I think the cautionary tale here should be:
1) Do not run at excessive speed through an established anchorage.
2) Speed should not exceed visibility or conditions.
It doesn't sound like they were running radar
or they weren't paying attention to it. This also would have dictated lower running speeds since they are now relying purely on visual navigation
It sounds like a boater who was operating recklessly. They were travelling through an anchorage at higher rate of speed than the conditions dictated. They were not paying attention to their surroundings. In this case it sounds like the powerboater is assuming all anchor
lights are at eye level and never bothered to look up to see the anchor light on the top of a mast
(higher than one would typically be on a powerboat).
As a result we have loss of life. I don't see how having an anchor light would have resolved this. Very sad and my sympathies to the families who lost
loved ones. In particular, my sympathies to the family
of the loved one who placed his trust in the skipper
at the helm
who caused this incident.
