Ritningssats, Hunter - 108 SEK
Most European or American built "Greenland kayaks" have been modeled on west coast designs. Many can trace their origin back to the kayak Ken Taylor brought back to Scotland in 1959. By that time the west coast kayaks were influenced – for good and bad – by the outside world. The east coast had been more isolated during what is sometimes referred to as "the little ice age" and when the eastern hunting kayaks were rediscovered, their forgotten qualities had a profound influence on the development of the modern Greenland kayak – the rake of the stems is greater, the sheer flatter, the flare of the sides has increased and the deadrise in the bottom is almost gone. They were faster, particularly against a headwind, more maneuverable and less affected by the wind than the west coast designs.
Hunter is not intended to be a replica. The construction method is wood-strip instead of skin-on-frame, the foredeck is 2" higher (I guess few paddlers would be happy with the 7" under-deck height of the original!), the bottom is slightly wider (since westerners are taller in general than the Inuit of 19th century, the kayak would have felt much tippier without the adaptation) and the chines are slightly rounded (giving a smoother stability curve and better water flow along the hull, without sacrificing the ability to turn by leaning). Despite these changes, I have tried to keep the beautiful looks and performance characteristics of the Greenland original.
This is a narrow boat (20.5" at the sheer, 18.5" at the waterline), but it is not scary to paddle. Initially tippy but with reassuring secondary stability, even novice paddlers quickly feel at ease (I would not recommend Hunter as a first kayak though – at least not unless you have ambitions and perseverance above the ordinary). The narrow width does make it easy to edge the boat with confidence when desired. The flat sides create a smooth and predictable secondary stability without the feeling that you will suddenly get dumped into the water.

The low aft deck permits the paddler to lean back with his head to the deck, making Eskimo rolls and many traditional braces easy. The foredeck is also low by modern standards (9.6" at the footrest) and is intended for those practitioners of Greenland-style paddling who prefer a truly snug boat. Sitting Eskimo style with knees slightly out and toes pointing slightly forwards, it is surprisingly roomy, even for large feet. Those who prefer a little more comfort might use the higher deck (10.6"), indicated by dotted lines on the plans. With its low deck, the boat is not adversely affected by the wind.
The kayak is very easy to maneuver thanks to the rockered keel, flat bottom, rounded chines, and comparatively short waterline. Leaning is a choice, not a necessity.
When the speed increases, the bow and stern waves climb the raking stems, rapidly increasing waterline length and as a consequence, hull speed and tracking. The results are the unusual double benefits of very easy maneuvering at low speed and good tracking at high speed.
What a fine looking AND handling kayak you've designed!! And fast, fast, fast...........
With a short waterline and a narrow hull, the wetted surface area and the frictional drag are small – not much more than a competition K1). The acceleration is impressive – a couple of strokes will bring you to maximum hull speed.
Overall, this boat is a lot of fun to paddle. With its relatively low volume, it is not intended as a multi-day touring boat - though traveling light and with a little packing discipline it will hold a surprising amount of gear. It is probably better suited as a day-tripping boat, with the high touring speed letting you explore a lot of shoreline in a day. It is even better for practicing rolling, surfing, rock hopping and playing in breakers off the beach.
Like the traditional boats of the Inuit, it is a versatile craft ready to take wherever you wish to go, whatever you wish to do.

³ Marschfart resp. motsvarande toppfart. Värdena är från början teoretiskt uträknade (Crouch´s formel) och justerade efterhand som jag kan göra relevanta praktiska tester.
⁴ Släpmotståndet i 4 resp. 5 knop mätt i kp vid angiven lastkapacitet.
⁵ Initialstabilitet resp. slutstabilitet – 1 är mycket rank, 5 är mycket stabil.
⁶ Deplacement är kajak + paddlare + last. Räkna bort kajakens vikt för att få lastkapaciteten.
Diagrammet visar beräknade stabilitetskurvor med en statisk last, och säger därför relativt lite om hur kajaken känns för en rörlig paddlare. Kurvan nära noll grader indikerar initialstyvhet (hur kajaken känns när den inte lutar) – ju brantare desto stabilare. Linjen strax till vänster om högsta punkten indikerar slutstyvheten. Ju högre och bredare toppen är desto tryggare känns kajaken att luta. Toppen visar också hur mycket kajaken kan luta utan att det känns instabilt. Kurvan till höger om toppen är svår att utnyttja – minsta misstag så slår man runt.

