It is intended to lay down a solid foundation on which to build upon. Only years of paddling in varying conditions will make you an expert. The most important attribute a kayaker can have is common sense. This can't be taught, but time on the water and more advanced trips and courses will help. Because you can perform a self-rescue in flat water, does not mean you have the skill to do large crossings or rough water paddling by yourself.
Many beginners are very ambitious and want to head out into the open water.
Start slow and keep within your experience level. Paddle with more experienced paddlers and come on some tours. Join a club and learn from your fellow paddlers. After going on a few organized trips, take our 2 Star Training course. Each student will receive a 20 page booklet, which reviews all the information covered in this program, plus additional topics that time doesn't allow to be covered.
