    Possible southern reef closure

    No kidding, they learn quick. Most hard coral will shred you quicker than a vega-matic! :eek:

    Possible southern reef closure

    So they are basically keeping all people out of the least affected areas to see the effect. Most likely the disease will spread unabated, the onus be lifted from divers and the areas reopened to bear witness to the sad demise. I feel fortunate to have experienced Cozumel diving before this...

    Fire on dive boat Conception in CA

    Please pardon me if this has already been suggested. I web-searched "camera based fire detection" and a plethora of existing offerings came up. These systems are designed to monitor entire rooms and provide earlier warnings than other systems. An IR system could detect a failing battery or...

    On further thought, the ejection idea wouldn't be so good if you were moored next to another boat :( o_O

    Not as simple, but very doable: Base operation on a motion detector.

    Fire on dive boat Conception in CA

    The USCG recommendation of "consider limiting the unsupervised charging of lithium-ion batteries and extensive use of power strips and extension cords" would mean not everyone could charge when they might wish. That could be difficult to manage. Also, what would be an effective method of fire...

    True, but it would provide some assurance it was being monitored and allow for flexibility in the hours of operation. As Wookie earlier commented, problems were preceded by unusual heat and odor, everyone could be instructed to check for this.

    Yes, but every one I've seen still takes minutes, and I think you could get at least most out of that bunk room if detected early. But certainly not out that little escape hatch. Not having a smoke detector in the compartment above the sleeping quarters is just a head-shaker for me.

    And ironically two of the least desirable bunks on the Vision may become the most coveted, those directly under the escape hatch. No one was sleeping in those bunks on my trip, though admittedly I was close and had it scoped. I saw a pic of one these bunks where it was not surprisingly being...

    Fire on dive boat Conception in CA

    You don't expect a fire to become involved so quickly as to block a primary exit unless there is an accelerant involved. This is why suppression systems focus on locations like the engine room. Seems batteries are being identified as an accelerant and may warrant the same consideration.

    The charging station could be on a timer that had to be reset every say 30 minutes. If no one was around to perform a reset, it would turn itself off.

    Fire on dive boat Conception in CA

    So the smoke alarms go off, it's dark, and everyone being suddenly awoken are disoriented. Makes me think of the directional indicators on the floor of airliners that direct you to the emergency exit. Seems something like this would be a good thing. Isn't the emergency hatch is really meant...

    A sprinkler system might save the boat, but not the occupants of the room. They would succumb to smoke inhalation before the fire got hot enough to set off the sprinklers. It's about early detection and egress.

    Fire on dive boat Conception in CA

    I'm thinking if a one in a pile of batteries ignited, starting a chain reaction, it could get ugly real quick. Such that unless the watchman was nearby, it may not of made a difference. But then at least there would be a chance, seems there was none under the circumstances. That door was the...

    Yes, a bit, next to the exit.

    Fire on dive boat Conception in CA

    Not sure what you mean, but I'm pretty sure there was only bunks for five in the crew quarters. The sixth crew member was an office worker who had begged to go out on the boat, so an extra. We also had an extra on our trip, also an office worker they had wanted to experience the boat. She...

    The charging station was located at the starboard aft end of the salon.

    Fire on dive boat Conception in CA

    There was mention earlier in this thread about a GPS based alarm that acted as an anchor watch. They had alerted the crew about the boat drifting, and was told the alarm hadn't been enabled. I thought they said it was on this boat.

    I had earlier posted a picture of the Vision showing the stairs down to the deck, but I’ve since seen a picture of the Conception and it is a bit different. The stairs angle such that the top entry is directly above the salon exit so about any amount of smoke/heat pouring out would block the...

    I must apologize, I was too quick to click. I shouldn't have implied it as a viable option. But on a perfect summer night it would be way cool. I so hope they they come back..
