I was just interested as some of the shots were from a similar position as I was (roughly off Bradwell beach, opposite the Nass).
I did quite a bit of video here and above Osea Island later, I've set myself the challenge of seeing if I can get it onto U Tube & then here.
We picked up a mooring at Stone Sailing Club and followed on after the race, ended up anchoring off Osea for a bit the continued up to Maldon around HW.
Look forward to seeing your video.
