Folding space you wouldn't have to worry about it. Two dots on a paper, fold paper. No problem.
Now, for a weapon, take that hyperluminal field bubble and brush it up against a, relatively, at rest mass. The boundry layer forces would rip it to shreds.
Again, take the field and use it to concentrate "gravity" into a packet. Enough gravity to create a microscopic black hole effect. Temporarily of course, but anything hitting the Schwartzchild would fare no better than the au natural phenomena.
Back to folding space. Use the co-ordinates of your targets mass as a "transfer from" point. Rip vital pieces of their ship/planet right out from under them.
Even assuming a 4D field is required, along with attended "hop" limitations, use a series of "motors". Plan your hops two or three ahead and feed them one on top of the other into your motors sequentially. Taking 1 millisecond hop to go 250L would put you in another galaxy before lunch.
my system neither folds space nor uses reaction mass. displacement is caused by a "vector" chord through the subsidereum defined by the shape and strength of the lobes of the field
a prudent captain would run redundant diagnostics to make sure nothing important went queer during the first hop...
not a "4D field" but a four-lobed field. think "shaped like a fat caltrop" and you get the general idea.
weapon: lengthen the field through the target and displace a large chunk, even just a short distance: exposing the innards to hard vacuum and severing many ship systems.
not so dramatic as a move-through brush pass, but more precise.
