Description
Harbour manoeuvres without the stress – even with a crew of two. 28 narrated videos show casting off and berthing, mooring lines, piles and anchoring, explained by experienced skippers.
FREE OF CHARGE • 7 of the 28 manoeuvre videos: the straightforward case in every category • VHF radio reference: Mayday, Pan-Pan, Sécurité, radio check – based on SRC and UBI topics • NATO alphabet and a German/English/French glossary • Right-of-way and collision-avoidance rules, sea marks, distress signals • On-board checklists • Converter: knots, km/h and m/s with the matching Beaufort force, plus nautical miles, feet, temperature and weight • The complete blog with tips and tricks
Safety knowledge is not behind the paywall in Port King.
WITH PORT KING PRO • The remaining 21 manoeuvre videos: the same manoeuvres in stronger wind • Flashcard training: NATO alphabet, radio messages and vocabulary • The radio message generator: ready-made messages for your own boat • The in-depth articles on the Beaufort scale and sea state
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.
Each subscription will automatically renew 3 days before the expiration date for
the same time period. Subscriptions can be cancelled at any time before the renewal.
