Lymington · UK — Custom Yacht Builders

Built from carbon.
Proven by ocean.

Custom racing yachts, performance cruisers and structural composites — engineered to America's Cup and Volvo Ocean Race standards by an employee-owned team with 40 years at the craft.

[ 00 / Who we are ]

Two purpose-built facilities on England's south coast — a waterfront build yard at Hythe and a composite panel factory at Lymington — where racing pedigree meets aerospace-grade engineering.

We build custom racing yachts and semi-custom performance yachts of the highest quality — and we obsess over every gram of carbon that goes into them.

01 What we build
A CF-520 carbon IRC racing yacht
Grand-prix racing

Carbon racing yachts

Full pre-preg carbon hulls built for the world's most demanding race courses — from TP52s and IRC grand-prix boats to the Volvo Ocean Race fleet. Light, stiff, and engineered to win.

  • Pre-preg carbon
  • IRC · TP52
  • Water-ballast systems
  • Offshore-proven
B Performance cruising yacht
Semi-custom

Performance cruisers

Fast, refined cruising yachts that carry their pedigree below the waterline. We protect the weight saved in carbon by engineering the interior with the same discipline as the hull.

  • 30m+ superyachts
  • Lightweight interiors
  • Tripp · Frers · Carkeek
C Structural composite yacht superstructure
Structural composites

Structural components

Hulls, decks, superstructures and bespoke structural parts for other builders and refits — including fire-rated superstructures and complex one-off mouldings to aerospace tolerances.

  • Fire-rated builds
  • Superstructures
  • Refit & repair
D Composite panel factory CNC assembly
Series production

Composite panel factory

A dedicated facility for CNC-laminated flat and curved panels — core cutting, carbon reinforcement inserts and laser-projected assembly — bringing repeatable, production-grade composites to scale.

  • CNC lamination
  • Core cutting
  • Laser-projected assembly
02The approach

A step change in how light yachts are built.

"The weight saved by building in carbon is too often given away by a less-than-lightweight interior. We engineer the whole boat to the same standard."

04Heritage & ownership

Forty years of step changes — and we're not done.

The team behind Fibre Mechanics has shaped composite yacht building since the early 1980s: IOR maxis, Whitbread racers, America's Cup campaigns for Prada and Mascalzone, and IMOCA boats for Hugo Boss, Macif and Banque Populaire.

Founded in 2016 by the people who built those boats, Fibre Mechanics is employee-owned — a 68-strong workforce across Project, Production, Engineering and Design, split between our Hythe build yard and Lymington panel factory. Ownership is how we keep the standard exactly where it should be.

Employee-owned since 2016

Site 01 — Build yard

Hythe

Where the boats are built

Our waterfront construction yard on Southampton Water, with direct access to the Central Solent. A 38 × 55 m clear-span build hall and a hull oven for yachts up to 50 m — purpose-built to launch big carbon hulls straight into the water.

Site 02 — Panel factory

Lymington

Composite panel workshop

The original home of Fibre Mechanics and our dedicated composite panel factory — CNC lamination, core cutting, carbon reinforcement and laser-projected assembly, 12 miles west along the coast.
