Tragic. Several issues that led up to the event. Least of which was vessel was not properly registered nor compliant to Small Commercial Vessel Program rules. For starters if he had the mandatory high water alarm installed there would have been early warning of trouble. Secondly the electrical system did not have a proper house batter and separate start batteries. That way even if the house was drawn down due to high load created by electronic equip, you could always start the mains and power up the system. As always, most of these crashes or sinkings start from a series of small un-noticed errors and are compounded as time goes by.
A good reminder if hiring a guide to ask if the captain and vessel have all their TC safety training and inspections complete.
