Following the development of the Core Sound 20 Mark 3 it seemed only fair that there should be an equally capable companion to the Core Sound 17. The CS-17 Mk3 offers the same design features as her bigger sister in a more economical package that can be towed easily by a compact car. A generous solo cruiser or weekend explorer, the 17 Mark 3 is the envy of all weekend adventurers and expedition racers.
A generous sail plan and low center of effort.
CS-17 Mark 3 “kit parts” shown above.
Available as a kit!
We have painstakingly designed the 17 and 20 Mark 3 kit’s to be built without any special techniques so that they remain within reach for the working boat builder.
"Great work on the design and CNC skills by the way, I'll never cut out another part again! Most fun I've had building a boat."

The plans set consists of 18 full color 11 x 17 sheets that detail all aspects of construction. Kit parts are labeled in each drawing referencing the kit parts throughout. The deck framing and Main Rigging sheet are available to view as a sample by clicking in the list below. We have taken all of the parts from the CNC kit and nested them in two 21’x24″ strips of mylar sheet that make up the full size templates. The sheets are taped together aligning the strike up marks to produce a templates sheet that can be used to transfer all of the part outlines onto plywood for cutting with a jigsaw. Recommended methods and sheet count are shown in the included detail sheet that accompanies the templates.
Note: This plans pack covers assembly only and does NOT include a lines plan or dimensioned parts. The plan sheets are designed to accompany the full size templates or the CNC cut Kit.
