HOW THE VIDEOS ARE ORGANISED Seven categories: alongside, mooring lines and piles – each one casting off and berthing – plus anchoring. In the six manoeuvre categories, four videos each show the same situation in different wind conditions; for anchoring, four steps from the basics to berthing with a bow anchor. The first video of every category is free.

Port King Pro is a one-time purchase, not a subscription.

ALSO INCLUDED • German and English • Dark mode • Wall of Fame: when we implement a suggestion, we are happy to name the person who sent it – only if they want us to • Notifications only if you want them

DID YOU BUY PORT KING EARLIER? Port King was a paid app until August 2026. If you bought it back then, Port King Pro is unlocked for you at no extra cost – in most cases the app detects this by itself. If not, get in touch via More → Feedback.

Watch the manoeuvre beforehand – as often as you like, even on the pontoon just before you cast off.
