Alcohol is never sold on a yacht here. On the Azimut 70 and the McKinna 70 the drinks are complimentary and the crew serves them; nobody will hand you a bar tab, and there is no package or price per drink to buy. On every other yacht, guests 18 and over bring their own and the cooler with ice is already on board.
The McKinna 70 is the only yacht with a chef included: welcome snacks and fresh guacamole, then a multi-course menu cooked on board, served by the crew. The Azimut 70 brings a set menu (fish ceviche, sashimi, beef or chicken fajitas, guacamole with chips) with complimentary beer and cocktails, water, sodas and ice; a chef on board is available for an extra charge.
The Sea Ray 65 sells both ways: boat only, or all-inclusive with ceviche, sashimi, guacamole, nachos, sodas and bottled water. It is the one to compare against bringing your own: four hours boat-only cost $2,999 USD (MXN 56,999), and adding the Mexican feast for 14 to 16 people from the menu in the planner (MXN 4,550, about USD 239, cash price) still lands under the $4,659 USD (MXN 88,599) all-inclusive rate, which also covers the sodas, the water and the service on board.
