Lead Keels for Superior Performance and
Stability
Lead is the best material for keels
It is denser (heavier for its volume) than cast
iron. Lead weighs almost twice as much per cubic inch compared to
cast iron. This means a stiffer, more stable boat and more efficient
keel (less wetted surface means less drag), while requiring far less
maintenance than other materials. Unlike cast iron keels, Catalina's
lead keels will not rust or require elaborate maintenance.
Catalina keels are cast from high quality lead
with antimony added to make the castings harder than lead alone, and
therefore less subject to damage from grounding. The keel bolts are
316-alloy stainless steel and are cast in place for strength.
Catalina lead keels are faired and epoxy coated.
