Rig-Rite has also built spars for many Traditional vessels and Catboats using Round Mast Sections. See Rig-Rite Round Mast Sections and Parts.

Most common Mast replacement parts are listed under the Mast Section that they attach to.

If you unable to determine which Mast Section you have from the details given on-site, we will require a tracing of the Mast Section with measurements.
