Saucerlike object spotted over Irish Sea

I was on vacation in Dublin preparing to cruise across the Irish Sea to the Welsh Island of Angseley. While in the ferry I took a seaview video without realizing that I have indeed captured this UFO sightings. 4 months later b a backhome while viewing the video only realized that something odd is spinning in the skies. A saucerlike object kept spinning and hovering from north to west in the skies. I was so shocked and shared the video with my colleagues and even uploaded it on facebook.
