No. Antennas that are designed to not need a ground plane can’t just have one added, it wrecks the design. I sell lots of marine radios, and fibreglass boats are pretty common. They also need antennas that can be attached to horizontal rails, that kind of thing. Most ground plane independent designs use half wave dipoles, often sleeved dipoles where the ground going part of the design is a sleeve that goes back down the coax to allow the cable to escape at the bottom, not the centre. If you had a real ground plane, you’d need to drill a hole in it, and lower the antenna into the ground plane to the point where the centre core radiator is no longer sleeved. Halfway down, usually. Pointless, and totally impractical. Some designs have the grounded side of the antenna electrically shortened with a coil, and in these the top section might be the usual quarter wave, but the lower section maybe half or a third of the length. It has a good enough VSWR but I’m not sure it radiates or receives as well?
If you design an antenna, you use established rules. Slapping on extra radiators of different lengths to increase bandwidth, or changing the ground plane from a solid vehicle roof to a few horizontal elements changes how the antenna performs. Sometimes for the better, but mostly, these mods make them perform worse!
