With heavy seas and a broken alternator belt, John and Fionn start to doubt if they'll ever reach La Rochelle

It’s not all plain sailing (sorry) as our cruising companions press on down the French Biscay coast. Off the coast of Les Sables d’Olonne an alternator belt goes and Fionn is forced to make a repair in rolling seas.

Will this cost them time or will they reach the confines of La Rochelle harbour on schedule?
