I have not sailed on the Horizon but I have played pickleball on the Panorama and the Celebration.

In other words, if the Horizon is just like my experience it will be more of a novelty than actually getting to play much.

What works best for me is to find the scan setting and hover the camera over the document until the scan option lights up and hit the fake shutter button. And voila, a clean image sans any corners or background.
