The Monnett Monerai is a sailplane that was developed in the United States in the late 1970s for homebuilding. It is a conventional pod-and-boom design with a V-tail and a mid-mounted cantilever wing of constant chord.

The kit assembles in approximately 600 hours. It has bonded wing skins and incorporates 90° flaps for glide path control. The pod-and-boom fuselage consists of a welded steel tube truss encased in a fiberglass shell, with an aluminum tube for the tailboom. A spar fitting modification was released in 1983.{{cite magazine|last1=Moll|first1=Nigel|last2=Comstock|first2=Bryan|date=May 1983|title=Monerai Service Bulletin|url=https://books.google.com/books?id=nDrlpoetcl0C&pg=PA12|department=Reporting Points|magazine=Flying|publisher=Ziff Davis|volume=110|issue=5|page=12|issn=0015-4806|access-date=15 August 2016|via=Google Books}}

A powered version was designed as the Monerai P with an engine mounted on a pylon above the wings. A Sachs Rotary Engine was chosen for the prototype.{{cite journal|journal=Sport Aviation|title=Try a new flavor... the Monerai|date=Oct 1977|author=John Monnett}} A version with extended wing tips is also available (Monerai Max) which increases the span to 12 m (39 ft) and raises the glide ratio from 28:1 to more than 30:1.Said, Bob: 1983 Sailplane Directory, Soaring Magazine, page 123.

The powered Monerai P and the unpowered Monerai S versions are identical structurally.
