Which Cygnus Boat Is Right for You? GM16 vs GM19 vs GM21

Choosing between the Cygnus GM16, Cygnus GM19 and Cygnus GM21 is not simply about buying the biggest boat. The right choice depends on how and where you’ll use it, your space requirements and how you want the boat fitted out.

That is why a useful Cygnus GM16 vs GM19 vs GM21 comparison starts with the job, not the model number. The three established GRP designs can all be discussed around the intended application and local conditions, so the model is the starting point rather than the whole specification.

Use this table to create an initial shortlist, then confirm the final layout, equipment, operating category and certification requirements directly to us.

MODEL	CORE SIZE	SHORTLIST WHEN...	WORKING SPACE & FIT-OUT
Cygnus GM16	4.72m × 1.83m Draught: 0.38m	A small, capable boat is the priority. It is well suited to fishing on your own, everyday workboat use or leisure.	Smallest footprint in the range. Available as a hull main structure, commercial full build or a pleasure fit-out using marine-grade hardwoods.
Cygnus GM19	5.85m × 2.30m Draught: 0.53m	You want a flexible all-rounder for inshore fishing, workboat, tender, angling, leisure or another varied application, with more room than the GM16.	More beam and layout flexibility. GRP or hardwood cuddy and gunwale options; supply can range from hull structure to a fully finished boat.
Cygnus GM21	6.40m × 2.44m Draught: 0.76m	For an all-year inshore working boat, the larger deck gives you more room to work. The bigger wheelhouse also gives you more shelter and protection when the weather turns. It is a practical choice when space, comfort and dependable year-round use matter.	Largest dimensions of the three. Trawler-style or free-standing wheelhouse options, plus GRP or traditional hardwood treatment for the cuddy and gunwales.

Start With Five Practical Decisions

1. What will the boat be used for?

Begin with the main job: single-handed fishing, commercial work, harbour duties, tender use, angling, passenger operations or pleasure cruising. The Cygnus GM16 is a compact starting point for single-handed and lighter-duty briefs; the Cygnus GM19 offers broad all-round flexibility; and the Cygnus GM21 provides the largest platform and the widest wheelhouse choice of the three.

2. Where will it operate?

Think about more than where the boat will be used. Think about the water, tides and how far the boat may be from safe shelter.

Also consider where the boat will be kept, how it will be launched and recovered, whether it may need to sit on the ground at low tide, and how often it will work during the year.

GM19 and GM21 are stable, seaworthy boats built for inshore use. GM19 can also be fitted with hardwood bilge keels, allowing it to dry out upright. GM16 offers stable, seaworthy performance in a smaller and more compact boat.

3. How many people will be aboard and what will they be doing?

Think about who will be on the boat and what they will do. This may include the operator, working crew, seated guests or paying passengers.

Think about who needs shelter, where people will sit or stand, and how they can move safely around equipment. Access on and off the boat should also be considered.

Do not choose a passenger number from the boat’s size alone. The final number will depend on the chosen layout, how the boat will be used and the certification required.

4. How much clear working space is essential?

List the equipment that must remain on deck and the tasks that need uninterrupted space. Pots, nets, dive equipment, fish handling, tools, seating and storage all compete for the same area. The GM21 has the greatest overall length and beam, the GM19 provides a useful middle ground, and the GM16 keeps the package compact. A usable deck space will always depend on the final fit-out.

5. What level of fit-out do you want?

Choose how you want your boat supplied. This could be a hull to finish yourself, a partly fitted boat, a full commercial build, or a more traditional pleasure boat.

Think about what matters most for your use. You may want easy-care GRP or traditional hardwood details. You may need more open deck space, more shelter, extra storage or seating.

Also think about whether you need a cuddy or wheelhouse, and where the controls and other equipment should be fitted.

Cygnus GM16: Compact, Capable and Easy to Shortlist

At 4.72m overall with a 1.83m beam, the Cygnus GM16 is the smallest boat in the range. It is a robust modern development of the traditional Cornish Cove boat and is primarily associated with heavy-duty single-handed fishing, while also being used as a workboat, purse seine skiff and pleasure craft.

It is a compact boat that is easy to handle, with a hull that moves well through the water and feels steady and dependable.

You can have it as a hull main structure to finish yourself, or we can build it as a complete commercial boat. If you are looking for a pleasure boat, we can also finish it with marine grade hardwood joinery to give it a more traditional and distinctive feel.

However you choose to have it built, it is a practical and capable boat made to suit the way you want to use it.

Shortlist the Cygnus GM16 if:

1. Single-handed use and a manageable overall size are important.
2. You need a capable fishing boat or workboat without automatically stepping up to the larger hulls.
3. You want a boat that is ready to use, or one finished in quality hardwood for added comfort and style.

Cygnus GM19: The Flexible All-Rounder

The Cygnus GM19 is 5.85m long and 2.30m wide. It gives you more room than the smaller models, while still being easy to handle on your own. It is well suited to year-round use in inshore waters.

Its high bow, fine entry, rounded lower hull and long keel help make it stable and capable at sea.

The GM19 can be set up for many different uses. These include fishing, ferry and tender work, angling, diving, mooring work and leisure use. You can choose a GRP or hardwood cuddy, as well as GRP or traditional hardwood gunwales. The boat can also be supplied at different stages, from the main hull structure through to a fully finished boat.

Shortlist the Cygnus GM19 if:

1. You want more working space, but do not need to move up to the larger GM21.
2. You want a flexible boat that can be set up for work, leisure or both.
3. The choice of cuddy and gunwales matters to you, or you want to finish some of the boat yourself or need it to dry out safely.
