I was thinking of my own dinghy arrangement, which is upside down over the hatch, which opens 18" or so into the body of the dinghy. You couldn't get out directly with the dinghy lashed down, but you could easily reach around the hatch lid to slash through the PVC bottom of the dinghy and then the hatch would open all the way. But of course not everybody's stowage is the same as mine, so I accept it's not a generally applicable solution.

    Yes, its a distinct possibility for some arrangements. I'll have to investigate mine to see if the knife/hatch idea is ok.

    I'd like an rapid self-inflating dinghy as with mine on the foredeck its v. difficult to get safely to the anchor, furling drum etc.in a hurry.
    I assume there isn't such a thing (without a large enough on-board supply of compressed air cylinders)?

    A good point, though.

    Got to be able to open the hatch first, to access any lashings from below.
    If dinghy is lashed down securely, it would be impossible.

    See #18. It appears that it floated for a while after the fire was extinguished then (in some order) capsized and sank.

    This USCG link includes a chilling vid depicting the intensity of the fire which burnt the vessel down to the waterline before it sank.

    The inquiry will make sober reading.

    I've rummaged out a snapshackle which will be used to secure the dinghy transom to the babystay fitting.
    Should be releasable from below, by opening the hatch a few inches.

    I once had the dinghy on the foredeck and couldn't easily get out from below to talk to someone, as I had the companionway apart to get at the engine.

    Yeah, agree. Too early to say for sure but seems it could well be the fumes that got people very quickly. Surprising how few people take that into account in tragic fires. If you have to mess about even briefly to cut your way through a dinghy, it may well be too late.

    I think you'd need to be looking at high-volume electric pumps. There are plenty of moderately-priced ones which are effective enough to be useful, but for truly "rapid" inflation I think you'd be needing something quite high-end. The Scoprega Turbo-Max does 1000 litres per minute at dinghy pressures (be aware that a lot of pumps now are aimed at paddleboards, which have a different pressure/volume tradeoff), albeit it sucks current like an anchor windlass while doing it
