Bait Shacks litter the Maine Islands. Some have been converted into seriously small homes or weekend getaways. My friends on Little Cranberry Island converted their bait shack years ago. Bait Shacks are long shacks on piers with a huge hole in the floor. Live bait was pulled out when needed. The Avery’s bait shack now houses one composting toilet, one bedroom and bed loft, a kitchen and living room with a back workshop office.
