What a productive week of conversations and collaboration at Seawork 2026. Thank you to everyone who came to see us on our stand. We had an exceptionally busy couple of days and we know we were unable to talk to everyone. If you have any questions about how we can support your next project, please do get in touch with us

A huge thanks also to everyone involved in putting the show on - we're already looking forward to Seawork 2027!

The range of vessels on display at this year is impressive, including this extra special ship, which visited us on our stand today 🚢

Later this month, Graeme Lloyd is undertaking a fundraising walk from Bovington in Dorset to Portsmouth to raise money for Motor Neurone Disease (MND) Association and The Veterans'​ Foundation. We are delighted to support his efforts by using our 3D printer to make it a 'hull' lot more fun for him by creating a wearable Naval Frigate for the walk. We've also 3D printed an Army Tank for his walking companion.

Graeme, we hope it's all plain sailing and you stay buoyant during the walk!

If you see Graeme at the show today or during his fundraising walk from 18-24 June, be sure to say hello.

is underway and we're here all week 9-11 June 2026. Come to see us at Stand D28 in Hall 1 to ask our engineering team about our solutions for commercial vessels including:
- how we can help you to reduce fuel burn by up to 10%
- our options for rapid replacement Class S propellers in as little as two weeks.

You can also take a look at our our newest propeller design, the Sailfish, which can be seen in the Seawork Innovation showcase area in Hall 2.

The Sailfish, which is currently undergoing round two real-world testing with a number of custom and production boatbuilders, is 1.5%-3% more efficient than our existing highly-efficient CNC-machined, Class S MRK Revolution, Billfish, and MRKSuperprop propellers.

Using the science of biomimicry, we’ve designed the CJR Sailfish with a unique, undulated finish, which controls vortices by directing the water leaving the trailing edge and reducing tip vortex losses. This improved efficiency means lower fuel consumption and faster speeds for a given torque – maximising the engine’s power. The reduced trailing edge thickness also eliminates singing and reduces vibration without the need for an anti-singing edge.

To find out more, head to our stand or get in touch now.

Congratulations to , which has launched the first of a series of 16 Search and Rescue (SAR) vessels. We're proud to be part of this project, supplying complete sterngear packages to deliver the performance, reliability, and durability required for SAR operations.

Our bespoke sterngear packages, including fully CNC-machined Class S propellers, are designed and manufactured to ensure this series of 16 response boats:
- have a faster top speed
- consume less fuel
- are quieter
- experience lower vibration and cavitation

We look forward to continuing to support the team at Ares Shipyard and our project partners as the build of the remaining 15 vessels progresses.

Congratulations to everyone involved in the design, engineering, construction, and outfitting of the project. We can't wait to see the rest of this fleet enter service.

How much would a 10% reduction in fuel burn save your vessel or fleet each year? Do you need replacement Class S propellers fast?

Our engineering team is at on stand D28 from 9-11 June 2026 to explain how our bespoke, technically-advanced approach to design and manufacture supports our commercial vessel customers.

- Proven efficiency gains for a variety of workboats, including ferries, CTVs, windfarm vessels, and patrol vessels - up to 10% compared to standard rudders and hand-finished propellers
- Reduced vibrations puts less strain on sterngear system to increase vessel lifespan, reduce vessel downtime in repair, and provide better on-board comfort
- Class S propeller rapid replacement service in as little as two weeks - to get your vessels back in the water working sooner

- Complete sterngear package design and manufacture with ongoing technical support from our experienced marine engineering team.

Come to the stand or get in touch now to arrange a meeting and discover what can be achieved with our fully CNC-machined Class S propellers and flow-aligned rudders.

We look forward to seeing you there!

Congratulations to our customer on the successful delivery of their 55 Defiant NXT patrol vessel to the Massachusetts State Police Marine Unit.

Every detail of this build has been carefully considered to achieve optimum performance and we’re proud that our fully CNC-machined, Class S propellers are part of that equation. Designed to maximise efficiency, comfort, and overall performance, they reinforce the attention to detail that makes this boat, which can achieve speeds of approximately 30 knots at wide open throttle, exceptional.

Celebrating 'Sneak Attack's' first big catch just a week after launching with a new set of CJR Propulsion flow-aligned rudders, flow-aligned p-struts, and Class S propellers. We attended the first sea trials last week, which showed our sterngear upgrade, alongside new .engines, gained an extra 7 knots - but the proof is in the fishing!

Working closely with an expert team, including Brian , Cody at , Justin at , and Troy at , 'Sneak Attack' is now doing 41.5 knots at 2355 RPM

We're delighted to see another happy customer.

It’s no secret that our Class S Propellers with our flow-aligned rudders and struts can help you go faster and further …

Thanks for sharing how we have helped this 2023 Viking 72 Convertible achieve 47 knots with our flow-aligned rudders and struts.
