The very detailed plan set is in PDF format tiled onto 61 Pages - this can be printed out on a home A4 printer to save on costs printing large sheets. Set paper size in the print options in the Adobe print menu - ensure paper size setting is correct. Think big - make a model Oil Tanker, this ship does the job of an oil production platform, it is a post panamax oil tanker size, a great project that will produce a unique model. This is a large scale model Alaskan Crab Fishing Boat project that was started in September 2012.
The free plans are for a 1:28 scale model of a fishing vessel that is similar to the Cornelia Marie Crab Fishing Boat featured in Discovery Channel's Deadliest Catch. The model was made using a foam core which was hollowed out after covering with Epoxy Resin and Glass Fiber matting. The Ballast used was concrete which was poured into the bottom of the hull after removing the Expanded Polystyrene Foam with a cutting blade and the remaining foam brushed with Acrylic Thinner to melt the foam. The concrete once cured and aged was covered with a coat of Epoxy Resin to provide a waterproof surface.


Powered by a 24v high torque motor run on 12v, the Model Crab Fishing Boat uses a large Octura x472 propeller that is normally used with a 26cc Zenoah Petrol Engine to power an RC Racing Power Boat.
Due to the considerably slower RPM than the prop is designed for, the power train only uses 2 Amps at full speed and propels the model boat way faster than a scale speed at full power. Floatation and ballast was checked and the hull loaded with dry cement and sand to achieve an approximate scale waterline with the power battery and motor installed.
The Devil is In The Detail, and the longest and most difficult part of the build project is the detailing. Painting the Model Alaskan Crab Fishing Boat - normal cans of Automotive Acrylic Spray Paint was used after preparing the surface with two good coats of primer. The paint work is protected by 4 layers of Clear Acrylic Spray which is lightly sanded between coats. When it's not battling wild autumn and winter weather fishing for crab on Alaska's Bering Sea, the fleet of boats featured on Discovery's reality hit "Deadliest Catch," which recently ended its ninth season, keeps busy with other fisheries. You will notice that the bridge superstructure is at the opposite end (bow) to a normal Tanker.


The Model Alaskan Crab Fishing Boat Scale Model weighs in at just under 17kg to give it a scale water line. A fair amount of Expanded Polystyrene Foam was left in place at the bow and stern to act as floatation should the hull fill with water. No specific reason for the choice of prop - I had one in my RC box and it pulled the right amount of Amps for the speed I wanted.
A little bit of overkill but when you have a large carrier bag full of burned out speed controllers, looking at extra amperage is far better than looking for it! The remaining ballast will be added at a later test to achieve the balance and correct waterline once the model is finished. I find the best way is a compromise and those extra little details can be added in between projects on a rainy day.
