As the committee member rightly points out, ships can be and often are at sea for long periods. In cases where ships at sea might be transiting long distances, we have the ability to get ballots out to the ships in advance when they're within range of certain areas. Although a ship might be at sea for 35 days, it wouldn't necessarily be so far away from the nearest port that we wouldn't be able to put a helicopter ashore and arrange for a pickup of ballots to bring them back. There is also the potential to utilize other navies to help with transport.
I know of no situation where we've done that before, but the potential is there. Ships, even though they're at sea for 35 days and can stay at sea for longer than 35 days, have the ability to get within transportation distance to transport ballots as need be.
