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."
