Two TA = No bearing ambiguity

It won't. That's just roughly equivalent to a towed array with a longer set of hydrophones than normal. Bearing accuracy might go up if they are integrated correctly, but there will still be two solutions for the same time-differences.

As for offset, we are talking maybe 10 lousy meters (width of sub), and unlike the fixed bow arrays, the relative positions of the two are not precisely defined (they float around in the water).
