HELP actually worked !

This is the way to do it, make your whereabouts known, sit tight and get rescued.

This is the wrong way: don't listen to the Professor, build a raft, get attacked by sharks, return to same island

Of course getting rescued within a week would have resulted in only 1 TV episode not the 98 over the three seasons of Gilligan's Island :)

Betcha some billionaire is wondering who owns that atoll and whether they could buy it !
