Below are a few common events when sailing and what they look like in See Sailing...
This peninsula (Point Jerningham) casts a savage wind hole in the Southerly. You can see the red blotches in our stripe as we reach towards the mark, but also that as soon as we clear it, the boat picks up again nicely.
While beating to windward the helmsman fell out of the groove. You can see from the trail that the mast popped upright and the boat slowed down. A little bear off and everything came back together again.
A strangely consequence free wind shadow leads us into a panic tack from which we never really recover. The boat stays upright and doesn't manage to get back to speed until just before the second tack back onto port. Thankfully the second one is much better and the boat gets back to speed quickly.
At the start of the run a larger yacht flying her spinnaker passes astern. The wind is battered and our windex spins round. Normality is restored when she passes to one side. Oddly this doesn't appear to affect our speed although by looking at the numbers you can tell we accelerated once it passed.
