CFD Online Discussion Forums - GMSH: Failure to translate .stl file

Hello all. I am new to cfd meshing and could use a little guidance regarding proper GMSH syntax and procedure.

Context: I am running a case of a vessel floating within a flowing river. For simplicity sake this is not a moving mesh. I have a larger background mesh which describes the control volume of the fluid. I need to import my .stl vessel and subtract that vessel from the domain.

Problem: After importing the .stl vessel I am unable to translate the .stl to the proper location within the mesh. For now the vessel is a rectangular prism. However, I will receive a more complex .stl later. Therefore I need to move the vessel from where it is imported (the local coordinate system of the .stl) into the proper place of the center of the background volume. I attached an image to reference here for further clarification.

Attempted Solutions: I first tried to use the GMSH gui and translate the vessel. I do not know why but the vessel never moved. Next, I tried to use commands by editing my .geo file. I tried to use the Translate command to move the Volume 1 and Surface 1. These are the correct tags because I imported the vessel first for this reason. For some reason this doesn't work. The vessel corner is still at 0,0 instead of my new location. I do not have any errors when loading the .geo file which would help me fix the problem. According to https://gmsh.info/doc/texinfo/gmsh.html#Transformations my Translate command should have moved the volume and surfaces, but it hasn't.

Any help is greatly appreciated. Thank you very much for your time.

Code:
For some reason I was unable to attach the geo and stl files. Instead, here is a copy of the .geo file. The stl is a ASCII file of a rectangular prism dimensions: 0.5,1,2.

Code:

SetFactory("Built-in");



Merge "vessel.stl";

Surface Loop (1)= {1};

Volume (1)= {1};
