Travelmarvel Sapphire deck 4 plan (Sundeck-Bridge)

The Sundeck has a fore-located shaded seating area (Lower Sun Deck covered by two hard roofs, 4-seat tables), a midship sunbathing area (with deckchairs and sun loungers), and SkyLight (glass roof over the Atrium).

The aft-located Navigation Bridge (called "Wheelhouse" on riverboats) is not passenger-accessible.

All structures on Sun Deck (Wheelhouse, awnings, roofs, windscreens, railings) are retractable and lowered when the ship passes under low bridges. All decks are interconnected via stairs (forward, midship and aft).
