It is actually this one but with a specially made bag to store it in the anchor locker by Ribcraft and the small straps replaced by permanently attached webbing / snap clips in 316 stainless also by Ribcraft
The RC straps attach to the inboard A frame ground eyebolt and topmost A frame transom eyebolt
Not to dissimilar though - at least both these versions are 316 stainless; the Armstrong is only 304
