Thought I had posted in here a couple of days ago, but as Frank has said its usually the number of draws and the depth of the base that defines the difference between canal and match boxes canal boxes tend to have 3 or 4 draws whilst a river box will have at least 6, a good canal box will also have a removable base for those venues where you are only going to use the pole.
The likes of Rive and Milo boxes complete with all their add on gizzmos are perhaps best described as match boxes, but be aware they are not light and theres a few motors that you would struggle to get one in the boot
