About BoatPass

The person behind the app – and why it exists.

Founder & Developer of BoatPass

Hi, I'm Marius – founder and developer of BoatPass. Right now I'm studying for the boating license myself. And that's exactly how this app came to be: not on a drawing board, but out of my own day-to-day learning.

Why BoatPass exists

When I started studying, I asked friends who already had their license. Their verdict was almost always the same: there are apps with good content – but none that make studying on your phone actually enjoyable. Clunky menus, uninspired interfaces, questions you just memorize by rote.

That stuck with me. I've been building apps in my spare time for years – BoatPass is my passion project alongside my day job. My goal: an SBF app that genuinely feels great on a smartphone. Fast, clean, motivating. So I built it – and I'm studying with it myself.

What matters to me

Studying theory for the boating license shouldn't feel like a chore. You should enjoy learning and make fast progress. That's why every question comes with clear explanations and memory aids – instead of just „right/wrong“. The material sticks, and you get out on the water sooner. ⛵
