A difficult question to answer on the wheels.
It does depend on the offset of the wheels and the overall diameter of the tyres on those wheels, different wheel widths will affect the overall tyre height.
As for overall height, standard sizes are 30.5", if you check out the sticky on the wheels and tyres section, 265/70/17 are 31.5" and will fit fine.
You will need to do some research using online tyre calculators and consider that going bigger than 31.5" will mean trimming the plastics to avoid rubbing.
I know what you mean about boats, add the word marine to something and add a zero to the price.
