The hull of the MARINER is the same as that of the RHODES 19. A fixed keel version was also available for both boats. In 1969, a '2+2' version was introduced that has a slightly larger cuddy/cabin. A modified version (with different cabin design) called the SPRINDRIFT ONE appeared in 1980 after the original molds were sold to Rebel Industries-(Spindrift One-Designs).(76 built). Since 1986, the licensed builder has been Stuart Marine Corp. of Rockland, ME (USA).(Also builder of the RHODES 19).
