Norwegian Prima deck 20 plan (Speedway3-Waterslide)

Deck 20 is accessed only via outdoor stairs and here is The Wave waterslide's entrance level.

Midship is positioned "Prima Speedway" (upper level 3 of 3) with the Speedway Viewing Area. Prima Speedway is NCL fleet's largest racetrack on 3 levels/decks (the old racetracks are 2-level), with a longer straightaway/straight section, 14 turns and total length 420 m (1378 ft), which is ~1/5th larger than the racetrack on Norwegian Encore (fleet's previous largest). The racetrack goes around and through the funnel/smokestack, has max capacity 15 cars (racing simultaneously) and allows max speeds 50+ kph (30+ mph). This unique sports facility is served by the Prima Speedway Bar (located beneath the racetrack on Deck 18).

Midship are the liner's funnels (smokestacks).
