I have carried the trolley on the roof bars of a Ford Focus Hatchback; where the rear bar is similarly well forward, and the two relatively close together, virtually the same positions as your Golf.
Carriage isn't a problem, just a question of tieing down securely; nor would it have been with the boat on the trolley.
Loading and unloading however is.
You can't do it single handed when the rear bar is so far forward.
And though the boat and trolley combination is still light, approx 45 kg, and OK for two adults, when you add in spars in spar bag, sails, top & bottom covers, and possibly foils in bags & sails in the boat you are soon at a weight that though still within the carrying capacity of the car and roof bars is becoming a struggle for four adults to lift on and off.
The whole combination can be awkward to get adequate grip on for four people to lift from ground level to above head height.
This was my experience when I 1st tried transporting on the top rack of a Mersea stack trailer.
You may need to take the wheels off the trolley!!
I have seen roof racking done with the boat upside down, trolley on top, spar bag either inside or alongside the boat. That way they can be loaded & unloaded separately, and much easier for two adults. But the Aero is designed to be transported on a gunnel-hung trolley!!
Hope this helps.
