Cygnus Marine, Britain’s leading GRP fishing and workboat builders, first introduced this design in 1977, and since that date the CYGNUS GM21 has become the accepted standard for inshore fishing vessels, with over 300 craft being constructed. She is a sea-friendly, round bilge, stable, easily driven hull with a range of layouts to suit most applications and the capability of a sealed self draining deck. The craft is available to any stage of construction from bare hull shell to a fully finished to owners specification.
