Probably wouldn't have been able to anyway, since it's unlikely a passenger liner would have the capability to outrun most, if not all, warships smaller than a battleship or dreadnaught.
SWM wrote:That is correct; Artemis was only damaged and could not get away without repairs. But you are wrong when you say that the Wayfarer was in normal space after it was crippled. It was not; the text is very clear. It was still in the Delta Band, and would be destroyed whenever the rogue grav wave came along. Contrary to your thesis, there are no grav waves in normal space.
Replying to SWM in reference to the last line (my bolding):
There is one
known, limited (and a second
possible, slightly more general) exception(s) to that statement.
First the known exception: Wormhole termini have a gravity wave "current" (ripple or eddy) flowing out from the terminus.
This is (one of the reasons) why we see ships in the departure lanes rigging the fore Warshawski sail while still under impeller drive (wedge at half of its strength generated by both sets of impeller rings) prior to transit. Initially the foresail picks up the gravity wave extending from the terminus (into normal space) and once the ship is deep enough into the wave--the point where the foresail is drawing enough power from the wave to provide movement--the ship shuts down its wedge completely and rigs the aft sail.
The ship then is driven forward under the impetus from the gravity wave to the Warshawski sails alone. Once it is deep enough into the terminus, it then makes transit (using the hyper generator). Upon completing transit, the ship reverses the process, initially moving out of the terminus (in the gravity wave of the arrival lane) under Warshawski sail, until it moves far enough away that the gravity wave no longer provides impetus to the ship's sails and it is safe to reconfigure the sails to the wedge.*

The grav wave which forms a wormhole is very, very powerful; the grav wave “current” which flows through a wormhole, while still much more powerful than any impeller wedge, is effective an eddy or ripple set up by the “roaring deep” grav wave which formed it in the first place rather than a part of that wave itself. In other words, there is no direct association between the strength of the forming grav-wave and the one a transiting starship must deal with during transit.

The second,
possible exception (which we probably will not see due to it happening (if it happens at all) until 200 story years in the future is found in this (different) part of the same post quoted above by David Weber:

In another 200 years or so, Manticore-B will actually be closer to the Junction than Manticore-A is, at which point things are going to get ugly. Manticore-B will acquire its own (temporary) resonance zone (no one knows at this time how powerful it will be), and the hyper-space conditions in Manticore-A’s resonance zone will be absolutely lethal. Indeed, some hyper physicists are predicting that the zone will be so intense at that time that it will begin affecting normal-space navigation within the zone. By 2120, things will have settled back down into roughly their current state, and 300-400 years after that, the Manticore Binary System will be back to the nice, quiet conditions which obtained when the system was first settled.

Re: SPOILER - finding the torch wormhole's destination.I suspect if the second exception ever happens,
gravity ripples or eddies (as opposed to a gravity wave) might appear in the resonance zones of the Manticoran Wormhole Junction at that time. Probably similar to turbulence encountered by an airliner (which can range from minimal to extremely severe).
