Help scaling a ship model

Hi. I have a ship model (Bryan Tam's Edmund Fitzgerald)
that is currently 17". The actual ship was 729'.
I want to rescale it so it is 1/250. I am not a math head. So hoping someone can double check me.

My thought is 729 x 12 = 8748" long.
8748/250 = 34.99" long.
So if I rescale the 17" model at 205.5% I will get 34.93".
Does my math sound right?
If not, what is correct?

Your math checks out.

One word of caution though. The reported length of a ship often refers to the length "between the perpendiculars" which is different from the length from the foremost point to the aftmost point of the hull. If memory doesn't trick me the length between the perpendiculars is the distance from the point where the stem crosses the construction waterline to the point where the rudder shaft does. Unfortunately, often it is not stated which definition for length was used. So, if you need your model to be exactly 1:250 you need to do some additional research. Good luck!
