Coach roof/cuddy is detachable.

This from CYGNUS owner 'barklakemike':
"George Hinterhoeller in Niagara actually designed and built the first the HR 20 as he called it, in 1963. A class association formed in 1965 or 66 and the boat was renamed the Cygnus class. [Another early builder of the CYGNUS was Clarkecraft of St Catharines, Ontario].
The tooling was sold to Skene in Ottawa, (who also made Albacores); when Hinterhoeller became one of three boatbuilders (including Morch in Belleville and Bruckmann in Oakville) who combined forces to make up the manufacturing side of the new C and C yachts. ...the Cygnus was available with either a fixed cast iron keel and 2 ft 9 in draft, or with a fully retracting steel centerboard, when it weighed only 600 lbs."
Displacement for keel version: 950 lbs.
