Pez Gato / Tropicat Jazz and Sunset Cruise
For a $200 budget, I'd think small-group sunset sail rather than private. Private boats in Cabo get expensive fast once you add crew, fuel, dock fees, etc.
A 2.5-3 hour sunset sail out of the Cabo marina, visiting the Arch/Land's End, with a slow cruise on the Pacific side if conditions are good, drinks/snacks included, and not one of the loud party catamarans, is the perfect fit for a relaxing and enjoyable experience.
