The three mast types offered are custom made and enable an optimal system solution adapted to the type of ship and customer wishes. hydraulic foot outhaul system The hydraulic drive and the gooseneck bearing are connected with a cardan shaft to let the gear turn without any pulling loads from the luff rod system and to compensate any little misalignments. An easy to operate special length adjustment system to get the right luff rod tension is standard. This drive has undergone extensive development and offers maximum functionality, safety and longevity. The unique manual emergency drive is an essential safety factor in case of hydraulic failure.The Reckmann gear technology ensures that the inserted winch handle never carries any load from the sail. The low gear ratio means that you can furl the sail with just a few turns of the handle. The RMR system enables the mainsail to always be trimmed perfectly.
