What is different?
Air conditioning. Of the six own boats, only the Mares 50 has it.
Room for service staff. The Premium Open Bar bartender, the DJ and the photographer count toward capacity. The Rio Star 50 takes up to 24 people on board with staff; the Mares 50, up to 23. With 22 guests, the Rio Star 50 has room for two of these professionals (for example, the bartender and the DJ); the Mares 50 has room for one. With 21 guests, both have room for two. The crew can take the place of the All Inclusive Premium grill master and bartender and of the BBQ with Sides grill master, and in that case they don’t take up guest spots.
Finish. According to the boat’s page, the Mares 50 had a complete refit, gained an extended deck with a table and sofa at the stern, and has an indoor lounge with a TV.
Worked example: 22 people on a Saturday, with an open bar
Common inputs: Route 2 (Praia Vermelha), Saturday morning (9am to 2pm), regular price, 22 guests plus the bartender (23 on board), Premium Open Bar.
