Under International Association of Antarctica Tour Operators (IAATO) regulations, no more than 100 passengers may set foot at any single Antarctic landing site at the same time. Aboard vessels carrying 100 guests or fewer, every passenger disembarks together — eliminating half-day onboard rotation waits and doubling unhurried hours at penguin rookeries, historic huts, and narrow channels.

Small-ship polar vessels range from 12-to-76-guest micro-expedition ships (such as Secret Atlas and Antarctica21’s Magellan Explorer) up to 95-to-100-guest expedition classics operated by Oceanwide, Polar Latitudes, and Poseiden, offering nimble Zodiac turnarounds when spontaneous humpback or orca encounters appear.

Small-Ship Antarctica Cruises (≤100 Guests) — Frequently Asked Questions

Why does the 100-passenger limit matter in Antarctica?

IAATO strictly caps shore landings at 100 passengers ashore simultaneously per site. On a ship with ≤100 guests, everyone lands at once for the full window; on a 200-guest ship, passengers split into two alternating groups.

Are small expedition ships safe in the Drake Passage?

Modern ≤100-guest Antarctic ships hold Lloyd’s or Polar Code ice ratings (such as 1A, 1B, or PC6) and active fin stabilizers, and several small vessels also operate fly-cruise itineraries that bypass the Drake Passage altogether.

Do small ships visit more landing sites than larger cruise ships?

Yes — ships under 100 guests qualify for restricted IAATO Category 1 sites with lower daily visitor caps and complete full-ship Zodiac embarkation in under 20 minutes, frequently achieving two full landings or Zodiac excursions per day.
