AC4: Black Flag - Sinking of the Legendary La Dama Negra

Pretty much did this immediately after my victory over the HMS Prince and failed my first attempt, this being the second one. Almost lost still, only saved by some cautious long distance shots. In retrospect I really should have relied on long shots more. Getting up close was painful and evading her mortar was easy if you pay attention, although ramming was a prudent move due to the focused damage you simply don't get with scattered cannon-fire. Also check out the sheer luck of the waves at roughly 4:21, would have sunk me handily. Worth mentioning this and the previous fight I only had top armour and one of the elite ammunition capacity upgrades, everything else was just shy of Elite. Improved the ship since then and I will upload the last two legendaries when I get around to them.
