Oooohhhh, thank you for that photo of Zero, he's just soooo gorgeous! The aquamarine sea is beautylooks calm, with gentle waves, so I see Zero does t need restraining, plus he looks so intelligent and well behaved.
I used to sail off my local coast, western UK, it was a very rare day when the sea and sky were blue, usually dark choppy waves and cloudy sky! I loved it though, very bracing and invigorating.
