Marine Vessel Nav Lights

3 vessel light patterns are displayed but no vessel type to match with

Literally not challenging at all !! I had the not under command, not underway question 14 times out of 50. This app only shows a small portion of what’s out at sea and on the nav rules test.

And it worked the first time ….. but never again - kind dosent show the question anymore

Perhaps useful for someone with only limited knowledge of lights, but random, rather than considered construction of the questions makes picking out the right card trivially easy (I’ve just gotten bored at 100/100), the information provided about the vessels depicted is very limited and the difficult lights (e.g. submerged objects, WIG craft etc are missing completely) making this a very partial revision tool. 2 stars only because it’s fairly cheap.

This is just a quiz I wanted instruction e.g what are the different lights a sailing boat might display. Didn’t come up while getting to a score of 37

Very useful especially as once you have it downloaded it’s on your phone even at sea. Certainly a quick learning program
