A two engine F7F Tigercat dominated Carrier for about two years.
Multi-engine was effectively banned by a quickie "emergency" rules change that mandated a lethal penalty if ALL engines did not run throughout the low speed phase of flight.
It's hard enough to keep one engine running through low speed, let alone two. The winning Tigercat cut the outer engine means of a small fuel tank. According the plans and magazine article the inboard engine was allowed to run a full speed and the tip weight was seven ounces, thereby enabling some degree of hanging.
One-time stunts like landing a C-130, an OV-10 or a Piper Cub on a carrier, do, in fact, qualify the design per current rules, but they are a far stretch from intent of carrier-designed.
