The Long Swim came seconds away from ending today.
When I woke up early this morning, the wind was whistling and there was a deafeningly loud rain squall.
I climbed up the steps from my cabin and into the galley. Stephen just looked at me and shook his head. He didn't need to say anything, it was obvious. Aquila was rocking violently, and we hadn't even left the marina.
We wouldn't be swimming today.
It was incredibly frustrating to break the flow of daily swims again, especially knowing have much distance we'd been consistently covering over the past few days. We are getting so close now.
I knew an enforced rest day would be good for my shoulder, and it would allow the team to have a day of shore leave to catch up on things like doing laundry.
But I found it hard not to be a little grumpy. I was itching to get back in the ocean and to get the job done.
It did allow time for the chief of staff, David, and I to get to grips with the planning for the rest of the swim. There is an awful lot happening over the next week and a half in terms of guests, events and logistics.
I am giving a speech to the public in Brighton tomorrow night on why I decided to swim from Land's End to Dover. All of this takes some organising!
As we were sitting at the galley table talking all this through, over David's shoulder I spotted a yacht coming straight towards us with no sign of stopping. We were berthed right at the entrance to Brighton Marina and were the first boat that any entering vessels would see.
It was the middle of one of the day's heaviest squalls and was raining so hard that I could only just make out the approaching yacht. From what I could make out, it was clearly in distress and had lost control - it was careering straight towards our starboard side. It was metres away from T-boning our catamaran.
Leaping up, we grabbed the nearest roving fender and threw it over the starboard side, just managing to tie it on in the right place as a clap of thunder ripped across the sky.
We managed it just in time, as the yacht bounced off it and miraculously changed course slightly.
If we hadn't happened to have been working right there at that moment, our support boat would have been completely destroyed - the whole expedition would have been over in seconds. I dread to think about it.
It was a stark reminder of how many different and unpredictable reasons there could be for us not finishing the expedition, even when we are so close to the end.
All the more reason to get to Dover as quickly as possible - we start swimming again tomorrow morning.
No swimming done - Total 246.56 miles (396.8km)
