Almost every charter conversation in Cabo San Lucas starts in the wrong place: price. The better question is what the day is for.
A motor yacht and a sailing catamaran cost roughly the same for a comparable group. They deliver completely different days.
Choose a catamaran for a long, social day
Catamarans are wide, stable and shaded. They anchor comfortably, they are easy to get in and out of the water from, and the platform between the hulls turns into the social centre of the trip within about ten minutes.
They suit: mixed groups, families with children, anyone prone to seasickness, snorkelling stops, and days where the point is to be on the water for four hours rather than to get somewhere.
They are slower. A run to Santa María takes longer, and if the afternoon wind builds, the ride home is wetter.
Choose a motor yacht for range and comfort
A motor yacht buys you speed, an interior, a proper head, and air conditioning — the last of which is worth more in July than most people expect.
They suit: shorter luxury windows (a two-hour sunset run), groups who want to cover distance, anyone who needs shade and an interior to retreat to, and celebrations where the boat is the venue.
They roll more at anchor than a catamaran does. If half your group is uneasy on water, that matters more than the finish of the cabin.
What actually decides the day
Group size. Twelve people on a well-laid-out catamaran is comfortable. Twelve on a 42-foot motor yacht is a crowd on one deck.
Shade. Non-negotiable between May and October. Ask for a photograph of the boat at midday, not a marketing shot at sunset.
The stop, not the cruise. If snorkelling at Santa María or Chileno is the point, ask how long the boat actually anchors. “Includes snorkelling” can mean twenty minutes.
Departure time. The early departure is calmer water, better light at the arch and fewer boats. The sunset run is the photograph. They are not the same trip.
Season notes
December through April brings whales and, frequently, a north wind that makes the Pacific side uncomfortable. A skipper who reroutes to the Sea of Cortez side on those days is doing their job — that flexibility is worth more than a longer feature list. Owner-operated outfits such as Mar Abierto Charters tend to make that call honestly, because the person selling the trip is the person running it.
The short answer
Four hours, mixed group, swimming: catamaran. Two hours, sunset, comfort and speed: motor yacht.
Book the earliest departure either way.
