I went to Machias Seal Island with Captain Andy Patterson of Bold Coast Charter Company http://www.boldcoast.com). He uses his 40-foot boat to take 15 passengers per day to the island. I boarded the boat in Cutler, Maine, and the 9-mile trip to the island took about half an hour. When we reached the island, we transferred to a smaller boat which was able to maneuver next to this concrete ramp. Landing is not guaranteed; if the ocean is too rough, you are limited to observing the Puffins from the big boat.
