It is dated Jan 6, looks exactly like the boat they were fixing, has the same brand new motor, same picture and letters on the side, and the bottom looks like it is squared down the side indicating what would look like a modified or glass bottom.
The vast majority of boats in Cozumel use the same or similar Yamaha motors... Just like the one in the video, though I wasn't able to tell if it was brand new or otherwise, and I doubt you were able to either. Outside of that, you really can't tell much of anything from that video.. The variety of custom modified pangas in Coz are wide ranging, especially after retrofits and restorations by new owners with specific customizations in mind. I know nothing about the boat that went down.. Just stating what I have seen..
BTW it has nothing to do with quickly convicting anyone, the investigation is obviously confused as to exactly what vessel went down. That not only shows them but gives brief views of the bottom and a brief view of the area where the registration number is. It is very bright with sunlight but I am sure it could be edited to show the numbers.
The (real) "investigation" taking place in Cozumel is likely a whole lot less "confused" as the one being conducted in this thread and possibly elsewhere online. While you, me and the majority of others speculate and pontificate, I'm fairly sure the powers that be on the island are well aware of exactly which boat was registered, which boat is now sunk, and who all is involved, their roles, etc. While this may break a few hearts, I have a gut feeling no Mexican officials will be showing up here (or anywhere else online) to give us their findings.. I'm glad ScubaDoc shared what she did.. I don't expect anything more, nor do I feel entitled to it...
Despite the events that lead to Mau's boat going down and 8 or 9 divers and crew floating for hours, I feel there is good that will come out of this, just as I feel there are positives many took away from Brendan's death late last year, which has opened many eyes to the reality of CO poisoning, and testing for not only 02 but CO to prevent gas related injuries and death. Personally, I won't dive off-shore any longer without carrying a personal locator such as the Nautilus Lifeline, McMurdo Fastfind, SPOT locator, etc, just as I will not breath air from any tank until I test if for both CO & 02 content. They are a small price to pay for your life.. If you can afford a dive trip, you owe it to yourselves to afford these devices first.. OR, you can keep rolling the dice..
Cozumel is an exceptionally safe place to dive, just like the FL keys, Bonaire, Roatan, Fiji and hundreds of other dive destinations, but "at the end of the day", and especially before you splash, every diver is responsible for their own safety... Ask questions and equip yourself accordingly..
