The Cygnus GM21 is a sturdy inshore fishing vessel and work boat, suitable of single handed working and all year round use.

The design features include a high upright bow with a fine waterline entry, full round low bilges, full displacement long keel and transom stern. This combination produces a stable and seaworthy hull of exceptional quality. Working off a beach is easily done.

This vessel has become the accepted standard for many in shore fishing boats, with 30 years of production it is a very sea friendly vessel.
