Engineering and Technical Services

Working alongside the world’s top boat designers and quality builders since the 1980’s, Gurit Composite Engineering has helped deliver quality engineering in the marine field.

We provide an appropriate level of involvement to suit the project needs & budget, ranging from basic advice & design sketches, through to concept studies to full engineering design, 3D CAD, FEA & construction drawings.

In addition to the main structural design we also design masts & spars, bowsprits & features such as retractable propulsion systems. Sustainability forms an essential part of Gurit`s global business activities. Our composite engineering services help transform traditional, heavier structures into lightweight, durable ones.

Gurit Engineering

For yacht refits we offer initial assessments of the job contemplated, on-site support as well as off-site design and analysis, as appropriate to your project.

Emphasising high quality, use of latest and most efficient design and analysis tools, we work for owners, owner reps and designers, building yards and operators.

Please contact our Engineering Team to discuss your project or any structural issue that we may assist to resolve or for more information visit our Engineering pages.
