- The steam powered liberty ship "S.S. Jeremiah O'Brien" in drydock at the Mare Island Shipyard, near Vallejo, California.
A tour of the exterior of the ship in drydock, tour of the steering engine room, and main engine room.
Stay tuned for the video of the voyage from drydock to San Francisco!

MAGNIFICENT!
That BOAT went thru a COMPLETE OVERHAUL 10 YEARS ABO.
BOILERS, everything.
A new ship
Richmond California.
Worked on these ships a lot in the sixties, a real work horse ....
Would have liked to have seen the shaft alley and the seal to the screw , never looked at it back then but other then that I’ve been all over them ...
Driving the steam winches was a real treat :)
Jon Jeter wow that must have been quite the experience, knowing you were working on the last of the reciprocating steam ships. Yes I have footage of "shaft alley" that will be going in the cruise video I'll be uploading soon. Thank you for watching!
YES shaft Ally is amazing. Went on her when in dock at SF. I got to see the shaft Ally. It's just a wonderful walk down the long shaft. The grease or oil points at each big support. The bridge was amazing with just round windows. The fly bridge is where they conned, is what the crusty old tour guy said. He said the helm guy better keep his ears open and watch the compass. You don't look out the window if at the helm station. It's amazing how British ships put their helm down inside the ship, the officer in charge stood watch on the fly bridge with very little protection from the elements. 😊😊
Thanks for the awesome tour! Amazes me that people designed these complicated ships so long ago, and even more amazing the men and women that constructed them.
xKmotx you're very welcome! Thank you for watching! Yes it's quite incredible, knowing they did it with slide rules, or even just long and! The craftsmanship skills lost to time...
Fantastic, I wish you could do an episode on how the Derrick's & Winches are powered and work.
Thank you.
I will be on her again in the future. Hopefully I can con the crew into exercising some of the deck equipment.
It’s great to see you and your dad checking out another ship. Just tell him that I don’t think he can fit that in his yard in case he’s getting extra ambitious. In all seriousness, I Wish I was there with both of you to look at that beautiful lady in drydock. The ship I most want to see in drydock being repaired is the battleship USS Texas. She has a wonderful history of her own.
TunTavernWarrior2 Thank you! Haha we may not be able to fit the ship... But maybe the main engine, if anyone had one laying around..
The reference video for visiting this type of engine room.
Well done ! 👍😉
Thank you very much! I am glad you enjoyed it.
Awesome tour hope to see more soon.
Shortribs Longbow thank you. The run from Mare Island to San Francisco is coming next
The guy in the red shirt is adorable.
Why is the rudder not perfectly aligned? great video just really puzzled
They were replacing the bearings for it top and bottom.
@@WesleyHarcourtSTEAMandMORE Ah, that makes sense, I saw the bottom post was lifted. Thanks
@@KPen3750good eye. You're welcome.
How did they get the ship so perfectly on the concrete blocks?
They have a drydocking drawing for the ship. They set up the blocks accordingly at a set distance from the end of the drydock. They then bring in the ship over those blocks, use multiple lines to keep it in place, and slowly let the water out of the drydock.
Wesley Harcourt thanks that’s really interesting
And what is the size of that propeller? Because I feel like the engine wouldn't have enough torque to turn that thing, or is it geared so the engine spins faster than the prop?
The engine drives the prop directly at a maximum of 76 RPM. Reciprocating steam engines have an incredible amount of torque. They produce their maximum torque at zero RPM. This one probably produces upwards of 1,000,000 ftlbs
How do they paint under the keel blocks?
According to the guys in the yard they don't paint under them... They just set them in a different pattern the next time she's drydocked and get the places they missed the last time. I was surprised.
Wesley Harcourt :thank you.
@@jimsonbrown9768 you're very welcome!
When they are talking about the cast steel bow piece, what's the forward hook on the bottom for?
I believe it was something to do with catching cables/lines and preventing them from fouling the prop... I'll ask more to be sure
@@WesleyHarcourtSTEAMandMORE 👍🏻 I was thinking that simple cause its not very pronounced. Id appreciate a definitive answer, but its just a curiosity so don't go out of your way
Thank you
