Glacier Boats of Alaska is proud to announce do-it-yourself (DIY) build plans for the Great Alaskan series of boats ...25-1/2 to 28-1/2 feet LOA, efficient, seaworthy, roomy, yet still trailerable without a special permit. They are all based upon the same hull, but have different cuddies, pilot houses, and arrangements (Prince Rupert - upper left, Newport - upper right, Rockport - lower left, Prince Rupert / Newport arrangements lower right.)   Basic specifications below...

Plans for the 26' Great Alaskan series of boats are now available so that you too can build your own hand-crafted boat, no special craftsmanship skills or tools required.

 Current status...

We receive a lot of requests for current status, builds, completed photos and the like ...Well, the first Great Alaskan has now successfully launched and several others will launch soon.  The best way to keep track of them is to visit our builders forums (see link above) and check the Projects board.  If you would like to contact one of the builders, please make the request through us and we will contact the builder for you to find if they are willing to share their contact information.  Otherwise, the builders forums are probably the best place for you to ask questions and to discuss ideas etc.
