However there will be no respite on board the British Maxi.
Slade set out to make an assault on the race record set by Nomad IV last year and his team will be coaxing every ounce of speed out of their charge.
Leopard 3 is 160 miles nearer the finish than the 'Ghost of Nomad' but 13 hours behind on estimated elapsed time. The next big decision for Leopard 3 will be how to cross the pressure ridge in front of them.
The RORC Transatlantic Trophy will be awarded to the best yacht racing under IRC, after time correction.
Arco Van Nieuwland & Andries Verder's Dutch Marten 72, Aragon continues to impress and is estimated to be still leading after time correction.
Leopard 3's quest for the race record has also put the team up the IRC ranking into second place.
However, the biggest improvement in the overall ranking has come from Infiniti 46 Maverick, skippered by Oliver Cotterell, which is making a move north.
In the Class40 Division, Halvard Mabire & Miranda Merron's Campagne de France has opened up a substantial lead on Catherine Pourre's Eärendil.
Campagne de France is 160 miles further west than Eärendil and should experience fresh winds before their rivals, but should the breeze come from the east, Eärendil may well close the gap.
Lloyd Thornburg's Phaedo3 is approaching the halfway point in the race MOD70, well ahead of their Italian rivals, Maserati, skippered by Giovanni Soldini.
