Top 3 Grenadines Yacht Charters for 10 to 12 Guests
Introduction
Chartering the Grenadines with 10 to 12 guests requires more than simply finding a yacht legally capable of accommodating the group. Six well-proportioned cabins, enough crew to deliver consistently attentive service, multiple communal areas and sufficient space for everyone to spread out become increasingly important as the group grows.
The best options can also turn the yacht itself into one of the highlights of the holiday, with swimming pools, Jacuzzis, waterslides and extensive toy collections complementing days spent around Mustique, Canouan, Mayreau and the Tobago Cays. These three yachts stand out among the strongest Grenadines charter options for groups of 10 to 12 guests.
OKTO
At 66.4 metres, OKTO is comfortably the largest yacht in this selection and our number-one choice for a 12-person Grenadines charter when budget is secondary to the quality of the experience.
Built by ISA Yachts and freshly refitted in 2026, OKTO accommodates 12 guests in 6 cabins and can operate with a crew of up to 16. That crew-to-guest ratio is exceptional and makes a significant difference when twelve people are onboard. Her four-deck layout also gives a large group far more room to separate, while an elevator connects the guest areas and makes movement around such a substantial yacht considerably easier.
The centerpiece is a spectacular 20-foot infinity-edged swimming pool that connects visually with the main saloon, creating something closer to a private beach club than a conventional aft deck. There is also a Jacuzzi, gym, sundeck, dedicated cinema and formal dining for 12. The toy inventory is equally serious, with two Jet Skis, two SeaBobs, two eFoils, wakeboards, wakesurf equipment, paddleboards, kids' waterskis, banana boat, inflatable trampoline and climbing structures, plus snorkeling and diving equipment.
St Vincent and the Grenadines is included within OKTO's charter zones, while her published weekly rate runs from approximately €590,000 to €620,000. For twelve guests seeking a genuine large-superyacht experience rather than simply accommodation for a larger party, OKTO is on another level.
YCM FIFTY
YCM FIFTY is arguably the most practical yacht of the three from a pure accommodation perspective.
The 50.29m Oceanfast motor yacht sleeps 12 guests in 6 ensuite cabins, split evenly between three king cabins and three queen cabins. That is an excellent configuration for six couples or a multi-generational group because there are no obvious compromises in the guest accommodation. She carries up to nine crew and underwent a major refit in 2024.
YCM FIFTY also combines substantial size with surprisingly strong performance. She cruises at approximately 12 knots but can reach a stated top speed of 30 knots, giving the captain considerable flexibility when moving a large group between Grenadine islands. Her relatively shallow 1.55m draft is another unusual advantage for a 50m yacht in an anchorage-focused cruising ground. Onboard amenities include a Jacuzzi, while the toy inventory adds a waterslide, four paddleboards, SeaBobs, snorkeling equipment and waterskis.
St Vincent and the Grenadines is explicitly included within her charter destinations, and the published rate is approximately €150,000 per week. For a group of twelve that wants six proper double cabins, superyacht service and significantly more approachable pricing than OKTO, YCM FIFTY is an exceptionally strong option.
CUPCAKE
CUPCAKE takes third place, but she may actually be the most entertaining option for a group that intends to spend most of the charter in the water.
The 40.3m Westship accommodates 12 guests in 5 cabins, including a full-beam owner's suite with king bed and Jacuzzi bathtub. The remaining accommodation includes another king, two queens and a flexible fifth cabin with a queen, twin and Pullman, which makes the layout particularly useful for families or mixed-generation groups rather than six couples requiring identical cabins. Her main saloon includes formal dining for 12, while the skylounge and large sundeck provide separate social spaces for a full charter party.
CUPCAKE's water-toy inventory is extraordinary. She carries SeaBobs, WaveRunners, multiple paddleboards and kayaks, a waterslide, floating swimming pool, towables, wakeboards, waterskis, extensive snorkeling equipment and a complete beach dining setup for twelve. A large 41ft Nimbus tender and 20ft beach-landing tender make shore excursions and beach days particularly easy for a larger group. Back onboard, guests have a Jacuzzi, wet bar, skylounge and extensive sunbathing areas.
St Vincent and the Grenadines appears within her charter zones, with weekly rates from approximately $132,000 to $152,000. CUPCAKE does not offer the six equal guest cabins of OKTO or YCM FIFTY, but for a family or mixed group of 10 to 12 guests prioritizing water toys and an energetic Caribbean charter, she is difficult to beat.
