IIRC the patchwork of laws, standards and regulations across the world for low voltage wiring is what restricted voltage in the 36 V – 52 V range. Some locations treating it as low, some as an intermediate and others treated it as high voltage.
It may be marine market specific, but several manufacturers limit to 36v for even high amperage motors because of it.
Obviously I=V/R will force this in the future though.
