This is a scow sloop I owned for many years. It was designed by Howard Chapelle who called it a "Utility Boat of the Dutch Type". The length is 22' and it is featured in Chapelle's book "Boatbuilding".  The boat was built in Haines, Alaska by a man  known only by the name of Manuel in the early 50's of  Sitka Spruce. Since then the crossplanked bottom was replaced with yellow cedar and I rebuilt the cabin top. The original builder did not rig it for sail. He used an outboard in a well and hauled gillnets over the transom. The owner before myself put the mast and rigging together. The rig is as Chapelle designed. The only difference from the original design is a 2' longer house.  The boat is now quickly deteriorating on the beach. It hasn't been the same since the current owner pulled the bow transom off with a pick-up in an attempt to move the boat up the beach. 
I moved the outboard from a well in the cockpit to the transom. This worked very well except when backing  hard you had to be careful or the outboard would suck the rudder in and grind the epoxy putty out of the often repaired patch.
Here is a good look at the sail plan. I taught myself to sail with this boat. 
A look at the cockpit
The mast was a solid piece of Sitka Spruce. It was unusual in that it had spiral grain. For some reason it had twisted as it grew. I don't know if this made it stronger or weaker.
