The range of kayaks types is as varied as there are different bodies of water.
Hybrid construction could mean any method of building a boat which combines two different building techniques.
The successful design of any boat is a subtle blend of art and science. While there is a lot of room for personal preference and choice, there is also much that is constrained by the immutable laws of physics.
A description of boat design terms and how they relate to boat performance.
For those who prefer French, André Rose has translated this.
What could be easier than stability? Just make the boat wide and it will be stable … right? Yet, there are kayaks out there from 20" to 32" wide, all of which the manufacturers say are stable. After all, what manufacturer is going to say, "you need to be born in a kayak to keep this sucker upright"? How can they all get away with this? And what is "secondary stability" anyway? I know from personal experience that this question will provoke a discussion that can go on for days.
Guillemot Kayaks has been offering complete plans and instructions for building high performance wooden kayaks since 1993. Each kayak plan includes all the forms drawn out at full size and individually. No copying or lofting is required, just glue the plans to your form material and cut out around the lines. Each plan is printed out as an original to minimize any chance of errors being introduced in the reproduction process.
