The boat actually worked quite well for what it was. It rowed satisfactorally and moved right along with a trolling motor pushing it. It was just way too heavy for one person to handle out of the water. I may try building one using stitch and glue techniques someday. It has been permanently retired from sea duty and is serving as a sandbox.
Children seem to like the idea of playing on a boat, and some actually recognize it as one.
The picture doesn't quite do it justice but there aren't any of it in the water. The PK78 is the first boat I built that really worked right. It is about 8' long with over 4' beam, and can carry two adults or one adult and a couple of kids. It can be fitted with a sailing rig. It is very sturdy and should be fairly safe in choppy water if the operator is careful.
