Goodnow Kayak Free Plans

The 16′ 8″ Goodnow kayak is stunning. It’s lines flow beautifully and it begs to be built and paddled. At 17 5/8″ wide, I’d have a hard time fitting into it, so I decided to model the kayak for a possible upscale and build. Included here is the FREE!ship file for your download and some information about the kayak.

The Goodnow kayak appears in Mark Starr’s Building a Greenland Kayak book. Mark Starr and Kane Borden measured the kayak and Starr drew it in 2001. Mark writes a little about its history in his book: The kayak was collected on Robert Peary’s 1896 expedition to Greenland. It was used as a scouting kayak for the expedition and was built and paddled by Ludwig Sigurdson.

Kaper Numbers

Kaper is a resistance program used by Sea Kayaker Magazine to provide a baseline comparison between the efficiencies of various kayaks. These numbers are calculated using the same numbers as Sea Kayaker Magazine’s: 250 pounds plus a 35 pound kayak.

  • 2 knots – 0.832
  • 3 knots – 1.739
  • 4 knots – 3.253
  • 4.5 knots – 4.818
  • 5 knots – 7.351

Get the Drawing Package

The drawing package includes the full-sized study plan and each station and stem drawn separately on a PDF that prints full sized on ARCH D size paper (nestings). You can cut these out and glue them to plywood to cut full-sized forms. A pdf of the electronic drawing package. is available for this kayak. You can print the file on 24- by 36-inch paper on your own.

  • I have used Freeship to open the file. It was OK but it is impossible to “develop plate”.
    Is it normal?
    I want to try to buil this kayak and I need to use this function to prepare the plywood plate.
    Could you help me?

  • You’ll have to go into the layer menu and mark each plate as developable. You’ll notice when you develop the model, that there is major compression in places.

    It might make this boat a hard one to build in plywood.

  • Thanks for your help

  • Hello

    A french Goodnow is born…
    I did a test today on the sea.
    Nice boat, easy to roll, very fast…
    It was not so difficult to build it.
    My son make some photos. Of course It is his kayak.

    The next one will be for me, an Igdorllsuit.

  • Thats great. If you have pictures, please, post them!

  • Hello.

    I really want to build the Goodnow Kayak. But how do i print out the stations for stripbuilding in freeship?

    Thanks Andreas

  • The easiest way is to save a copy of the linesplan in dxf, then open it in a CAD program and print from there, because this will give you your stem profiles. First, specify where you want your stations. The second way is to export 2D dxf polylines.

    I’m uploading 3 pdfs. One includes the stations, and the other two include the bow and stern stems.

    Let me know how this turns out for you.

  • Thanks for very fast answer.
    I will let you know.
