A version of the anachronistic Lion with oil-fired boilers

As you might expect, the anachronistic version of the Lion, when given oil-fired boilers, is more capable. My choice is to mostly use the added capability to provide an 18 knot cruising speed for 5,700nm. I hesitate to give the ship a higher maximum speed, given the relatively low freeboard. This is the Springsharp report:
