Plans, Alert/2 - 150 EUR
Purchase
Alert/2, designed in 1999, is a double with the same hull form as Alert. The size makes it faster, more stable, and even more comfortable in a blow. Unfortunately, it also makes it harder to handle. For all but a coordinated and determined team, a rudder would be a useful addition.
The plans show three deck layouts – two cockpits close to each other (best in a seaway), two cockpits with a cargo hatch or child cockpit between and one large classical open cockpit.

* 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.
⁶ Displacement is kayak + paddler + load. Count off the kayak weight to get the load capacity.
Plans
The plans show three suggested cockpit layouts: the standard configuration that is hydrodynamically best, two cockpits with a large hatch/child cockpit and the bold-style large cockpit.
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.
