This module consists in two cradles with adjustable tilt and a vertical cradle, with varying heights, connected one another by sliding tie bars, chains and tensioners. Ideal for keel blocking in safety of any type of sailboat, especially those with delicate hull, where the weight is deployed on the bulb, on the shores and on the side-stands, reached by adjusting the strongest points of the hull. It’s made in three sizes for small, medium and large sailboats.
Depending on the length of the boat, 2-3-4 modules can be used.
