This is a scratch build using plans from Brown,Son &Ferguson Ltd. plans come on three A1 sheets
which include hull profiles, plan and elevation views, and details of two types of paddles. A straight forward one and paddles fitted which an excentric mechanism. The latter is supposed to be the most efficient with the paddles turned to maintain max area to the water.
While researching found this web site with more detail. However the text is in German but it has loads of detailed drawings in PDF format.
Research showed that lots of these tugs were built in the late 1800, using the same design. My build was named because it was one of the last built for a Glasgow shipping company.
