Yacht

Durable high-quality products for the worlds yachting industry

With decades of experience designing and manufacturing exhaust systems for both motor and sailing yachts, Halyard understands the unique demands of the yacht market.

Whether for propulsion engines, generators, or auxiliary engines, every project is approached with detailed consultation and rigorous engineering, delivering reliable solutions that bring peace of mind to owners, guests, and crew.

Water-Cooled And Dry Exhaust System Solutions

We specialise in water cooled and dry exhaust systems and offer market leading aftertreatment solutions, including DPF and SCR packages for reducing soot and NOx emissions. These solutions support IMO Tier III compliance as part of a certified engine package. For environmental reasons, a DPF can also be installed solely to eliminate soot or as part of an SCR system for NOx reduction. Both systems are available for legacy or modern engines.

With in-house design and manufacturing, we have complete control over the entire process for our exhaust systems and components.

Designed For Marine Standards

With our extensive market experience, Halyard designs and manufactures products that meet Marine Classification Society rules and LYC and PYC regulations. Our composite, rubber, and silicone components are Lloyd’s type approved, and all Halyard products are produced in accordance with ISO 9001:2015 standards.

We offer a broad range of standard and bespoke components, all designed and manufactured by our in-house teams. Our supply covers everything from complete exhaust systems to individual parts. Whether you need a fully customised water cooled or dry exhaust system with aftertreatment, or a replacement spray ring, silencer, separator, hose, or bellows, Halyard delivers the right solution.

What our Customers Says

FAQ’S

Do Halyard design and supply full bespoke exhaust systems as well as components?

Yes, with in-house design and full system manufacture, Halyard can design and supply full water-cooled or dry exhaust systems to suit virtually any vessel. All that is needed is a 3D model/drawings of the engine room space from the engine turbo/manifold outlet and flange position to the intended vessel exhaust outlet position, plus the engine data sheet.

Can Halyard quote / supply a full exhaust system from pictures and basic measurements?

Generally, yes but would require at least a dimensioned sketch as a starting point. Once Halyard drawings are created full dimensions would need to be checked against the installation and approved by the customer.

Can Halyard replace a non-Halyard exhaust system or component?

Yes, we can manufacture using the existing equipment as a pattern to create a replacement or visit the vessel to measure for the replacement system.

Are there limits to the sizing of the exhaust components?
Yes, the system sizing is specified to each engine power rating, engine permissible back pressure limit and vessel configuration.
Can Halyard supply exhaust systems suitable for SCR / DPF installations?

Yes, we have developed systems and use materials compatible with the increased temperatures generated by aftertreatment equipment.

What material should I use for my exhaust hose, bellows, or connector?

Halyard can specify to suit the particular application and its position in the exhaust system. Higher temperature hoses are generally closest to the spray head/aftertreatment systems.

Can Halyard quote / supply from a picture of a hose?
We can normally identify the type of hose, but we would need to know the media, soft-wall or wire reinforced, the internal diameter, length, and length of any soft cuffed ends (if applicable).
Do Halyard supply an alert system to warn of overheat situations in water-cooled exhaust systems due to lack of cooling water?

Yes, we supply the Halyard “Exhaust Alert” system with both visual and audible alerts built into a standard 52mm diameter IP67 waterproof gauge and with fail safe functionality.

Can we program the Halyard “Exhaust Alert” system to provide a display on a vessel monitoring system?

Yes, the Halyard OEM Control Box will support this integration to a vessel display.

Will our exhaust alert display a temperature?

Our exhaust alert is designed as a temperature switch to alert to a cooling water flow reduction/loss at a set temperature, it is not a thermocouple to provide the temperature reading.

Can Halyard supply replacement thermal jackets to a basic dimensioned drawing/sketch?

Yes, we can supply replacement thermal jackets to a dimensioned drawing/sketch or normally from the original item.

Can Halyard support with an exhaust system installation?

Yes, dependant on the country location. Halyard has a service operation to support with installation, commissioning, vessel audits, fault finding, maintenance, repair or replacement for any exhaust system and not just Halyard supplied.

Can Halyard support with Seatorque or Aquadrive shaft system installation, service and repairs?

Yes, as a distributor for both the Halyard service team are OEM factory trained to offer full support for our distributed products.

Can Halyard support with Advantec Freeman hatches/Steelhead crane installation, service and repairs
Yes, as a distributor for both the Halyard service team are OEM factory trained to offer full support for our distributed products.
