That's good. I'll definitely have a go at the duck tack. You should try some fin first sailing Will.There are a few ways of getting to ff and a few to get back to orthodox. It can be a useful skill to save a lot of walking through shallow water.
For me Low wind is anything below 15 knots but the best for these tricks is around 8 - 12 knots. If the wind is too light you won't get the real feeling of the wind in the sail.
