> just leave for a weekend every 90 days and start the clock over. Regularly leaving an island ~500km away from the nearest city (where you might go through immigration and get your passport stamped or however they check this) is more involved than the usual "just do a day trip to the neighbors" situation. Not impossible but a cost to factor in. In my quest to not fly whenever reasonably possible, I looked at ferry options to Iceland and I don't remember the results but the short of it is that we flew.
