No, even if you extend the towed array to its maximum length, a speed of 7 knots is sufficient to have the towed array in line with ownship.
No problem of having it drag over the ocean floor.
Go less than 7 knots and yes in shallow waters you'll find the towed array being dragged all over the place.
And frankly the tactical speeds of the 688/seawolf/virginia are quite high that going at 7 knots is no problem at all to search for enemy subs.
