Thank you all very much for the helpful advice, hints and tips. As it happened, my mainsheet
was laid over the throttle lever to be close at hand, but as I was on a broad reach and she was sailing relatively upright [for the conditions] at around 15 - 20 degrees, I was relaxing a little and enjoying the express train ride, although when I had been beating earlier she was on her ear, well off my scale, which stops at 35 degrees, and I was luffing quite a lot of the time to bring her more upright.
Sometimes the best way to learn is to go out in challenging conditions, but to sail as safely as possible, it certainly gives you confidence in the boat and you learn the little foibles and what you can get away with and what you can't.
Thanks again to you all for the trouble you've taken.
