Once my sea sickness had disappeared, I found sleeping on a fishing boat to be very comfortable. A little bit too comfortable, in fact…

09:00 – The battery on my phone died – It’s taken me nearly half an hour to figure out whether it’s Monday, or still Tuesday…
I’m not sure if it’s an advantage or a disadvantage, I suppose it depends on how you look at it? But sleeping on this boat has its issues. When I’m at home, I usually only ever go to bed when I’m tired and I rarely lie-in – once I’m awake, I’m awake, and I get out of bed, even if it’s just to sit and watch the news (Jeremy Kyle)
