Trimaran with manual control of lateral floats

摘要

The trimaran has a central hull (1) and two lateral floats (2,3) arranged either side of the hull. The floats are connected to each other by a single mobile arm (4) which can be moved w.r.t the hull, both transversely (in translation) and in rotation (oscillation about its axis). The translation of the arm and the way in which it slides freely in the hull is achieved through two pulley assemblies (6) each using two double pulleys.
