The bizarre footage shows a bright pink light glowing in the distance.
As the boat moves across the water, the object seems to change shape while viewers raise their voices in shock.
The bizarre footage was posted by Youtube channel The Grimreefar, who claims this video is his “weirdest find ever”.
He said: “Whatever this was seems to change change shape and it looks like a massive energy, and towards the end what I’m seeing is the shape of a Viking warship.”
He also claims to spot what looks like “a Loch Ness Monster’s head” poking out of the water.
Although the video was only uploaded yesterday (November 21) it has already gained almost 2,000 views online.
Viewers are also baffled by the footage, with one person writing: “There are two strange objects in the water and the sky. What the heck is going on over there?”
Another astonished viewer commented: “This is hands down one of the most amazing videos I have ever seen.
“Unbelievable how much activity is going on.”
But others believe the strange light can be easily explained.
One person commented: “I don’t want to be boring, but I actually think this is a reflection of the sun.”
Just last week, a similar glowing object was filmed hovering about San Francisco.
