I've used HT/AHT in anger on both moving and stationary yachts as HP didn't have references. C King also has a good point and a Hi- Line is a good way of helping to skin this cat.
Don't know about S92, but on SK3A you have up to 15 or 25kts depending on FPC mode (crab will correct me I'm sure) or on SK3 above 10kts you need to do it Doppler out.
