About Us

JWS Marine Services workshop at Southsea Marina

JWS Marine Services has built an excellent reputation for boat fibreglass repair and fabrication. Quality marine GRP work comes down to two things: thorough preparation and good materials. With more than two decades of marine fibreglass experience, we deliver consistently high-quality work.

We work closely with manufacturers’ representatives to keep up with the latest marine products and processes. Combining modern materials, careful preparation and years of experience means high-quality, competitively priced work for our customers.

The team

JWS was founded by John Shaw, who trained at the world-famous classic boatbuilders McGruer & Co in Scotland. John’s real passion is wooden classics, but the team works on GRP and wooden boats of every type, size and age, from jet skis to 46ft motor yachts.

Detailing and maintenance

We also offer a full boat detailing programme, from a simple wash down to a complete buff and polish. We can tailor a year-round plan that keeps your boat looking new and protects the paintwork and gel coat from the elements, so all you have to do is step aboard and enjoy her. See our maintenance services.

Where to find us

We’re based at The Boatshed, Southsea Marina, Fort Cumberland Road, Southsea, Portsmouth PO4 9RJ, with a 3,000 sq ft undercover workshop on site.
