About Pronautic

Built from experience.

Shaped by life at sea.

Pronautic was founded by Luka Kosem, a sailor and yacht technician whose understanding of yachts has been shaped by years of ownership, offshore sailing, restoration work and professional maintenance.

The journey

Rather than entering the industry through a traditional service background, Lukas experience was built from the practical realities of owning and operating a sailing yacht over long distances. After purchasing a 40-foot sailing yacht in Greece, he spent several years rebuilding and modernising the vessel before setting off on an extended voyage that would eventually span the Mediterranean, the Atlantic Ocean and the Caribbean.

Living aboard for years provides a different perspective on yacht maintenance.

When a yacht is not simply a weekend escape but your home, your transport and your connection to the outside world, reliability becomes more than a convenience. Every system matters. Small issues have consequences. Proper maintenance is not something that happens when a problem appears—it is an ongoing process of inspection, prevention and attention to detail.
That philosophy remains at the core of Pronautic today.

Following his return to Europe, Luka continued building his technical experience working professionally on sailing yachts in the 40 to 70-foot range, carrying out maintenance, repairs, commissioning work and seasonal preparation across a wide variety of onboard systems.

Today, ProNautic combines practical offshore experience with professional yacht care to provide owners throughout the Northern Adriatic with dependable oversight, maintenance and support.

A PRACTICAL APPROACH

Small issues become big problems at sea.

A loose line. A discharged battery. A minor leak. Equipment that hasn't been checked in months.

The purpose of Pronautic is not simply to solve problems when they occur, but to identity them before they become costly, inconvenient or safety-criticol.

Through regular inspections, preventative maintenance and clear communication, every yacht is menaged with a focus on reliability, transparency and long-term ownership value.

Clear assesments and practical solutions

Transparent communication. No surprises.

Consistent care that protects your investment.

WHY PRONAUTIC?

Experience that makes a difference.

There are many businesses capable of carrying out maintenance tasks.

What distinguishes ProNautic is the combination of practical sailing experience and technical knowledge.

Every recommendation is made from the perspective of someone who has depended on these systems offshore, maintained them personally and worked on them professionally.

The objective is straightforward:

To ensure that when owners arrive at their yacht. it is secure, maintained and ready for useside of a div block.
ABOUT LUKA

Hands-on. Straightforward.
Focused on what matters.

Pronautic is intentionally built around a simple model.
When owners call, email or request support, they communicate directly with the person responsible for the work.There are no account managers, service coordinators or layers between the owner and the yacht.
Inspections, maintenance planning, contractor coordination and owner communication are handled personally, ensuring clear information, faster decisions and complete accountability throughout the process.For many owners, that consistency is as valuable as the maintenance itself.When questions arise, there is always a single person who knows the vessel, understands its history and can provide a straightforward answer.If that approach aligns with how you prefer to manage your yacht, let’s talk.
