I think the point, "what is the origin of the air raft," would be, where was the inspiration for an open anti-grav vehicle, similar in profile to a 'raft,' ie open, flat, shallow, low sides. The use of various anti-grav vehicles in fiction is abundant, and to my thinking somewhat irrelevant. It's the *design* of the vehicle that helps us determine potential influences from the literature.
In the Dumarest series, the *common vehicle* fits the description. Yes, occasionally there's mention of a bubble canopy that can be set up, but (a) that's the exception, and (b) it's a simple convertible top on what matches the vehicle description we're looking for.
FWIW, in Norton's The Last Planet, the Scouts use a grav sled of sorts that also matches the description.
