Sister Ships

[Guest]

Henry Ford II and Benson Ford? Close enough?

[TWilush]

Fitz and Homer differed mostly in their stern arrangement (coal vs oil fired as built), but they were close. They are still generally considered sisters as are the France and McWatters mentioned below; the length difference is immaterial to this effect.

Baie St. Paul (i) and Frankcliffe Hall (ii) also come to mind as do the Richelieu (iii)-Frontenac (iii)-Lake Manitoba and Elton Hoyt 2nd-Johnstown-Sparrows Point. The majority of the Vickers Class vessels with the possible exception of the Fairbanks powered Maplecliffe Hall are very similar and qualify as far as I'm concerned.

There are countless sets of sisters both American and Canadian, it gets more complicated when you consider classes of vessels derivative off the same or similar original plans (like the Davie and Collingwood built vessels in the 60's and 80's). The classic Tin Stacker fleet is another giant source; the list goes on.

The Morrell was virtually identical to the Townsand, but the were built at different yards. The Homer and Fitzgerald were identical to my knowledge. James Reed and D.G. Kerr. Argus, Hydrus, and Cygnus. Issac Scott and Charles Price. Middletown and LAT are pretty identical. I'm not sure about more modern boats.

Two of the best examples of sister ships would be (as built), the Imperial Collingwood and Imperial London.

What about the Daniel J. Morrell and the Edward Y. Townsend?

[RMartens]

The France and McWatters looked very similar but the France was approx. 7-10 feet shorter most likely due to the change in overall length permitted in the newly opened St. Lawrence Seaway.

Selkirk Settler, Canada Marquis and Saskatchewan Pioneer were sister ships.
The only difference was that the Sulzer engines ,although the same type were built by different builders.

fortitude and Sykes are Not sister ships. They may have similarities but they are not sister ships

[Denny]

Is the Algoma Quebecois and the Algoma Montrealais sisters? Were both of them built at the Canadian Vickers yard in Quebec?

I believe the J.N. McWatters and John A. France were sister ships.

The Munson and Saginaw are sisters.

John J. Boland [3] (Saginaw) and Detroit Edison [2] were virtually identical, Munson is of a slightly different arrangement but outboard profile is quite similar. Munson was a 1952 build, the other two in '53 and '54.

The Munson has a Bradley boom which is very different than the unloading boom on the Boland or Det. Edison.

Although the hulls on the Gott and Speer appear the same as other Bay Ship footers, they are built with higher yield strength steel for winter navigation.

Sister Ship
A sister ship is a ship of the same class as, or of virtually identical design to, another ship. Such vessels share a near-identical hull and superstructure layout, similar displacement, and roughly comparable features and equipment. Often, sisters become more differentiated during their service as their equipment (in the case of military ships, their armament) are separately altered.
The above are the requirements to be called a sister ship. I don't think some of the ships mentioned above could be called sister ships.

George M. Humphrey was a sister to Oberstar and Sherwin. All had same size, but Humphrey didn't survive. Drats.

What about some of the 1970's built Collingwood Shipyard vessels and self-unloaders with all aft cabins? I believe that some of them are or at one time were sisterships. The J.W. McGiffin which is now the CSL Niagara and the H.M. Griffith now the Martin I think were sisterships along with the Algolake. Although she once had a different bow design, I think the Louis R. Desmarais which is now the CSL Laurentien was once a sistership to the above mentioned. Also, not built at Collingwood but the Jean Parisien now known as the CSL Assiniboine may be a similiar sister to the ones I have listed above. One would have to consider three other sisterships the Birchglen, Spruceglen and the Kaministiqua when they were first built in the 1980's along with the current Mapleglen, Oakglen, Saguenay and Richelieu as well. These could all be considered as sisterships as well.
