$650.00$2,500.00

The CS-21 was inspired by the iconic Harkers Island style work boats. This center console design features the famous Carolina flare and a modified V bottom shape for a comfortable and stable ride while maintaining a spacious interior.  This boat is built using the cold molded method and best suited for those with boat building or woodworking experience.

Boat Plans include prints detailing assembly of the boat and full size templates to trace and cut all jig parts.

Jig Kit includes prints detailing assembly of the boat, plywood jig parts CNC cut, and HIN assignment.

NOTE:  Jig components include stringers, transverse frames, bulkhead and transom, plus temporary structure.  We do not include all plywood like the FRS series because hull side and hull bottom are cut to fit during assembly using the cold mold method.

Jig Kits are shipped by motor freight or can be picked up from Morehead City, NC.  Shipping will vary by destination and you should contact us for a quote before placing an order if you plan to have the kit shipped.  Some ball park costs from past shipments are ~$250 for South Carolina and ~$450 for southern Florida and Texas.
