This is one of those harsh realizations you acquire in the game at some point. You realize everything heavy sinks and so from then on out you actively beach and dock your ship in areas you know you'll be able to recover the materials if your ship is destroyed. I remember getting stranded when I first learned this lol. Mistlands makes the fear real again because of the lack of beaches across 90% of the biome. All it takes is sailing into that one interesting looking cove only to find out that it had an infested mine and about 6 seekers flying at your boat to lose everything.
