Thanks Dennis.
Last week ,hauling out for the first time , I had a chance to use my electric winch.
It's a Warrior C4500 , mounted on the 50mm tow hitch and powered by the car's battery (engine running whilst hauling out). Nominally rated at 4500lbs , this reduces to less than 3000lbs on the third layer of the cable on the drum. The cable is 14 metres long.
The slipway , at Wells next the Sea , is moderately step with a good concrete surface. Parking the car , a BMW 318d , on the level , meant the trailer was c. 30 metres from the trailer , on recovery. Using the cable , strops , and 10mm nylon the trailer was comfortably hauled up the slip in a couple of stages . Chocks and the trailer brakes allowed the change from rope to cable.
On reflection , a straightforward procedure , keeping the car well away from the water.

After I'd done that I did wonder whether the gaff would have slipped inside via the forehatch.
Annoyingly the total weight of the car/trailer is such that there was still about 350kg to play with before the gross train weight was reached. The maximum recommended trailer weight for the car is 1600kg so the only way I could tow her without any legal risk is to transfer 180kg of gear to the car.
