      Speed, boats need to be outside the area where they might get hit, which is actually quite large.

      Boats, even fast ones, are quite slow. And the larger boats that the fast ones would be deployed from are even slower. So even though that risk area gets smaller as the capsule descends, the big boats are waaaayy slower and still stuck far away. Generally, too far for ‘fast’ boats to get there quickly enough.

      Helicopters are much faster, also relative to the size to be able to have medical staff on hand. So they can get there fast enough.

      There is significant possibility of injury, and often times there are communication blackouts when they would already need to be leaving to make it in time. So, you send the fast thing.
