From the shopPlate III

Built by a chief engineer.

Tom Urbik has sailed as a marine engineer for twenty years, and has been a chief engineer since 2015. In 2009 he was third engineer on the Liberty Sun when Somali pirates attacked it with rockets. The crew barricaded the engine room, and nobody was hurt.

Steamer Power is what happens when twenty years of marine-engineering discipline meets a lifelong obsession with making small engines do unreasonable things. It works, it doesn’t break, and the math is right.
