R/C Scott B. Tomlinson & R/C Great Laker
Launched on August 11, 2000 the M/V Scott B. Tomlinson is a representative of the typical design style of the more recently built vessels on the Great Lakes. In scale she is 1,004x105x56, a typical size for thousand footer currently sailing the lakes. Her exact sister, the M/V Great Laker, launched in June of 2001, follows the same pattern. Both models took about a year to be constructed.

They are propelled by a pair of electric motors that can be purchased at any Radio Shack store. Each engine is completely independent of the other. In other words one can be placed in ahead and the other astern at various speeds, a great help in tight maneuvering. This is accomplished by giving each motor her own Electronic Speed Control. The models are also equipped with bow thrusters. The bow thrusters are made by Graupner and can be purchased at www.hobby-lobby.com. The thruster, like the main engines, is given throttle control via an Electronic Speed Control. Power is provided by two 7.2-volt rechargeable battery packs. These can be found at most any hobby store or radio shack. The operator controls the model via an Ace Nautical Commander Radio. This radio is made for boat models like these that have twin propellers as well as a thruster. It can also be bought online.

The Hull’s interior framework is balsa on both vessels. The actual hull itself on the Tomlinson is made of birch plywood, the Great Laker’s hull is a thick balsa. A type of glue known as “seal-all” was used on both ships hulls. It can be found at most hardware stores. It is very water proof and thus a good match for a R/C boat.

Graupner bow thruster mounted in the Tomlinson.
The bow thruster is powered by 2 AA batteries (3 volts). The 7.2 volt engine battery was too much power and it ran to fast. The thruster is controlled by a speed controlled and the amount of thrust can be adjusted.

Sir Isaac Brock

The S/S Sir Isaac Brock is built to represent a 1950s style self-unloading laker. Her scale size is 649x65x35. Her angle iron boom is mounted forward, behind the bow cabins. The A-frame for her boom is typical of a laker of that era. Her bow cabins look like those aboard the M/V Calumet (Ex- Myron C. Taylor), but with a more modernized appearance. The stack and aft cabins are very typical of a 1950s vintage vessel, as they look much like the ones found aboard an AAA class ship such as the S/S Reserve. Her most unique feature is the style of her hull shape at the stern. It is very much a “Cruiser” stern, somewhat like one found on S/S Lee A. Tregurtha.

The Brock is propelled through the water by an electric motor that can be found at your local Radio Shack. Throttle is controlled via an electronic speed controller giving her operator the choice of how much power to apply in both ahead and astern. Four AA batteries supply power aboard the model. The operator via a two channel Futaba Attack-SR radio controls the boat’s throttle and rudder.        

The Brock’s internal framework is made of balsa wood and the hull itself is basswood. For hull glue “seal-all” was used, it is a highly water proof glue that can be bought at most hardware stores.
