Would it OK to put a bilge keel mirage 27 on a flat bed trailer and trailer it about 300 miles without any additional support provided to the hull?

Is the OP talking about a flatbed artic trailer or a close-coupled plant trailer?Displacement quoted variously 2199Kg to 2722Kg. Allowing 500Kg for the trailer, you need more than a large 4 x 4 to tow it. Probably a 7.5 tonner. More info here.
85% (or even 100%) rules are not "rules" but guidelines which have no substance in law. They are designed to ensure that the outfit will be stable (all other factors being equal). Exceeding this figure, whilst not illegal in itself, COULD lead to prosecution if the driver was stopped because of (say) instability or after an accident as there is a requirement on the driver to ensure the safety of his vehicle in the Construction and Use Regulations.
Usually a manufacturer will quote a tow weight which is far greater than the mass of the vehicle. Generally this is based on the total train weight (car + caravan) which can be started on a 12% gradient.
Where this weight (or any other e.g. nose weight) is given as lower by the manufacturer the user ignores it at his peril. Insurance could well be void after an accident - worse, the illegal combination could cause the accident if the towing vehicle is unable to handle it.
The big problem we have in the UK is the traffic density, especially on Motorways, which has caravans in close proximity to both cars and large goods vehicles, all travelling at speed. The vortices encountered can cause trailers to wander if not loaded correctly and matched to the towing vehicle.
