The Nacra 5.2 is an American catamaran sailing dinghy that was designed by Tom Roland as a one-design racer and first built in 1975. Other than the small production run Nacra 36, the Nacra 5.2 was the first Nacra brand boat and established its reputation.{{cite web|url= https://sailboatdata.com/sailboat/nacra-52|title= Nacra 5.2 sailboat |access-date= 2 August 2020|last= McArthur| first= Bruce |work= sailboatdata.com|year= 2020|archive-url= https://archive.today/20200802172700/https://sailboatdata.com/sailboat/nacra-52|archive-date= 2 August 2020 |url-status= live}}{{cite web|url= https://sailboatdata.com/designer/roland-tom|title= Tom Roland|access-date= 2 August 2020|last= McArthur| first= Bruce |work= sailboatdata.com|year= 2020|archive-url= https://archive.today/20200802173447/https://sailboatdata.com/designer/roland-tom|archive-date= 2 August 2020|url-status= live}}Sherwood, Richard M.: A Field Guide to Sailboats of North America, Second Edition, pages 84-85.

Design
The Nacra 5.2 is a recreational sailboat, built predominantly of fiberglass. It has a fractional sloop rig with a rotating mast, anodized aluminum spars and nine full mainsail sail battens. The symmetrical hulls have plumb stems, reverse transoms, transom-hung fiberglass rudders controlled by a tiller and retractable fiberglass daggerboards. The boat displaces {{convert|350|lb|kg|0|abbr=on}}.
The boat has a draft of {{convert|2.50|ft|m|abbr=on}} with the dual daggerboards extended and {{convert|6|in|cm|abbr=on}} with them retracted, allowing beaching or ground transportation on a trailer.
For sailing the design is equipped with trapezes to allow the crew to balance the boat. The design includes on-water adjustment controls for the shroud tensions, outhaul, jib luff and mainsail downhaul.
The design has a Portsmouth Yardstick racing average handicap of 72.0 and is normally raced with a crew of two sailors.
