I've begun construction of a double ender in my Brooklyn shop, to lines from Walter Simmons. She has a flat keel, and will be planked from 9mm occume. 16 feet long. I've put up some photos on my blog, and will add to it as I go along. http://sailingskiffs.blogspot.com/
I've shown the trad. sprit rig, but will more likely go with a balance lug, and maybe even a yawl, but more on that down the road.
