The Mariah SX21 is the smallest boat in our Marbella fleet, but it punches well above its length. At 6.4 metres with a single 180hp outboard, this open bowrider seats up to 5 guests (including skipper) and departs from Puerto Banús. It is not a superyacht – it is a nimble, fast, and honest day-boat for couples or small groups who want to feel the wind and the sea without the formality of a flybridge. This Mariah SX21 Marbella review covers what it is actually like onboard, where it can go, and who it suits best.
First Impressions: Small, Simple, and Fun
Stepping onto the Mariah SX21 at the dock in Puerto Banús, you immediately notice its size. At 6.4 metres, it is compact – no cabin, no head, no shade. The layout is straightforward: a small bow seating area, two bucket seats at the helm, and a rear bench. The upholstery is marine-grade vinyl, clean and practical. The outboard engine sits on the transom, leaving the cockpit open. It is not luxurious, but it feels honest and ready for action. For a Mariah SX21 Marbella review focused on real use, this is a boat that says 'let's go' rather than 'let's lounge'.
On the Water: Speed and Handling
Once clear of the Puerto Banús harbour wall, the skipper opens the throttle. The 180hp outboard lifts the hull onto the plane in seconds. Top speed is around 30–35 knots depending on load and sea state. The steering is direct, the hull responsive. It is not a rough-weather boat – in a chop above 0.5 metres you will feel every wave – but on a calm Mediterranean morning, it is exhilarating. The ride is dry and stable for its size. We cruised east towards Cabopino (7 NM) in under 20 minutes, then slowed for a swim stop in the clear water off Cala del Faro. The anchor is manual, but quick to deploy.
Who Is the Mariah SX21 For?
This boat is not for everyone. If you want a flybridge with a fridge, a sunpad for 12, or a cabin to escape the sun, look at our Azimut 58 Flybridge or Mangusta 80. The Mariah SX21 is for active groups who value speed and simplicity. It works brilliantly for:
- A couple wanting a private two-hour sunset cruise.
- A small family with older children who want to swim and waterski.
- Friends who want to explore the coast without a big budget.
- Photographers or videographers who need a fast, low-profile platform for shooting along the Golden Mile.
Where Can You Go?
From Puerto Banús, typical routes include:
- Cabopino (7 NM east): sandy beaches, the dunes, and beach clubs.
- Estepona (12 NM west): old town views, marina, and swimming spots.
- Marbella Marina (3 NM east): quick run for a drink or lunch.
- Río Verde and Cala Cortés: secluded coves for swimming.
For a 4-hour charter you can easily reach Cabopino, stop for a swim, and return. An 8-hour charter lets you push to Estepona or Sotogrande with a longer lunch stop.
Inclusions and Practicalities
Every Mariah SX21 charter includes:
- Licensed skipper (included in price).
- Fuel for the trip.
- Water, soft drinks, beer, white wine, and cava.

You are welcome to bring your own food and drinks. There is no fridge, so bring a cooler if you have special items. The boat has a small storage locker for bags. No toilet – plan beach stops for comfort breaks.
