Broker's Comments

Simple, sturdy and seaworthy, this well maintained Colvic Seaworker 21 is looking for new owners.

Although basic in its navigation fit, this solid craft has a wheel house with over 6ft head room, 2 single berths, a large uncluttered cockpit/work area, a modern 20hp Beta inboard engine (& additional outboard!), new aluminium windows, a cockpit cover and a heavy duty full winter cover in good condition.

Capable of taking the ground with short bilge keels and beaching legs, this vessel has had light usage on the River Tamar & surrounding coastline over the past few years whilst being regularly wintered ashore.

Capable and substantial in its construction, this seaworthy boat could be put to many uses including fishing, diving, weekending and possibly even as a race control / committee boat. A great way to get out on the water with shelter from the elements if required.

These boat details are subject to contract.
Note: Offers on the asking price may be considered.
