Just a quick look at the picture of the Trailer Trawler 28 makes me doubt the "Pocket Cruiser" designation, and this is probably on the upper end of that size range, but its a "trailerable" design that probably relates well to the C-Ranger. Except this is designed for homebuild and plans are available.

This is a real "ship" for the size, at least in appearance.

Another design by Chesapeake Marine Design is the Puffin 28.
