This game could have been taken from the TV series 'The Onedin Line'. It has all the same elements; buying a ship, sailing between ports, trading with the local inhabitants, and facing the rough elements of the seas.
The colour and the graphics are used to good effect to provide you with a map (different in each game) of your trading area. You start by buying a ship, provisions and cargo. In sailing between the four ports, you face a variety of hazards. It helps if you know something about sailing before you start; although I found the sea always got me in the end.
The program has a few rough edges which tend to spoil it. Some messages are untidy, and when you come to an untimely end, you are told the value of your estate, but the amount just flashes on and off the screen before you can read it.
As a business simulation and adventure game there would appear to be too much reliance on luck. A novel game, but the novelty of it soon wears off.
