Mechanical Workshop: maintenance and tune-up for your boat

Proper maintenance and tune-up of your boat are essential to ensure its performance and safety. The best way to achieve this is by trusting an official technical service, whether your vessel is new or pre-owned. For new boats, official maintenance is crucial to keep the manufacturer’s warranties valid.

When you sail, you need to be certain that your boat functions correctly: a breakdown at sea is far more complicated than on land, making regular maintenance essential for your safety and that of your passengers.

Oceanis

Key Advice to Get My Oceanis Ready

I bought a second-hand Beneteau Oceanis from a private seller, and it had many issues. I only have words of gratitude for Ángel Bosch for his support in preparing spare parts quotes. He gave me 10/10 assistance via phone and WhatsApp, offering valuable advice on some high-cost repairs.

Flyer 8 SUNdeck

The best Beneteau dealership

Without a doubt, the best Beneteau dealer in Spain, and for my work I know a few. They have the best facilities, and on a personal level I would also say that they are the best in Spain in service, speed and professionalism.

Oceanis Yacht 60

Complete Trust After a Lifetime in Nautical Life

After more than 30 years in the nautical world and having bought and sold a total of eight boats, Hermanos Guasch is by far the most professional, reliable, and skilled team I’ve ever come across. From commercial and technical advice to personalized follow-up during every stage of the boat’s configuration.

Excess 14

Exceptional buying and service experience

Two years ago, we bought our Excess 14 through Hermanos Guasch in Barcelona, and the experience has been nothing short of spectacular from start to finish. From the very first contact, the human touch was unbeatable. They accompanied us throughout the entire process in a close, professional manner, with an attention to detail that made all the difference.
