Holding tanks

Does anyone know the capacity of the holding tanks on Grand Banks 49 Classic?

If it's rectangular, you can determine the capacity by measuring L x W x H in inches and dividing by 231 (cubic inches per gallon). If, for example the tank is 25 gal, the answer will be something like 26.876 or even depending on wall thickness...that's because a) you're using outside dimensions and b) not every single cu. in. in a tank is usable.

Or the tank might have a manufacturer's label on it...

Which may not have stuck to the plastic tanks. At least not after a few years. I don't recall any sort of label on mine.

Contact Grand Banks, they'd know what was in there new. I used their website contact form to ask a few things and they've been quite helpful.
