Fotocean is a new app that allows you to exchange pictures with other boats that you see when youre out on the water.
You can see the positions of other boats, take a photo of them, and send it to them straight away - even if youve never met them.
And they can take photos of your boat, so that you can receive "selfies" of your boat on the water, in real time.
You can stop transmitting your location at any time by changing your profile.
