These aren't "island-ish" seeds: for each one, the spawn point sits on land with ocean covering at least 80% of everything within 400 blocks. The percentage on each card is measured, so you know exactly how isolated the start is.
Island starts flip the early game — wood is scarce, food comes from fishing and kelp, and every expansion begins with a boat. Check the map thumbnail for nearby shipwrecks and ocean monuments before picking your seed.
