Review of World Navigator deck 8 (Helideck)
Observation Deck is generally open for wildlife viewing and just enjoying the ocean view. It is also the ship's largest open space accessible at any time (subject to weather /sea conditions). Observation Deck is surrounded (fully encircled) by a jogging / walking track.
The aft-located Helideck has a dedicated helipad (helicopter-landing area) used in cases of emergencies.
