Track Sectional & Mechanical Data

 

  • 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 (Ixx & Iyy) 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.

     

    Typical Material Properties : σ yield = 90mpa (13.05ksi) / σ ult = 150mpa (21.76ksi)
