You don't--and are exceedingly unlikely to hit ANYTHING at that range.
 At least, from what I've seen.  Most of the time RPGs are fired under
100m, or they are used for harassing fire because between the limits
of the shooters and the limits of the weapon, you won't hit any moving
targets.

As a matter of fact, the US Army did a study once that gave it a 51%
chance of hitting a target at 200m that was moving at 9mph in a
straight line.	On a firing range while no one was shooting back and
you could take your time to aim.

Yeah, but the 'up and down' on the firing platform could induce pretty
sizeable errors, while only the cross-winds and relative speeds of the
boats induce a margin of error front and back.

Well, the sail would definitely not detonate the warhead.

Or detonate it.  And I bet the frag off of the OG-7 would penetrate,
never mind the PG-7 warhead.
