This model was built from a model plan designed by Jim Picton.
I downloaded the plans from http://mypage.uniserve.com/~jpicton/jp-tug-1.htm
The modelplan was well written and easy to follow.
I added a base to the model that makes it lift slowly up and down as if in a gentle swell.
I used the small bushwheels from the elektrikit set, powering only the front set to give a realistic effect.
Jim Picton's original model in Red and Green
Mine built in Zinc, Yellow and Blue.
