Track Data
132
Beam tracks are typically used to span cockpits,
companionways and unsupported deck sections,
where fastening options are restricted or to avoid
the need for building additional support structure
into the boat.
Sectional and mechanical data, including moments
of inertia (Ix & Iy) and cross sectional area (CSA)
are shown below for the various beam sections.
Designer or builder should be consulted to determine
the appropriate section for a specific application.
Beam tracks for ball bearing cars are supplied
without holes. On request they can be drilled
with custom hole arrangements to suit
individual requirements. Contact our sales
team for further information.
