I am searching for a model cargo ship in HO scale (1:87) and have found several paper ship models that I like. These models are in PDF format and are 1:250 scale. I know I can use my local Staples to copy the drawings and need someone to confirm my math.
The formula I have is: 250 / 87 = 2.87 X 100 = 287%
I tried scaling up and down a model of a wooden boat, and it did not turn out quite right. talked to a naval architect and you cannot scale up or down drawings of boats and ships as they have to be drawn to a particular size, sailboats are notorious for losing their beautiful lines if they are scaled.
I think in a ship that small scale and reduced or enlarged will not make that much difference.
The math is correct, but I (somewhat) question the reasoning.
If the ship will be in the immediate foreground, then it has to be rendered in full HO scale. OTOH, if your ship will be behind and a bit away from the HO scale trains, 1/96 might be a better choice.
My reasoning is that 1/96 is a `standard’ scale, so things like cargo winches and capstans are produced in that scale. Rather like scaling a model building to use Grandt Line door and window castings.
There’s also the little (!) detail that ANY model ship is BIG. Saving a little size makes it easier to fit into the scene.
