Not more d**ned history! (3)

[John Parry]

Apart from the Trincomalee, there is rather a nice example of a paddle-steamer - the "Wingfield Castle" (1937).







Triple expansion engine...



And a scale model of her...



Spot the deliberate mistake....



(It's OK - she's a Finnish icebreaker !!)

And finally - any guesses what this is?



I should keep you guessing, but I don't know when I'll be back on here.

It's the lens system from a coal gas lighthouse. Pretty surreal hey?

John,

What was the purpose of the bow propeller on the ice breaker?
One would think it would be very susceptible to damage.

I assume that she would ram into the ice, then back off using the forward propeller together with the aft screw - maybe the forward prop would disperse the ice as well. I know that Canadian ice breakers have a sloping bow that rides up over the ice, and the weight of the ship breaks the ice beneath the bow. Don't know. I was hoping that Reijo would be able to tell us all about it!

Thanks,John.

Reijo do you know?

The bow propels diminishes the pressure under the ice, so it breaks more easily.
