The forerunner of the VERTUE class was the ANDRILLOT, designed in 1936 (specs above). Ten ANDRILLOT sister ships were produced prior to the outbreak of war in 1939. It was the fifth boat, EPENETA, that would ultimately give the class it's name but not until 1945.
Over the years, various alterations were made to the deck and rigging but the hulls remained relatively unchanged from the ANDRILLOT. Sail area for later boats were reported as 395 sqft (36.74 sqm)
The ANDRILLOT was a gaff cutter with a sail area of 366 sqft. (34.04 sqm). Changes to the rig and sail plan began immediately following ANDRILLOT from a gaff to a Bermudan rig to a "stutter" rig, a modified sloop and cutter. Other VERTUES were given a fractional rig. The most popular, however, was the masthead.
Most VERTUES were built by different firms in England. Cheoy Lee built a few in the late 50''s and early 60''s. Some were built later in FG.
It is thought that approximately 100 have been built to this design.
Beginning in the mid 1970's, VERTUES were produced using GRP and continue being built today by Bossom Boat Yard. See VERTUE II.
