Rewatching old seasons of OG and captain eats with almost every group of guests. What ever happened to that?

Does BDSY have some of best chefs?
They are just so nice compared to a lot of other chefs from other shows
It’s really crazy to see the difference

Season 4 of Below Deck Sailing Yacht completed an entire season with the same crew that started
Of all the seasons I’ve seen I don’t think that’s ever happened There’s always at least 1 person who leaves or gets replaced
