Glen-L

This California-based firm was started in 1953  by naval architect Glen L Witt, and has produced designs for over 300 boats.  It has recently incorporated designs from long time associate Ken Hankinson. The family business is run by G;en’s daughter Gayle Brantuk.  It is supported by an extensive and well-developed website.

Glen-L offers boat plans and patterns to support construction, study plans for some of the larger vessels, fastening kits (silicon  bronze screws and nails), fibreglass kits (resin and cloth) for covering of structures, stitch and glue kits, sailboat kits (hardware, rigging and sails), and extensive supporting material (publications and videos).  There is also a wide-ranging boatbuilders forum.
