We set sail from VaVa’U on October 14^th and have spent the last couple of weeks slowly working our way South, hopping from island to island following the ridge of volcanic activity that spawned some of the Tongan islands many years ago and which continues to spawn new ones to this day. Every now and then a spurt of activity yields a new one. Many break apart and sink (or even float off into the pacific!) but some are more firmly rooted to the seabed and look set to endure for millennia to come.
