Description

This application with rotatable and zoomable interactive 3D models shows how the relative position of lights and shapes changes according to the bearing.
The lights and shapes permit identification of any ships encountered, determination of the route and establish rights of way to avoid collisions. The application is divided into 3 parts:
- Official text of the rules
- 30 interactive 3D models with day and night views
- 50+ cards with graphic representation on the front and solutions on the back for recognition of lights and shapes

Bug fixes

Wording is wrong, lights questions unfair

Just paid £5.99 for this - the lights questions are very confusing, poorly worded and technically impossible.

Example: several flip cards show stern AND sidelights that you shouldn't be able to see in real life, even exactly at 112.5deg relative aspect. Have lots of officially approved paper flips cards and have never seen this before. If you're a beginner then don't use this as you won't understand where the errors are and will end up very confused when you come to your exams - or worse when navigating crowded seas at night for real.

Secondly, the wording is very poor and not precise. The answer to one of several being along the lines of 'a tug boat smaller than 50m with a tow smaller than 200m, skewed to port'

Official terminology should be more like 'Power Driven Vessel, less than 50m in length, underway, making way, towing, with the total length of tow less than 200m, observed from a port aspect'.

If you use this type of confusing and frankly incorrect language to try and pass any exams, leisure or commercial, you will not pass.

Disappointed.
