Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
New: the converter for knots, Beaufort, nautical miles and feet – free under “Useful”. Plus 28 narrated manoeuvre videos, VHF radio reference and sea marks.

FREE OF CHARGE

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

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.

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.
