Like any project, you can build a kayak quickly, or you can take pains with every step. While I am a big advocate of working quickly so you can get the kayak finished and start paddling, when I build custom boats for clients, I work with a bit more patience. This video shows some of the steps I took to make a bespoke kayak for a client. Many of the steps shown here are the hard way to do things.
I hope this video will inspire you to strive for beautiful results, but I hope it does not intimidate you into paralysis. You can make a beautiful wooden kayak yourself. It will take some patience, but even your inexperienced first efforts will be worthy of pride.
