 The result was the Vagabond, essentially a side-by-side version of the tandem J-3 Cub credited with saving the company.The PA-16 Clipper is a stretched and refined version of the Vagabond intended to seat four people (or "two-and-a-half to three" as often told by Clipper pilots).It is equipped with an extra wing tank, added doors to accommodate the new seating, and a Lycoming O-235, the same engine that would later power the Cessna 152.