More about Hunter
Hunter is based on the east Greenland kayaks of the early 20th and is, like these, low, narrow, long with a straighter sheerline than the western types. My interest in Greenland started with trying a Greenland paddle and I got curious about the qualities of the Greenlandic kayaks and the possible combination benefits.
Hunter is very long (585-590 cm depending on the shape of the stems). But the waterline is comparatively short, just 491 cm. At low speeds, Hunter turns easily. I higher speeds, the bow, and stern waves climb the raked stems and the waterline length increases, adding speed potential and tracking. The narrow and short waterline means minimal wetted surface and very low friction. Acceleration is lightning fast – two or three paddle strokes to top speed.
Theoretically, the Hunter hull should have higher touring speed (low friction) but lower top speed (short WL) than fx Nomad, Najad, Njord, etc. Testing in different conditions show the touring speed potential, but also that Hunter is very fast off the wind by surfing easily and with control.
The narrow beam also (BOA 51 cm, BWL 47 cm) means that Hunter is a tippy kayak, with relatively low initial stability. Compared to an ordinary sea kayak, Hunter will be a challenge initially. But with solid secondary stability, the risk of capsizing is surprisingly low – capsizes occur when the secondary stability is overplayed, never within the initial stability range. Thus, even beginners will find comfort and security within a couple of hours. The real bonus with low initial/high secondary stability comes in waves – a stable kayak is a lot more affected by waves; Hunter moves vertically in waves, instead of rolling violently from side to side, as would a more stable kayak (the reason is that stability is just the kayak wanting to stay parallel to the surface). Hunter is furthermore more stable in speed and surfing when it sinks slightly down in its own wave system.
The planking is straight between chine and sheer and there is no rounding over at the sheer. The advantage is that the secondary stability is not compromised – high brace and balance brace are easy to do. The usual disadvantage with a sharp edge at the sheer is that the paddle stroke can't be as close to the center as with a generous rounding, but with Hunter's less beam and low sheer this is not an issue – even with a competitive high stroke technique the paddle is as close to the centerline as in most surfskis. There is simply no reason to sacrifice any secondary stability.
In speed, with bow and stern wave climbing the stems, whether by forceful paddling or surf, the kayak gains stability by sinking slightly down in its own wave system – an indication of how hydrodynamically sound the old Greenland hull is.
Hunter is very maneuverable. The flat bottom, the slightly rounded chines, and the short waterline mean that it turns easily and reacts directly to leaning sideways or front-back. It is, together with Black pearl, Njord and Frej my most maneuverable kayak.
Hunter is a low kayak. At the footrest, just 245 mm. It may seem low but it is normally comfortable for shoe sizes up to 43. For more space, there is a higher deck line (260 mm at the footrest) indicated on the plans. The Inuits of
On the prototype I tried a couple of new ideas that found their way into the building manual: a recessed cockpit rim – low, strong, elegant and easy constructed – and deck hardware after an idea of Gerald Maroske – also recessed and quick and efficient to construct.

The most comfortable cockpit interior I have built – foam plus camping mat. In three parts to fit together inside the cockpit and to drain water from the set. Note also the laminated-in miniature compass – handy when you forget to bring the compass.
Deck hardware – the Maroske line tubes. The wooden ball is to simplify storing the paddle.
To chose Hunter I believe you should have some paddling experience (or lots of ambitions and patience), and be interested in fast touring as well as surfing, rock-hopping and in developing skills in general.
Hunter – background and history
The East Greenland kayak found its modern shape later than the west Greenland types, but around 1900 it began to influence the kayak culture around the coast. Compared to the older types it was narrower, longer, with longer stems and straighter sheerline. With flatter bottom and more flared sides it was faster, especially on the wind, and maneuvered better. Initial stability was lower, but the secondary better. A more demanding kayak but with greater potential.
When English manufacturers in the 60th got interested in Greenland kayaks, it was the western type that was in focus, primarily the famous Illorsuit from the coast north of Disco Bay. This became the model for most brit-boats since then; Anas Acuta, Icefloe, Nordkapp, etc.
I chose to focus on the eastern type. Through references in books, I got curious about the qualities: they were rumored to be fast (especially on the wind), and easily maneuvered. When they were rediscovered, after the cold period that isolated East Greenland for a couple of hundred years, they influenced the development of modern kayaks all around the coast, but mainly in the kayaks for rolling competitions.
My Hunter, from 2002, is no historical replica. For a start, choosing wood strip is a major deviation. But also the deck height – no westerner could possibly squeeze in under an 18 cm hight foredeck! I needed at least 5 cm more room. And since westerners, in general, are taller than 20-century inuits I added a few cm beam for stability.
The name Hunter was chosen since those 20-century east Greenland kayaks were probably the most efficient hunting kayaks ever built.
