Internationally renowned boat designer revolutionises hydrodynamic hull performance with The Ultimate Boat Company

The Ultimate Boat Company (UBC) has launched a brand-new range of high-speed, best-in-class powerboats designed by internationally renowned naval architect, John Moxham.

Moxham, who is 86 (in 2021), has had an illustrious career in the marine industry, from designing military high-speed craft through to creating the UK’s fastest RNLI lifeboat (E-Class Mark I).

He was also at the forefront of using GRP for boats, designing the first mass-produced outboard-powered cabin cruiser, the ‘Microplus’ and is well-known for his work on high-performance designs for brands such as Avon, Ribeye, Scorpion, and now The Ultimate Boat Company.

This latest venture is, he says, “the pinnacle of my career”. 

Traditional Approach Yet Cutting Edge Design

For UBC’s pioneering portfolio of powerboats, John has completely redesigned the hull to fundamentally redefine the way a planing hull interacts with the water, positioning the company at the forefront of hull design and powerboat building.

The revolutionary and patented hull technology introduces a unique compression or hydraulic lift, resulting in vastly superior manoeuvrability, performance and stability.

Hydraulic lift is generated by modifying and then manipulating waterflow beneath the craft.

John’s designs, which always start life on a traditional drawing board before being converted to CAD, apply fluid dynamic principles developed for advanced supersonic aircraft to reimagine hull technology and hydrodynamic performance.

Major advantages

The hull improves waterflow across the propellors, increasing grip to achieve superior manoeuvrability and tighter turning with little loss of speed.

It also introduces a major practical advantage by enabling the helm to easily maintain a constant visual on the horizon through its linear transition onto the plane, derived by mitigating stern squat and associated bow lift. 

Overall, the groundbreaking design features deliver intuitive handling, exceptional seakeeping and greater directional stability.

Each of the new hulls has been designed for a specific application within UBC’s range of commercial craft, with all models optimised to deliver best-in-class features. The range comprises of; Professional (up to 10.5m), Coastal (up to 8.5m), Offshore (up to 16m), Seafari (up to 12.5m), Search & Rescue (up to 8.5m) and Tactical.

Sustainability without compromise

The material being used to manufacture John’s pioneering new hulls is also completely unique.

UBC is the world’s first boat builder to offer sustainability and unparalleled performance by using a sustainable composite material called DANU™ for its hulls.

UBC has been granted a license to manufacture with DANU™ by its patent-holder Exo Technologies, a next-gen development and investment company.

This super-strong material is less brittle than carbon fibre, twice as strong as fiberglass, and circular (no end of life) which means that UBC powerboats are built to last a lifetime.

Jeroen Wats, UBC’s Technical and Innovation Director said, “What John has done is to reimagine hull technology and hydrodynamic performance using principles that were first conceived during the development of the XB-70 Valkyrie supersonic bomber. This enables the boats to go faster, corner incredibly, and provide greater secure handling, stability and comfort.”

About us

The Ultimate Boat Company (UBC) is a team of perfectionists from different disciplines that came together for one reason: to exceed today’s standards for sustainability, craftsmanship, and performance in boating. The UBC team shares an ethos of innovation in every detail and a desire to build the best boats using the most advanced technologies.

That innovation starts with design. From trans-Atlantic racing yachts to RNLI lifeboats, UBC’s talented naval architects have decades of proven success. We design each boat for a specific purpose, including workboats with ergonomic and industry-leading deck space and sailboats with speed, agility, and balance on all points of sail. Each boat is created by UBC’s Master Craftsmen to exacting standards. Our skilled artisans work with every client to shape boats they’re proud to put their name on. In fact, they do – each boat has the name of the lead Master Craftsman on the UBC maker’s plate.

Our passion to innovate led UBC to the best possible materials. We’re proud to build hulls from DANUTM – a super-strong composite material that’s less brittle than carbon fibre and twice as strong as fibreglass. Using DANUTM, our power boats are built to last a lifetime. Each boat is also created with the circular economy in mind and can be completely recycled, upcycled, or re-manufactured. Currently, UBC is the only boat builder to offer the sustainability and unparalleled performance of DANUTM.

The UBC Foundation: Our commitment to sustainability is rooted in a shared respect for the environment. That respect begins at sea. We’re also committed to those who risk their lives to save the lives of others. Headquartered on the Isle of Man, the origin of the Royal National Lifeboat Institution, UBC directly supports the work of this remarkable organization. For every boat that we sell a donation goes to the owner’s chosen RNLI or independent lifeboat station. 

Intellectual Property: Our Moxham Hydraulic Lift© hull and use of DANUTM are patent protected intellectual property of the Ultimate Boat Company and Exo Technologies, respectively. These innovations are integral to UBC’s competitive advantages and help to define our brand. We’ve registered numerous patents to ensure those advantages remain secure. Non-disclosure and non-complete agreements, along with active monitoring, protect the Ultimate Boat Company and our partners. UBC’s clients can rest assured that our boats are unlike any other.     

Media: We’re available for interview by arrangement. UBC can provide expertise on the company; advanced naval architecture and engineering; sustainable manufacturing in the marine industry; and the advanced and patented use of sustainable composite materials, including DANUTM, in all UBC boats.
