【實用教育app】Sailing Sound Signals Full|最夯免費app

This is the full version of sailing sound signals.

This is a fun app to help learn the common sound signals used during sailing.

The signals are based on the International Regulations For Preventing Collisions At Sea 1972 (amendment November 1995). To my knowledge this is the most recent edition and is used Worldwide.

This app is supposed to be some fun whilst also helping you to learn.

Enjoy.
