See if you can spot the 10 differences between these two photos of a motorboat in the shadow of Tower Bridge

Every weekend MBM uploads two near-identical pictures. Your job? To spot the 10 differences between them.

Last week we presented you with two pictures of some of the security devices tested in January’s issue of the mag (out 17 December). You can download the solution, or see it on our spot the difference gallery.

This week’s two pictures are of a motorboat in the middle of London. Also in our January issue is a massive 11-page insider’s guide to the capital city. Download the pictures, or see them in our gallery.

Don’t forget to check back next week for the answers.
