Description

The CS-18 is a small inshore skiff with flare reminiscent of the iconic Harkers Island work boat.  At a length of 18.5′ it will fit in most home garages and can be built as a tiller, side console, or center console.  This skiff is best suited for inshore and protected waters and is sure to attract a lot of attention at the sand bar!

This boat is built using cold molding and is recommended for those with some boat building and/or wood working experience. It is available as a pre-cut jig or full size patterns and both options include detailed assembly drawings.  You can find more info in our FAQ and watch an assembly video of the CS-21 (the sister hull) to this design to understand how the jig is assembled.
