The original Centuri Marauder was released in the 1969 Centuri catalog. It was advertised as an ideal beginner multi-stage rocket using Centuri's "dual-lock" stage coupling, later known as the Pass-Port Staging System. It only had a three year production run, but is still remembered by many as their first two-stage rocket. It was re-leased as #KC-45 and retailed for $2.75.
The Semroc Retro-Repro™ Centuri Marauder™ is very close to the original. The pre-printed fins are replaced with more convenient laser-cut fins. The original balsa nose cone is supplied instead of the later plastic nose cone. The original rubber shock cord is replaced with an elastic cord for longer life along with a Kevlar® cord for greater reliability and ease of mounting.
