BAMAR BCPO hydraulic outhaul cylinder is a single acting pushing cylinder allowing for the immediate control of the mainsail base. Such system is more efficient and smaller than the classical pulling cylinder to be housed inside the boom with a pulley fitted abaft.
The cylinder body is made of black hard-cote anodized aluminium. The rod is made of stainless steel and has a bigger diameter in order to prevent it from bending when pushing. The cylinder will have to work with the car sliding on a track.
