I like going out in boats a lot. And I like sketching a lot. Therefore I like going sketching in boats a lot.
Drawing from a boat presents multiple interesting challenges. For starters, you are always moving even when your sails are down and your oars are stowed. Your subjects are often in motion too.
Second, your eye picks up so much that is hard to translate to a pad of paper quickly, if at all. Observing details from far away while bobbing up and down is hard, but fun to do.
So earlier this summer when I went on a cruise from Olympia to Port Townsend, I decided not to use my paints and tried to capture the essence of each scene in pen and ink alone. Sort of like cooking, I created a reduction sauce on paper.
