Panthera.2

Panthera.2 is a new double surfski-sea kayak hybrid – simply put a surfski with a kayak deck. But that would be an over-simplification. There is a small portion of sea kayak added to the mix, giving Panthera.2 slightly calmer movements in waves than an all-out competitive surfski. I expect the performance to be a tad less extreme than that of a thoroughbred surfski, but yet manageable should the paddler develop an acute desire to surf diagonally in high speed on large waves. I also expect a pair of competent paddlers to be able to keep Panthera.2 at speeds above hull speed á la surfskis off following seas.

Basically, Panthera.2 is so close to a genuine surfski that a rudder is needed to meet the potential (more about the difference here). An under-the-hull rudder with a surfski type of pedals is, of course, the best, but for fast touring, a rudder on the stern will do fine – preferably with one of the larger blades. With a full touring load, the kayak settles down to more directional stability for relaxed long distance paddling.

The plans show the original Panthera.2 at 680 cm LOA, but two shorter options are indicated on the lines drawing; 646 cm and 629 cm.

* These dimensions can be adapted to suit personal needs or wishes.
** Depending on type of wood, equipment, care with epoxy usage, sanding etc. etc.
*** The speed numbers are based on mathematical standard formulas (175 lb paddler + 30 lb carco weight) and corrected from the kayaks actual performance om trials, on tours and in races.
⁴ Calculated resistance in 4 and 5 knots (at nominal load capacity).
⁵ Initial stability and secondary stability on a subjective scale, where 1 is very tippy and 5 is very stable.

Plans

The plan sheets contain the information needed to build the kayak/canoe. Station molds, stems and construction details are full scale. Recommended cockpit size is shown full size. The plans show 680 cm LOA, but two shorter options (646 and 629 cm) are indicated. Lines and construction drawings are in metric scale 1:10. Building manual available on the website.

The illustrated step-by-step building manual is in Swedish only, but it is available online in English: it covers all steps in detail and will guide first-time builders through the project.
