I previously owned a Toland 18-8 and it's a different boat that the 18' C-Dory. The C-Dory 18 is similar in design and construction to the "Classic" 22' C-dory Angler. The similarities include a painted fiberglass interior, lapstrake hull with accent stripe, cabin top with an overhang, but no bulkhead or door between the cockpit and the pilothouse. Think of it as the earlier version of the current 19' C-dory angler.
The Toland 18-8 was designed by Ben Toland. Ben left the family business to design and build his vision of a pocket cruiser. I understand that only 12 Toland 18-8's were built The C-Dory DNA is evident by the comparing the photos of the two boats. Both boats share a similar hull design and the classic pilothouse with a trunk cabin over the v-berth.
Unlike the spartan interior finishes of the C-Dory 18, the Toland 18-8 featured a bulkhead with locking door, a fully lined ("monkey fur") interior, a one-burner Walla cooktop/heater, ice box, sink with foot pump, and nicely finished cabinets with teak trim. The Toland 18-8 has a minimal cockpit, and this boat definitely favors cruising over fishing.
While beauty is in the eye of the beholder, both boats to me are very pleasing with the timelessness of their design.
