Back in the day I used to crew some on a R-24. I also raced and cruised a Ranger 20 for 5 delightful years.
The R-24 fleet and the SJ-24 fleets used to race same courses, each for their own one design trophies. Both were designed to the old quarter ton IOR and both were about the same average speed around the buoys. The Rangers were noticeably more stable with the chute up, tho. (The Kirby-designed SJ had quite a reputation for washing off spreader tips on a windy run with a chute up!)
For general cruising, the Ray Richards Rangers had an excellent interior design, with head aft. Matter of fact, C&C used/copied that interior for one their C&C 24 variants.
Ray Richards designed both his Ranger 20 and 24 for easy and efficient sailing with their cockpit layouts, and with useable interiors that could cruise with a couple easily. Both were unusual for having positive floatation. While having enough foam blocks under parts of the interior did reduce storage somewhat, it's a nice safety feature -- this came about because the owner of Ranger Boats had a concern about boats sinking and wanted the larger line of sailboats to be as unsinkable as their older line of sailing dinghies.
Note also that the R-24, with its motor well, has massive cockpit drainage for going offshore. Along with a bridge deck, it's a very safe boat. Unusual then (or now) the Rangers were build with spendy take-apart molds for the cockpit and interior. That's how they are able to have the face of the seats slope back to give foot room.
The "off shore ancestor" of the R-24 was likely Ray's Haida design. Still popular as a budget ocean boat.
ps: trivia -- Ranger Boats of Kent, WA, is a much older company than "Ranger Yachts" in California... which was illustrated by a very
humorous legal challenge in 1980.....
