[scoundrel1728]

I would go for about halfway between Winnie's most recent crop and Cedric's. Still enough beach to add context and the diagonal line but removing enough beach to keep it subordinate to the real subject - the bits of structure offshore, especially the more distant platform. The more aggressive crop also puts this platform within reasonable distance of the lower right intersection of thirds and gets the horizon even farther away from dead center. Reducing the prominence of the beach also increases the effectiveness of the cantilever from upper left as a lead-in line.
