In case anyone will be visiting Maine anytime soon, I thought I'd let you know I found this cruise...it appears to be somewhat customizable.

Thanks Karen,
Just wanted to let you know that I found your message about the Maine Lighthouse cruise. I am going to Maine in September for five weeks and plan to do a lot of lighthouse chasing.
the Elms Bed and Breakfast in Camden also sponser Lighthouses cruises. I did one of these last summer when I was in Maine and I would recommend it to anyone. It was escellent! It was about six hours with a picnic lunch on board. We saw seven lighthouses from really close so we could get excellent photos.
