Only on cabin bookings. Classic and Premium Catamaran cabins include a Host and half-board, meaning six breakfasts, six lunches and two dinners cooked on board. Full yacht bookings don't include food; you can add a Host, but the Host's fee doesn't cover the food, and you'll provision the yacht near the marina on the first day.
For how food, drinks and provisioning work on each type of booking, see Is food and drink included?
