the Cockle began life with a pair of Vee-twin Blackburne Tomtits. Ungeared and so limited to the maximum 2,400 rpm of the propellers, the Tomtits could only produce 16 hp (12 kW). It is not surprising that, when it came to the first flight the Cockle was underpowered. Before ...

Galvanic anode materials differ depending on the specific application and working environment. Steel structures, for...
Rough-toothed dolphins are smaller members of the dolphin group, reaching lengths of 8.5 feet. They sometimes express interest by approaching boats, and examining hydrophones and slow moving propellers visually and with echolocation.
