If he sets off now, he'll be in Jersey (or at least Alderney) for tonight!
I have no clue as to whether his crew is doing the festival thing at the weekend, or if they need to be back in Jer asap. But the wind is currently 15kn SW which will make the cape choppy, mind you after three months apart man and boat may well fancy some leg stretching.
Well he's either sunk, had the boat impounded (after his brush with the Le Harvre police last time) or turned his AIS off 'cos he's not showing in Le Harvre any more nor on the high seas. The weather tomorrow looks better so I suspect that he's staying in Le Harvre tonight to catch the better weather back tomorrow.
