If you listed such boats, one would of course have to see whether or not such boats were in fact available there, where they were berthed or stationed, at what state of readiness they stood, etc. One would then have to look at whether or not such boats could stop such a ferry under the listed conditions and within that short a timeframe. But it seems to me such will not be necessary. You've pretty well shown that you're grasping at straws, though for what reason I'll be polite enough not to say.
As for others with direct knowledge, they're certainly welcome to chime in at anytime - fr is quite open. But I'm sure that we'ed both expect any such sharing of expertise to be circumspect as to what is said in so public a forum.
