We crossed the 30 degree parallel (latitude) early this morning and that's always something to feel good about. It's probably more psychological than anything, but it does tend to be where the weather systems start to change with the influence of the high latitude weather systems making way for the tradewinds which grow in domination as you approach the tropics. Talking of the tropics (which are still 360 miles to the north), it is getting a little warmer. We're still wearing several layers and our full wet weather gear at night to keep warm, but the days are definitely a little warmer. So we must be heading in the right direction!
We have the hydrovane/autopilot combination steering, as we perfected last year, but with a slight difference. The autopilot is still set on it's least responsive mode and the hydrovane is set to steer within the bound of the autopilot's limits. So the hydrovane steers the boat, boat the autopilot kicks in if the hydrovane gets it wrong (perhaps being knocked too far off course by a bigger wave to recover). Only this time we have the autopilot steering to the wind vane at the top of the mast. So once we set the angle of the wind to the boat that we want, the autopilot, like the hydrovane, aims to keep that angle. It means we don't have the autopilot and hydrovane fighting each other if the wind direction changes, but it does mean that if the wind does change direction the boat course will change. Generally with the wind swinging back and forth between SSE and SE, that's not a problem; the track of where we've been just looks like we've had one too many as it snakes back and forth! The autopilot does beep to warn us when there's been a wind shift, so we do know what's going on and can react if the shift is too great and we go right off course.
When in Cape Town we downloaded a number of podcasts from the BBC. It's the first time we've done that and listening to Desert Islands Discs in the middle of the ocean makes a nice change on night watches!
