Ribcraft 4.8m with Yamaha F60 or Suzuki DF60 (only 110kg) is nice balance. Two person jockey console works well. Few examples on used market just now. 5 year warranty on boat if you buy new. Tubes are hypalon.

Don't think I've seen a second-hand Ribquest 4.8m in 4 years of looking. I visited Ribquest when Dave Rose was running things in Sheffield. Quality boat in Orca fabric. Can take up to 70hp, so new Yamaha F70 would be option, but not cheap.
Searider 4.7m - can't comment. Has loyal following here and justifiably so. Someone will give you low-down on best match engine wise and seating configuration.
Zodiac 9 Man Pro (renamed 500) I wouldn't class as a deep v. Most examples I've seen are matched with a Yamaha F60. Seating wise bench seat and forward bow cushion is for family set up. or 2 man jockey. Comes with 5 year warranty on tubes and hull. Usually PVC (Strongan Duotex fabric) but now available in hypalon/neoprene. Huge dealer network and more accessories than you can shake a stick at. More suited for the South of France in my opinion!
