This symbol shows where bow/stern thrusters are. Helps make boaters, dock workers, etc. aware of where they are to avoid any accidents from the wash/suction.

Even though the cort is running checked down on its runs lately to save fuel aren’t they using more fuel with the longer route that they have been running instead of taking the shorter route running checked down. I realize they are trying to extend the trip so they can keep running. Sorry to keep ...

Disclaimer, I do not have experience operating ships hands-on, but I am a naval architect/marine engineer that understands the working principle and am familiar with fleets on the Great Lakes, including many of the steam-to-diesel repowers that have happened.

While steam turbines themselves are ...

You'll never see a thousand footer shortened. The entire reason they exist is the economy of scale that their size provides.

To make myself clear, I am also very happy to see the Anderson being potentially activated again (although keep in mind she'll likely need a good amount of steel work and fitting out of a steam plant that's been dormant for several years - not cheap!). However, I have to agree that besides her one ...

Please don't take this the wrong way, as I know everyone is excited about the start to another great season, but maybe we should consolidate all posts about the start of the season? It seems like there's a new thread for every day, every ship, first to the locks, etc. which is kind of overkill.

Thanks Jerry, the idea I was going with is why hasn't just replacing the main boilers on steamers ever been considered instead of a total repowering? The majority of household electricity across the nation is generated by steam turbines, so that demonstrates the efficiency of turbines. It's ...

Yes, but this is because they are not subject to the Jones Act and were built overseas (much cheaper).

A new ship would be SIGNIFICANTLY more than $30 million - this high cost is one of the reasons you see old ships being rebuilt and no new ones being built. For example, the Buffalo cost $25 million to build in 1978. Taking into account inflation, that is just under $100 million today!
