I agree with lessons, but that cam be a limited option for some paddlers. Issues include finances, availability, time, or distance to the courses. At one point, I didn’t have the financial resources to even buy a kayak and gear, the time to attend, or the ability to assess the quality of the training. Even the information on the forum varies widely, yet I have no doubt it’s always offered with the sincere hope of helping.
Part of the pleasure of kayaking is the trial and error. I started out paddling canoes on mild whitecwater rivers. When I finally had enough money to buy a paddle boat, I selected canoes more for flat water for several reasons. Primarily because our old canoes got wrapped around obstacles. A sound option would be to take classes. However, I didn’t like shuttling cars, enlisting dedicated drivers, limiting the duration of a trip to a fixed course, or relying on water flow before scheduling a canoe trip. Besides, even if I had training, many of the passengers I took out had only a passing interest in canoeing.
An important question was presented to the OP: What style of kayaking do you hope to experience. Again, the advice is well intended, but at the point of my preparing this post, I’ve yet to see a clarification.
At the risk of being ostracized, I don’t mind pointed out that much of what I learned through trial and error has been challenged by far more experienced kayakers. Through the process of trial and error, I came up with different conclusions that work for me. Consequently, I’ve concluded that money spent on classes would have been wasted on me.
I can only suggest that if time and money is not a limiter, go ahead and take classes. Kayaking and canoeing really isn’t expensive or hard to get into, but much depends on each person’s goal and the environment. New paddlers should definitely learn recovery techniques, seek the company of paddlers with local knowledge about conditions, and at least research. Above all, read past posts.
