Some designs use foam for bulkheads, the shape of which is often determined by trial and error, and then they're fitted after the hull is assembled. These are very difficult to seal and don't contribute much to shape, strength, or alignment as you build. Others use temporary forms which are removed after the hull is built. Our experience shows us that our built in bulkheads not only improve strength, but ensure accuracy and proper hull shape. Because they also stiffen the hull, they contribute considearble to hull efficiency making it easier to paddle.
Many people prefer to use a rudder.
For those that do, we include a complete rudder installation kit with every kayak kit. This enables the builder to install everything needed for a rudder as you proceed, when it is easier to install. This rudder installation kit includes plastic cable sleeves, clips to keep them in place, a foolproof and very neat method of installing the cable sleeves so that they will always remain water-tight and even a drilling jig to make sure that the holes needed are drilled in the right place and at the right angle. You can then easily install a rudder at any time you want to without any hassle. If you don't install a rudder the parts you've already installed won't show.
