HULL TECHNOLOGY

BUILT TO PERFORM

From the sketchbook to reality, the design of the 'Ultimate' concept embodies our clear vision for the future of safe and powerful boats. Boats that are visualised from inception for the application experiences of its users.

Ultimate Boats have adapted and engineered our design by learning from vigorous testing and worked to create better usability, easing human-to-boat interaction. From the Foam D-Collar to the High Gunwail Wall to the Self Draining Deck as standard. For Ultimate Boats the future is now. 

Built-in Scotland, Ultimate Boats are welcoming a new era of premium craftsmanship and showcasing the boat designs of tomorrow. See how we’re striving to make our boats more sustainable, our sea keeping experiences safer and our manufacturing methodologies even more intelligent.

All of our high-performance powerboat hulls come from the drawing board of renowned designer John Moxham. In his illustrious career, he has designed everything from high-speed craft for the Special Boat Service (SBS) to the fastest lifeboat in the RNLI, the E-CLASS (Mark 1). He was also a part of the design team behind the iconic supersonic Hawker Siddley Gnat fighter. Our revolutionary and patented hull technology fundamentally redefines the way a planing hull interacts with the water as a result of the ‘Moxham Retaining Rails’.

It applies fluid dynamic principles conceived during the development of the XB70 Valkyrie high-altitude bomber to reimagine hull technology and hydrodynamic performance. The patented ‘golden ratio’ and passive hydrodynamic performance modification system were developed to ensure that every craft is intelligently designed for its specific purpose.​

By modifying, and then manipulating waterflow beneath the craft hydraulic lift is generated. It also produces better quality waterflow across the propellors increasing grip which provides superior manoeuvrability and tighter turning with little loss of speed. Its major practical advantage is the helm’s ability to easily maintain a constant visual on the horizon through its linear transition onto the plane which is derived by mitigating stern squat and associated bow lift. In addition, this craft has a substantially lower attack angle to conventional hulls and its 25o deadrise means that it will slice through rough water without launching and limited slamming. Overall, it results in an exceptional hull with intuitive handling, exceptional seakeeping and directional stability.

SEAKEEPING

EXCEPTIONAL DIRECTIONAL STABILITY AND INTUITIVE HANDLING

The patented hull technology utilised in our high performance crafts has been intelligently designed to operate offshore in rough seas. It has a substantially lower attack angle compared to conventional hulls and the 25o deadrise means that it will easily slice through rough water without launching and all while limited slamming. It produces better quality waterflow across the propellers using pressure to increase grip which provides superior manoeuvrability and tighter turning with little loss of speed. A major practical advantage is the helm’s ability to easily maintain a constant visual on the horizon through its linear transition onto the plane. This is derived by mitigating stern squat and associated bow lift.

Overall, our boats will provide greater comfort in all weathers by delivering intuitive handling, exceptional seakeeping and directional stability.

CIRCULAR TECHNOLOGY

Built to last a lifetime using our patented super strong composite material DANU. DANU was created by our parent company, ExoTechnologies and is an alternative to glass reinforced plastic (GRP) with the goal of combatting the growing problem of old boats being disposed of via landfill, with an estimated 250 million kilos of GRP being dumped in Europe each year.
Comprised of styrene-free resin and sustainable fibres, this breakthrough composite material has exceptional strength and is capable of being recovered, recycled and reused repeatedly. It is stronger and lighter than fibreglass, less brittle than carbon fibre and costs no more to produce than either. The material loses none of its tensile strength when recycled and uses the same vacuum infusion methodology as many existing boat building materials, so requires no additional manufacturing or labour costs.

COMMERCIAL CONSTRUCTION

FOR STRENGTH AND DURABILITY

Vacuum  Infusion

Regarding composites, Resin infusion or Vacuum Infusion is a process where the voids of an evacuated stack of porous material are filled with a liquid resin. When the resin solidifies, the solid resin matrix binds the assembly of materials into a unified rigid composite.

What makes Infusion superior to other forms of resin applications is:

  • The Layup is done with dry-fibre so tailoring and ply layout is not constrained by resin gel time.  (So you can make it look nice!)

  • No autoclave or oven needed for curing.

  • High quality laminates with low void content.

  • Clean, worker-friendly layup process, you only mix resin once and don’t get it on you.

  • Consistent part-to-part quality and repeatable weight. 

  • Ability to laminate Hull, Deck, Wheel House and potentially stringers and other structures in one shot.

  • Production-friendly for moderate volumes.  

  • Easy to control  and train others once you have a system.
