What is the range of the Galeon 440?

Could you please elaborate on the range capabilities of the Galeon 440? I'm particularly interested in understanding how far this vessel can travel on a single tank of fuel, as well as any factors that might affect its overall range. Additionally, are there any upgrades or modifications that owners can make to further extend the Galeon 440's range? Understanding these details will help me make an informed decision about whether this model is right for my needs.
