NavioData is run by Dylan Wentink — a Chief Engineer with over 10 years on motor and sailing yachts up to +80m.
I've been the Chief Engineer who had to build the PMS database while simultaneously commissioning systems, managing contractors, and preparing for sea trials. I've spent weekends extracting maintenance tasks from OEM manuals when I should have been resting. And I've inherited databases that were so unreliable I had to start from scratch.
Why I Started NavioData
I've inherited bad databases.
Equipment missing. Intervals wrong. Spare parts that don't match what's actually onboard. Maintenance tasks mapped to systems instead of individual equipment. Tasks copied from a sister vessel with completely different machinery.
One of my greatest headaches was preparing for a 5-year shipyard period and realising I had to go through every manual and every spares box to work out what maintenance actually needed to be done, what spares we had, and what needed to be ordered.
What should have been done properly from the start ended up taking hours and hours — on top of running the vessel operationally with guests onboard.
NavioData exists so the next Chief Engineer doesn't have to choose between running the vessel and building the database.

Approach
This isn't outsourced data entry.
Every database is built by people with direct maritime engineering experience — not outsourced data entry teams. Every equipment hierarchy, every maintenance task, every spare part — extracted and structured by people who've done the job.
We deliver a complete data foundation: comprehensive equipment records, manufacturer maintenance schedules, and full spare parts catalogs.
What we don't do is make operational decisions for you.
Criticality ratings, minimum stock levels, task priorities — these depend on your vessel's cruising program, operational profile, and your own experience. A yacht running Mediterranean summers has different priorities than one cruising the Pacific.
If you want criticality classifications and stock recommendations included, we'll provide templates and work through them with the crew for confirmation — or send our recommendations for you to review and adjust.
Either way, the final decisions sit where they should — with the Chief Engineer and HODs who actually run the vessel.
Our job is to give you complete, accurate data so you can make those decisions with clarity, not guesswork.
