The decision was made not to restart (Pip says so in her recent update): it seems the depression will take longer to blow through than initially expected and the implications of having all the boats milling around, presumably in a relatively small area of very rough seas and with insufficient safe havens, for an extended period sunk in.
For those criticising the shortening, I think it's worth bearing in mind that this is a preparatory event to build qualifying miles for the Globe itself, breaking boats (let alone losing them or even skippers) would be counterproductive. The skippers are racing for fun in a class that's run by the sailors. Yes, they have to meet sponsors demands but those sponsors will have to foot the bill for any repairs or rebuilds.
I think pretty much everyone involved will be disappointed but that doesn't mean it was the wrong call. ISTM a very different situation from a following storm in the south during the Main Event.
Great to see, Conrad is enjoying a joke on the reach home.
