Beautiful video! I always enjoy your footage.
I agree, bad things can happen at any time, and that applies to anything in life. I place a high standard for liveaboards when it comes to maintenance and safety, more than other types of vacation experiences. IMHO, besides weather, most instances of a liveaboard to cease operation before and during a trip are avoidable and human driven. Proper and regular maintenance checks will keep the boat in tiptop shape. These liveaboard companies are insistent to turn the boat for the next trip, and I wonder how they can do any bow-to-stern inspections in the short time the boat is back at the dock. Well, they really can't, because greed drives the schedule.
An experienced captain who is well familiarized with the waters in which he/she is sailing should not hit obstacles in the ocean. My only experience on a boat is as a passenger, but it seems like GPS, gauges, nautical plotting maps, and advanced technology should keep any boat from impacting any fixed object in the water.
