odsalarka i zespół pomp hydraulicznych w maszynowni jachtu

Onboard hydraulics and desalination systems

The lack of drinking water in the middle of a voyage or a desalination plant failure in a remote marina is one of the most stressful scenarios for a boat owner. I service watermakers, freshwater, gray water, and black water systems, as well as bilge systems, ensuring safety and comfort on board.

Power generators

An generator that stalls at anchor or refuses to start in the morning can ruin an entire day of cruising. I diagnose and service Kohler, Onan, and Fischer Panda units—from the cooling system to the automatic start system (AGS)—to ensure the power supply works without surprises.

Electrical and electronic installations

Your electrical installation is the heart of the yacht — it determines whether the refrigerator, autopilot, and navigation will work when you need them most. I design, upgrade, and integrate Victron Energy systems, LiFePO4 energy storage, and NMEA 2000 electronics according to ABYC and ISO standards.

Supervision and coordination of shipyard work

"Modernization in the shipyard without engineering supervision easily turns into delays and overlooked details. I oversee engineering for multi-stage projects, verify subcontractors, and coordinate supply logistics, continuously reporting on the status and quality of work while organizing consultations with specialists, technical studies, and certification when the situation requires it."

Technical consultations, audits, and surveys

Before you sign a yacht purchase agreement or embark on a long voyage, it is worth knowing the actual condition of the electrical installations — not just what is visible at first glance. I offer pre-purchase audits, remote diagnostics, as well as Blue Water Cruising consulting and training for yacht owners in the field of yacht installations.

Unit retrofitting

Air conditioning in the cabin, LED lighting, electric winches, and self-generated energy from solar panels and wind turbines can significantly enhance the comfort of your cruise in the Mediterranean Sea. I install air conditioning and heating, photovoltaics, additional renewable energy sources, and yacht automation systems tailored to the characteristics of your vessel.

Supervision and care of the yacht during the stay

A yacht left unattended in the marina is not only at risk of dead batteries — it also faces broken moorings, worn fenders, damp interiors, or damage from sudden storms that no one will notice in time. I regularly check the condition of the entire yacht, the moorings, cleanliness on board, and the sails. I respond to weather changes and situations that require my presence on-site, and I carry out minor repairs immediately — including full winter protection and preparation for the season. Each time, I report the situation and create photographic documentation so you can relax at home.

Emergency quick interventions

Mobile service in Europe (Fly-In)

An electrical failure just before the start of a charter or during a cruise requires a quick response, not a queue at the local service — and sometimes a missing part that is not available on site. I can reach any location in the Mediterranean Sea and Europe quickly, bringing the necessary components, saving charters, and carrying out urgent upgrades.
