Oil tank placement between stringers

[SailorChlud]

Thanks, Terry:

I already have a hatch in the splashwell, which I use to access the bilge pump, inside-mounted transducer, and fuel filter. So I don't think the tank can go down in that space too. I have a second, house battery mounted inside my port locker (which was set up as a cooler when I got the boat. I would like to keep the oil tank in the starboard locker if possible.
