Today Tuesday 24th BlackRob's schedule predicted St Kitts but it is something like 09:50 UTC (if it is the same as GMT so UK time less an hour?) and she is still at the Cruise parking in Bridgetown (Barbados). So perhaps the hypothetical privileged whale has found some other way of getting home. It would be interesting to reconstruct the previous week or two to see when she went back to St Kitts since presumably most of the IAS came that way but that was the week when the vessel tracking site did not give standard information: radar switched off again? Too much of a coincidence to be accidental?
