A short entry for a title which was revealed in a C64.com interview with Grant Harrison in 2015.
When asked about any titles worked on that never quite made it, Grant named Jet Boat Simulator, which was a sequel of sorts to Beach Buggy Simulator. Basically the same game, but just set on water – and no doubt a quick budget release to keep the money ticking over.
But as Gaz Spence (more awake than myself!) has found, isn’t this the same game as Turbo Boat Simulator? … http://www.gamebase64.com/game.php?id=8211&d=18&h=0
Seems like the same style, so could well be and Grant has forgot!
