Towing trailer and glider with a honda civic

I would not recommend assuming that a manufacturer "assumes".Â* When in
doubt, ask the manufacturer.Â* My experience in the auto industry,
involved with manufacturer's engineering specifications, indicates that
they have very stringent specs.Â* Give 'em a call.

I looked into towing with a hybrid. There is an issue with overheating of the electric motors on long grades. The 'recommended tow weights' are much lower for the hybrid version of the same model vehicle. I'd guess that part of the issue is that the same motors are used for 'regenerative braking' on the downgrades, so they don't get a chance to cool off.
Remember that manufacturer recommended towing limits are assuming a shorter wheelbase utility type trailer, not a long wheelbase glider trailer. Weight is not the only issue to consider. And they probably also assume short, local trips, not long-distance trips.

While I "typically agree", OEM limits are sometimes based more on "local sales laws" or "how likely do we think we will get sued?".

What may be fine in parts of the planet are banned in other parts of the planet, even if the basic hardware is the same.

As to the original question, well yes, this combination may be fine, but margins can be rather slim compared to other cars.

I have towed from a worn out '70's super beetle (with a huge plywood and steel trailer and a ASW-15 in it) to a mid sized motor home with a newer trailer and 15m ship.

Vehicle weight, the more the better.
Vehicle wheelbase, the more the better.
Trailer weight, the lower the better.
Tongue weight, small range of "OK".
Aero can make a difference, use the same trailer but on 2 similar vehicles but with different aero, some are great and some leave the trailer dancing at speed.

Road speed, hills, crosswinds and truck traffic can all make a difference.

Small cars with a AT and a heavy trailer, be mindful of trans fluid temps. Manual trans is a bit easier, all other things being the same.

When in doubt, slow the Frik down. If you lose it, damage is lessened, both the tow vehicle and the trailer.
Trailer damage is like aircraft damage, if you don't hurt it, you likely don't hurt peeps.

There is an SAE standard for recommended towing maximums. But the number of manufacturers that actually adhere to the standard has changed over the years. So it is difficult for consumers to compare the tow capacity of vehicles. It's interesting to read that the standard is based on a real world scenario.

By all means - call. But I can tell you that recommendations are based on an expected population of trailers. Glider trailers are the exception, not the norm. Utility trailers are the norm. The dynamics of glider trailers are much different than utility trailers.
Also, the accident-free history of a particular car and particular trailer does not mean that that combination is safe, let alone a broad spectrum of cars and trailers. All that it means is than an accident hasn't so far, and is no guarantee that it will not happen in the future. You may not have encountered the set of conditions that will push you over the edge. Losing control of a car and trailer at highway speeds is serious business. Personally, I will invest in a better tow vehicle before I will risk my - and other motorists who with whom I'm sharing the road - safety.
