Here is an "artsy" sky and water version I did for fun of the 106 year old cement hauling freighter St. Marys Challenger sailing.

Very nice.

Lovely drawing of a lovely Laker.

I particularly like your bilge water effect!

Yeah, I thought it was a cool thing to add in. Being the lakes are fresh water, they draw water in directly for the boilers, treat it with water softeners to prevent calcium build-up, feed it to the boilers, and discharge it back into the lake after it re-condenses. Every hour of so the blow off any sludge or sediment from the boilers in a blast of steam out the side. Sounds like a jet engine if your near.

I would be rather surprised if that was the case. It's much more likely that they draw in sea water (Lake water?) and run it through the heat exchangers.
The other solution brings too many problems with it and it's too expensive in terms of fuel and water treatment chemicals.

Hi Thiel, At least that's what I thought was done I will be going on the ship next week for a trip. I will ask and find out for sure. I know when the water was drawn on board it first went into some tanks. They had bags of a white granular (looks like white road salt) "Dura Cube" product they pour in to disolve and then the water was fed to the boilers. You can see the bags stacked in this photo I took last year just inside the boiler room door...



Here is what I found about "Dura Cube":

A very oddly beautiful ship, serving a good purpose. Maybe we should buy her when her owners want to get rid of her.

Really beautiful. Reminds me of something from a Miyazaki film.
