I have just finished the build of a slightly modified Skerry. I purchased only the basic kit because I already had all the sailing hardware from a previous build.
The mast, boom, yard and sail are from a Shellback Dinghy, the rudder, tiller, daggerboard and misc. hardware came from an Oughtred Skiff that I built 13 years ago. The rudder required a flat transom for mounting the hardware so I cut 5" from the stern of the Skerry hull and fitted a flat transom. The conventional tiller passes through an elongated hole in the transom and has a tiller extension so that I can still sit in the center of the boat.
The sail can be rigged as a standing lug (shown) or as a balanced lug if I need to move the center of effort forward, the final arrangement has yet to be determined. The maiden voyage should happen later this week.
More photos will follow shortly. Google only likes to collect data, it does not like to share so getting my photos on to the forum is a chore.
Finally, I found a method that works. These photos show the flat transom arrangement and the "conventional" rudder and tiller instead of the push-pull rudder/yoke.

Laszlo, thanks. First launch is scheduled for tomorrow so I do not yet know how she will perform. The flat transom is basically triangular and the bottom corner is exactly at the aft, pointed, end of the bottom panel so I have not changed the waterline length of the original. The boat will be sailed solo most of the time and should never be aft-heavy as I will be sitting immediately aft of the daggerboard. Depending on the results of the first sail I may decide to add some ballast alongside the daggerboard case as many of the French built Skerrys seem to do. The first sail will also tell me where the center of effort of the sail needs to be located to balance the helm. The sail is 54sq.ft. and is currently rigged as a standing lug. If the COE needs to move forward I can rerig as a balanced lug.
I have been trying for several days to post additional photos but nothing is working. The photo in my initial post was copied from Google Photos to Flikr then the image address was copied to the forum but now that is not working for the other photos.
Nice looking boat, interesting approach. Do you notice any difference in rowing (flat transoms can be slower with an aft-heavy load since the dragging transom increases drag) or sailing (flat transoms can broach more easily in following seas than double enders). Or does the flat part of the stern stay above the waterline?
