On the inside of my back hatch cover is a disclaimer sticker that says if you want to contact the manufacturer, they were in Blue Hill, Maine. The sticker lists a phone number of 207-374-2877. I have tried the number before with no answer. I also left a message with John Wigglesworth in Ohio, an apparently highly acclaimed kayaker who is loosely affiliated with the fiberglass business, and have had no return phone call to date. I have not found Mike Wigglesworth yet. I also spoke to the outfitters in Alaska that used them as a fleet, and they are trying to remember what happened to thiers, and where they got them. Gary
