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 defunct 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

Description

• Free Linseplans: The free linesplans are station and stem drawings overlaid on each other. They are drawn at full size.
• Drawing Package: The drawing package includes linesplans and each station and stem drawn separately on a PDF that prints full sized on when printed on the right paper size, usually ARCH D. You can cut these out and glue them to plywood to cut full-sized forms.
