See if you can spot the 10 differences in these two photos of Sealine's stunning new F46, tested for the first time in September's Motor Boats Monthly

Here’s something that might help you while away the hours until the weekend, MBM’s excruciatingly hard Spot the Difference game.

Just follow the link above to see if you can get the better of MBM’s art editor after he spent the best part of a day carefully deleting things from the bottom photo.

Every Friday we’ll post a new series of photos to test your observational skills, with the answers posted the following Friday.

The subject of this week’s game is Sealine’s stunning new F46, which MBM exclusively tested in our September issue (out now). To see photos from the boat test, check out our Sealine F46 gallery .
