Log
- Very very severe gale. This is developing into a bad gale. Winds over 50 knots.
- Most terrible squall for the whole voyage went through. Goodness knows what the strength was as anemometer only goes to 50 knots. It would have been 60+ knots. Big seas and a bad one.
- Got a bit of  broken glass on my foot extracted with tweezers.
