There has been a slew of celebrity sightings in Maine this summer. Vacationland has seen its reputation trending upward for a really great place to stay for a few days. But while celebrities have been spotted at airports and eateries, there haven't been any sightings on the sea...until now.

Shared on Facebook by Jeff Grundy, the luxury yacht named "Blue Guitar" was spotted in Casco Bay on Sunday. According to Boat International, the yacht belongs to legendary guitarist Eric Clapton. To be fair, there's plenty of dispute on the internet as to whether Clapton has sold that boat or not. No concrete proof can be found.

The boat itself is still a marvel even though it was built more than 50 years ago. The 103 foot yacht was designed to accommodate seven people luxuriously, and clearly is still in terrific condition today.

So perhaps this still belongs to Eric Clapton and perhaps Mr. Clapton spent a day or two enjoying all that Portland, Maine has to offer. Perhaps this has a new owner and decided to hold onto the name that Clapton gave the boat.
