Tips for the swamp

Hi, new player attempting first run. Just moved on to the swamps, since i believe they are the next biome after the black forest. Im having trouble surviving the swamp and have noticed that the set of bronze armour i have, had met a wraith while sailing and it destroyed my boat and then killed me, is not that great even against basic draugr. Is it even worth me getting a new set of bronze armour?(I dont think i feel like going out to the middle of the sea by wraith to get my stuff back) Or i just get better at parrying and go naked with a shield and weapon? Also is the bone shield better than the bronze bluckle?
