Girl With A Kayak

When kayaks are built by hand, it is common to use software systems to aid the craftsman to ensure proper buoyancy and displacement.
Configurations
There are several major configurations of kayaks. "Sit on tops", as the name suggests, involve sitting on top of the kayak in an open area. "Cockpit style" involves sitting with the legs and hips inside the kayak hull with a "spray deck" or "spray skirt" that creates a water resistant seal around the waist. "Inflatables" are a hybrid of the two previous configurations, these boats have an open deck, but the paddler sits below the level of the deck. "Tandems" are configured for multiple paddlers, in contrast to the single person designs featured by most kayaks. Tandems can be used by two or even three paddlers. How a kayak is configured has nothing to do with its classification. All configurations are represented in each of the five primary classifications.
