Crowley #21 Tug -- HAMMS Plans


Here's a set sure to get Tim B. excited- Crowley #21, a 50 foot gasoline powered tug from 1912. I have the full HAMMS set for #21, and the outboard profile for the next set, Crowley #22... which appears to be same but for a few extra feet aft.

All of the same ilk as Bob Herrera's "Panama":

Cool, what's the story with the one on blocks?

The one on blocks was pulled out of the mud, pre-turn of the century I think, I will try to find the article again.

I always though what an amazing stern shape, and what a fine challenge it would be to plank a model of it ...

Is this one available in .pdf's? There was a member of the San Diego Ship Modelers' Guild who built an old gasoline-powered Crowley in a large scale so he could get in a lot of detailing. It was a beautiful model that made it on my "someday list."

For a picture and history take a look at a history of Crowley: Two Men at the Helm
PDF at http://www.crowley.com/content/downl...t+the+Helm.pdf
page 63 on the PDF [62 in the book enumeration] : discussion and picture!
Have to get Pat or Kay to scan and distribute.
Discussed these with Kay at one time, neat little vessel.

Good luck to all, it's a nice addition to any fleet.

Looking at the inboard section, and now understanding how the reverse gear works on these older engines, I can see that 21’s steering station has two wheels… the smaller one works the linkages for the reverse gear, while the larger spoked wheel would be connected to the steering chains.

There’s a second reverse wheel below.

The engine? The Crowley book mentions an Atlas-Imperial diesel in the WW2 time-frame, but this picture (showing as-built in 1912) is NOT an Atlas-Imperial. Probably not a Hicks either… anyone recognize it? It would be a gasoline engine in 1912.

OK, I'm betting on a Frisco Standard.

Tim,


How bad do you want a set of plans?
There are several of us that have those plans.
I know I have a set, and so does Mike R., who I hear might be coming up your way, to bring you something anyway.
I assume, you are coming over to Tug Fest, to watch the rest of us try and make fools of ourselves? I could bring you a copy, if Mike doesn't see you first.

Those will download and print to the same quality?
I know an "old timer" that worked for Crowley, I will ask him if he remembers what the original engine was. Also, capntroy might.

Very interesting!
Same naval architect as listed on the HAMMS plans... layout looks the same... compare the detail of the decking showing through the hawser rack aft. With minor tweaks, I'm sure they provided the same base design to multiple customers.

I'd work from those plans first... the HAMMS project sometimes measured old ships (in the 1930's!) for historical documentation... and sometimes, the HAMMS draftsmen merely redrew existing plans into the HAMMS format... as appears here. So why not work from the original?

The PDF labels the engine as an ATLAS. Apparently, Atlas and Imperial both made gasoline engines, then combined as Atlas-Imperial to make diesels when the Diesel patents expired.
