"Many people want to capture photos for surfing, paddle boarding, kitesurfing, windsurfing and bodyboarding. The Sony ILCE-7RM2 is a good camera but needs an underwater camera diving waterproof housing to make it feasible for such use. More direct options include for instance the Sony HDR-AS200VR which allows you to record video and take photos with a splash proof body.
The Polaroid Cube+ records video and can take 8-megapixel still photos and contains a fixed 124-degree wide-angle lens. The GoPro HD Hero5 Black is a waterproof digital surf camera which mounts on your board or attaches via a chest strap or helmet. It has 4k video, and takes 12MP photos"
