About Sea Navigator
Sea Navigator teaches how sailors find their way. Latitude runs from 0° at the Equator to 90° north or south; longitude runs from 0° at Greenwich to 180° east or west; and a position is written latitude first. Read the positions of real ports such as London, Mumbai and Tokyo (to the nearest degree), and watch out for the trap answer with the numbers swapped.
Tap the map to sail to a position, choose the compass bearing that takes you from one port to another, and work out distances using the fact that one degree of latitude is about 111 km. In the route missions you tap turning points at sea to sail from Lisbon to Lagos around West Africa, from Cape Town to Mumbai, and from Sydney to Singapore, and any leg that crosses land runs aground.
There are three oceans with five missions each, including a hunt for a wreck from clues in an old log. Stars open new oceans and bigger ships, and every port you reach goes into your captain's log. The world map is a simple flat map drawn by hand, so it is good for reading positions but stretches the lands near the poles.
Best for ages 10+
