Looking out to Cornwall from the Royal William Yard last night we could see the tides and currents that give Devils Point its name. 7 currents converge here.They are really easy to see with the naked eye. All but invisible with a simple phone camera, but by just adding a bit of extra colour I can show the complexity of these waters.

Sir Francis Drake made Devils Point famous by making a pact with the witches and demons of the area to create a storm that would incapacitate the Spanish Armada. Other versions are available.

There must be something about the waters around here. I tend to take my demons with me when I swim nearby and then cast them off as I enter the chilly waters. It works every time.

What3words even allows me a small mantra to call up my own wizard for dealing with rivals/demons at my most regular swimming spot.

Something rather devilish about these parts
