Many thanks for posting these Owen
It is clear from this pic that the bird is a Grey-faced Buzzard - it did look very strange from the boat.
The skua is very interesting - I think it is an Arctic Skua with a an unusually well-developed breast band. There is not too much white in the upperwing, the body shape is not that heavy, and there seems to be a pale patch above the bill - all of these are good for Arctic, as is the pointed tail, but he bill seems to be pale with a dark tip, which would be better for Pom - and a breastband like this is more typical of Pom - so an interesting bird.
Cheers
