Con un grosor de medio centímetro en la pared del tubo y estando bien anclado, también soy de la opinión que no serán necesarios los tirantes. Yo había pensado colocar un tubo algo más potente, para rematarlo con un tramo final de 42mm de interior (simpre buscando el no tener que ponerle ningún cable adicional).
¿Como véis el planteamineto?.

Pues en algun sitio he visto yo una foto o dibujo con esa idea. ¿Estais seguros que sin tirantes? Son casi 20 kilos de aparato que debe elevarse casi 3 metros...
no se si estaria tranquilo sin tirantes

When mounting on a yacht or boat, positioning the turbine will be influenced by the configuration of the boat and other equipment fitted. It is important to ensure that the blades are at sufficient height such that injury to the crew from rotating blades is unlikely. A minimum height of the lowest point of the airblades above a crewed area should be 2.4 metres.
Also ensure that no part of the turbine can come into contact with any other part ofthe boat’s fittings or rigging. Because the turbine is subject to dynamic loads when the yacht is in a seaway in addition to wind loads, the tower should be securely braced or guyed both fore and aft and athwartships. The bracing struts or wires should be firmly attached to the main tower at a point 200 –300 mm below the lowest point of the blades.
The D400 is an inherently quiet and low vibration machine. However, certain applications may benefit from the introduction of anti-vibration mounts under the main tower and bracing struts. Note that, on a yacht or boat, no unsupported tower should exceed 2.5 metres in length. The wind loading on the D400’s rotor disc can exceed 50 kg, so any tower structure should be designed to allow for a safe working lateral load of 70 kg at the hub height of the turbine."
y por otro lado ¿como lo fijariaís a cubierta? ¿Simplemente dos planchas (ext e interior) con tornillos pasantes? Y a la exterior soldado el tubo?
