This begs the question -- did the minesweeper have a depth sounder (I assume it did), was it in operation at the time of the grounding, and would it have provided a warning of the reef ahead?
Also, the latest depthsounders in the recreational market are "forward looking" and can provide warning of obstacles ahead. I therefore assume the Navy has had them for years. Was the Guardian equipped with such a sounder and was it in use?
It will be interesting to see the full report from the Board of Inquiry.
