In many ways, this is indeed a good news story, but unfortunately it lacks a number of details:
1) Why was their vessel considered not seaworthy? The engine in a sailboat is more for moving around in port than for open ocean sailing.
Apparently they were under sail for a time but they damaged the mast. Makes me wonder though, so much time at sea they couldn't find a way to jury rig any one of their 2-3 sails?
2) Why were they off course? Did they not know how to navigate? Did they rely to much on GPS?
3) There seems to have been a number of planning failures here.
People embarking on things like this really should be required to have insurance of some sort.
