Kayaking is a great way to keep fit and these racing boats are a great way to exercise. The marathon TK1 is a good dual-purpose design for use in sheltered areas.
Expect to take a couple of months to build one of these. The ply construction gives each craft a light but durable hull, while the strip plank K1 will be a little heavier than its composite production cousins.
The plywood racing kayaks are all built in 3mm thick marine grade plywood over timber longitudinals and ply bulkheads. The TK1 is available in two versions, the single chine marathon boat and the double chine racing boat.
The single chine K1 is a relatively stable version of this Olympic craft, while the strip plans round bilge K1 is much closer to the racing characteristics of this popular class.
