Very sad story. He is in hospital with internal organ damage, and his wife is dying of cancer and navigates from a wheelchair. Another couple might recover from this, but this elderly couple… not easy.
With regard to what they hit… maybe rocks, but there are plenty of uncharted wrecks in that area as well as all over SE Asia
. Heck, a friend of mine hauled up a longtail with their anchor windlass
earlier this year… But uncharted rocks? Frankly it is the norm in SE Asia
are poorly if ever updated and original data often sketchy. I have at least six chartplotter images
of me anchored high up a hill… Pan Asia/Pacific problem. Caveat navigator. Particularly in shallow waters such as Phang Nga/Krabi. As I said. Very sad.
