Rockabill Marine Design is a UK-based naval architecture practice specialising in work boat designs for commercial, offshore, and specialist marine operations. We design workboats that are shaped by real operational requirements, regulatory understanding, and long-term performance in service.
Our workboat design experience spans UK and Irish waters, supporting operators across offshore wind, aquaculture, harbour services, emergency response, and specialist government applications.
We design crew transfer vessels (CTVs) for offshore wind, marine construction, and commercial support operations. Each CTV is engineered for safe, efficient personnel transfer, consistent performance at load, and compliance with UK and Irish workboat regulations. Designs prioritise seakeeping, deck workflow, and crew comfort during repeated offshore operations.
We deliver aquaculture vessel and workboat designs for offshore and coastal farming operations, including harvesting and farm support craft. Designs focus on deck productivity, stability under load, and durability, ensuring vessels perform efficiently across long operational cycles in exposed marine environments.
Our landing craft designs support efficient transport of cargo, equipment, and personnel in coastal and nearshore environments. With a focus on payload capacity, deck accessibility, and operational simplicity, these commercial workboats are built for repeat daily use and reliable performance in demanding conditions.
Our commercial aluminium RIB designs support offshore support, crew transport, patrol, and specialist marine roles. Each RIB platform is engineered for reliability, payload flexibility, and all-weather performance, with configurations adaptable for emergency services and government use.
Alongside bespoke projects, we offer licensed workboat designs that are proven, build-ready, and available for immediate deployment or minor adaptation. These designs reduce lead time while maintaining the performance and reliability required for commercial service.
Our workboat design process integrates UK and Irish regulatory requirements from the outset, including MCA and MSO compliance. We support projects from concept through approval and construction, ensuring vessels are delivered ready for service, not just designed.
We design pilot boats and harbour workboats for safe and efficient operations in confined and exposed port environments. Hull forms and layouts are optimised for manoeuvrability, predictable handling, and high-frequency crew transfer in challenging conditions.
