if you picture it in your mind
a bass feeding in a fast tide will know how fast it has to paddle its tail to maintian a stationary position enabaling it to ambush any passing prey,
during this waiting time for prey to float past it will be looking at everything else and assessing it as it floats by so if something suddenley speeds by it at a much faster rate of knots it only has two options eat or carry on waiting and as it is already using vast ammounts of energy maintaining its strike possition it will probably take the later of the two,
as for the cloudy water problem if the bass is on the sea bed it will not nessercerely be feeding there but using the stired up sand to hide its self from fish/prey floating higher up this makes sense to me as looking up thru the water everything creates a black silouet against the sky (this is why so many lures designed for drift fishing are black) so try bringing your bait off the bottom a few turns when the water is murky it may bring a few more fish to the net
