Mariah SX21 Charter Marbella — Compact Bowrider for Small Groups

The Mariah SX21 is a 6.4 m American bowrider at Puerto Banús — fast, sporty, and built for small groups (up to 5). Water-sports capable, lowest entry price in the motor-boat fleet.

The Mariah SX21 is the compact water-sports option in the BoatHire24 Marbella fleet — a 6.4-metre American bowrider designed for the kind of active, high-energy day on the water that larger motor yachts can't deliver as efficiently. For small groups (up to 5) who want water-sports activities as the focus of their charter rather than a backdrop to a social day, the SX21 is the right tool.

Specifications

  • Length: 6.4 m (21 ft)
  • Capacity: Up to 5 guests
  • Builder: Mariah (USA)
  • Type: Open bowrider
  • Features: Water-sports tow point, open cockpit
  • Departure: Puerto Banús, Marbella

Water sports from the SX21

The Mariah SX21 is rigged with a tow point for water-sports activities — banana rides, inflatable donut runs, and beginner wakeboarding are all viable from this platform. For groups of 2–5 who want to spend two to four hours doing these activities rather than sunbathing and anchoring, the SX21 delivers this more economically and directly than any larger boat in the fleet.

Bowrider layout

The defining feature of a bowrider is the open seating area that extends forward into the bow — passengers face aft or sideways in the bow section, which provides a genuinely exciting ride at speed and an excellent swimming entry point when the boat is stationary. The layout is more intimate and sport-focused than the cockpit layout of a larger motor yacht.

Best use cases

The Mariah SX21 is well-matched for couples and small families doing a short coastal hop and swim stop; for watersports days with 3–4 active participants; and as a budget-conscious entry point into Puerto Banús charter for groups who want a skippered experience without the price of a larger boat.

It's worth noting that the SX21's small size means it's more affected by sea state than the larger boats — in conditions above Force 3, comfort and watersports performance both reduce. The skipper will advise on the day.
