The Anas Acuta’s lines were originally developed from a kayak built by Emanuele Korneiliussen in Igdlorssuit for Kenneth Taylor in 1959. This kayak was measured and drawn by Duncan Winning in 1964 and those measurements have appeared in several places on the Internet. I had originally provided the lines of this Igdlorssuit kayak in a HULLS file, but now that FREE!ship is available, I’ve reentered the lines of this kayak.

Igdlorssuit Kayak

The year was 1959. The place was Igdlorssuit (Illorsuit is the new spelling). University student Kenneth Taylor was sent by his professor to study the kayak and Inuit culture. While there Emanuele Korneiliussen built Ken a skin-on-frame kayak. In 1964, Duncan Winning surveyed the kayak, and he passed along the information to Geoff Blackford, who modified the size. Geoff built a boat from plywood based on these modifications and named the kayak the Anas Acuta. In 1972, Frank Goodman started to commercially produce the boat. (source: Paul Caffyn, The Long Journey Home for a Greenland Kayak, originally published in The Sea Canoeist) Valley Sea Kayaks still produces the Anas Acuta.

The Anas Acuta spawned a wave of British kayaks, and according to a family tree compiled by Duncan Winning those include: Nordkapp, Skerray, Aquanaut, Pintail, Avocet, Q-Boat, Island Kayaks’ Expediton, Newt, Qaarsut(an exact replica of the hull in fiberglass with a modern deck), and Qaarsut 550. I’ve also heard that the Romany was based on the AA/Pintail, which would mean a number of other kayaks like the Meridian, Zephyr, Explorer, Alaw, Alaw Bach, Xcite, Xplore also descend from this kayak.

Duncan Winning’s family tree also lists 18 other kayaks that descend from the Taylor kayak. More info on the original.

Download Free Kayak Plan

• The plan is in FREE!Ship/Delftship format, and can be viewed with a free copy of the program, which you can download at DELFTship. The file is zipped.
• Updated and Developable Plans for Building: This updated (10/2006) file is much closer to the drawings than the last version. This is as close as I can get it with my skills and FREE!ship. The interesting thing is that very little fairing needed to be completed and by modeling to the drawing the boat became completely developable. No deck is included in this version.
• Cedar Strip Version: This is the model I used to build my cedar strip version of this kayak. After the build, I adjusted the model to account for building issues I encountered while building the deck.
• Stem and stations drawings, individual station plans, Linesplans, other drawings for this model are being hosted by Franck Vandamme. He is donating the 40mb of space required to host these files.
• Igdlorssuit_36×48 is a pdf of stem and station forms designed to be printed on a 36″x48″ plotter. These are provided by Pierre Côté of Sherbrooke, Canada.

Ilena paddles toward Artist Point in her new Iggy - a replica of Ken Taylor

Building Ken Taylor 1959 Kayak – the Igdlorssuit: Bryan built a semi-replica. Follow along in these articles. This is a replica of a kayak built for Ken Taylor in Igdlorssuit, Greenland in 1959. Originally built skin on frame by Emanuele Korneiliussen. Lines taken in 1964 by Duncan Winning formed the basis for the Valley Anas Acuta. This outlines the rational and decisions made to choose and start to build a new kayak. Included is good advice from several people who have paddle one or more of the traditional kayaks on the short list.
