Sue, I too am an artist, although I'm a studio painter. I do primarily oil
portraits and figurative works. You can see my paintings at www.michaelwitenstein.com
. I'm afraid I don't have any suggestions for you. My work is very tight and realistic. If I tried painting on the boat even at anchor
I'd have to convince my clients that their portrait was "cubist" on purpose.
When we moved aboard 3 years ago I brought my painting supplies, some canvases, a French easel, etc. but after a year I took them off the boat and put them in storage
. I have a friend who paints in watercolor when he is ashore and it seems to work for him. I've been contenting myself with taking photos for reference when I get back into a studio situation.
