5 Herself had run into that hazardize;
hazardize > hazard, peril (WU)
6 Whose mariners and merchants, with much toil, 7 Laboured in vain to have recured their prize,
recured > recovered prize > {A ship or property captured at sea; here "captured" by the quicksand}
8 And the rich wares to save from piteous spoil,
spoil > spoliation
9 But neither toil nor travail might her back recoil.
travail > labour, painful labour back recoil > draw back, recover (pleonastic, and thus intensive)

On th'other side they see that perilous Poole,
2 That called was the Whirlepoole of decay,
In which full many had with haplesse doole
4 Beene suncke, of whom no memorie did stay:
Whose circled waters rapt with whirling sway,
6 Like to a restlesse wheele, still running round,
Did couet, as they passed by that way,
8 To draw +their+ boate within the vtmost bound
Of his wide Labyrinth, and then to haue them dround.
