The Seahorse was carrier capable. High stall speed made it impracticable.
Worth reading about.
Just been reading, seems there were a few modified for navy testing, but too many modifications took away the advantages. Also the airframe was not strong enough for long term carrier use. I did find out they were able to easily take off from carrier decks, and most were transported on carriers to their overseas bases, and then flew from the carrier to their fields.
