sailing cargo liner light: their large Franc-bord associated with weak a Tirant of water returns little them operating in a Vent extremely; in the extreme cases, at low speed, a ship can be unable to keep its course and drifts then strongly. Certain types of ships are particularly handicapped by their camouflage: the ships carriers known as rho-rho (of English Roll one Roll off) and among the latter conveying of vehicles (Because Carriers).
