Judging from what was written on #1 and the title of the this thread, I really doubt it has ever been discussed at all.I think they did discuss it first. It would be interesting to hear what was said in that discussion.
If the DM candidate goes on to become a DM on a boat that uses a drop tank, it will likely be his job to drop it, as assigned by the captain. That is why it is a training requirement.
Why would the OP let the boat captain to do his supposed duty?
Anyway the OP has left the resort so.
