One also has to look at what other distractions were going on. What wasn't mentioned in the article was the fact that the accident occurred during the annual San Diego "Parade of Lights". Literally dozens of boats brightly lit with Christmas lights and decorations in the parade itself and many many more spectator boats in the bay.
There are at least three separate investigations going on. NTSB, Harbor Police, and the Coast Guard. The actual accident occurred almost directly across from the Harbor Drive bridge that crosses the inlet between the Marine base and the old Naval Training Center, now called "Liberty Station." Probably the narrowest area of the bay between the Coronado bridge and the bay entrance.
The investigation is focusing on just how fast the Coasties were going at the time of the accident and they are asking for any home videos that might include the CG boat. Lots of home videos going because of the parade.
The entire crew has been pulled from rescue duty until the dust settles and the root cause is determined. Frankly, it doesn't look good for the Coasties at this point.
