Nice clear footage Sue, you're getting good lens wash down from the ocean. When there's lot's of swell around it would help if you could elevate the cam higher by about another 300mm and the perspective of the ocean size will be more pleasing but still get the occasional lens clearing.

Notice how the dark colour SUP board tricks the GoPro auto exposure into opening up for more light. If it was a white board the image would be much darker.
