Why choose lead for boat keels and bulbs ?
A noble and dense material, lead has always been the preferred choice for keels and bulbs on racing and cruising boats. Thanks to its mechanical and physical qualities, lead remains the benchmark choice for enthusiasts of speed, safety, and reliability.
- High density (11.3 g/cm3) : this allows the weight to be concentrated at the bottom of the boat, lowering the center of gravity for increased stability and performance.
- Malleability and precision : lead lends itself perfectly to the complex shapes required by naval architects, allowing for optimal hydrodynamics.
- Durability and corrosion resistance : lead keels offer exceptional longevity even in the most extreme marine environments.
