Collective positive thoughts needed right now please...

After being in the water for over 7 hours John is struggling, in the last half hour he only made 300m due to a very strong northbound current that is pushing him way off course and will make the swim much longer if he is able to continue. The water temp is only 15 degrees, not 16-17 as expected and Al has had to stop swimming as he was on the verge of hypothermia. The boat guys are continuing to encourage John to continue and will check his progress on the chart next break to ensure he's not actually going backwards. Damn Cook Strait currents...
