The warship's captain seems to be rather annoyed by the dodging of the ramming, but still takes the opportunity to unload as many siege weapons as possible, while maneuvering to grapple with Martel's ship. The ship might be damaged, but its crew is well trained in using the various cannon, and clearly intends to soften up his ships, before engaging. It doesn't help they're likely irritated about losing the prize ship, either.
