General description

Lead is the heaviest of materials usually available. Its density of 11.3 g/cm3 makes it the ideal material for use as boat ballast.

By incorporating a lead bulb, the centre of gravity lowers and the distance between the centre of gravity and the centre of buoyancy grows, thus increasing stability. Alternatively, it ensures stability preservation with lower bulb volume and, therefore, less friction.


To request an estimate:

· Send a 3D drawing of the piece.                       
· Indicate approximate weight.
· Indicate antimony percentage (between 2 and 4%).      

Our bulb proposal:

If you do not have any drawing, we make you our bulb proposal, according to the kg that your sailboat needs.
