Siete Mares, a brand‑new 2025 Lagoon SEVENTY 8, represents the pinnacle of contemporary yacht refinement. Outfitted under the guidance of a professional outfitting team and perfected by an experienced crew, every detail has been shaped with intention. From the chef’s beautifully organized galley to the elevated presentation of each meal, the yacht has been designed to deliver a charter experience defined by comfort, precision, and effortless indulgence.

Accommodating up to eight guests, Siete Mares offers four versatile staterooms, each with its own en‑suite bathroom, television, and premium stereo system. The interior is warm and sophisticated, featuring hardwood decking, a galley‑down layout that enhances privacy, a fully stocked wet bar in the salon, and an inviting lounge with a retractable 55‑inch flat‑screen TV. Guests may dine indoors or alfresco, with menus tailored to personal tastes and crafted with the finesse of a private restaurant at sea.

The yacht’s amenities elevate every moment on board. A 15‑foot Williams tender with 110 HP ensures smooth transfers and thrilling excursions, while a hydraulic lift, advanced water treatment system, and reef‑safe toiletries reflect a commitment to both comfort and sustainability. The selection of water toys is exceptional: water skis, a wakeboard, a two‑person kayak, four stand‑up paddleboards that convert to windsurfers, and eight underwater scooters for exploring the sea with ease. A floating dock, yoga mats, exercise equipment, and a bar stocked to guest preferences create a resort‑like atmosphere on the water. Deep‑sea fishing gear, snorkeling equipment, board games, card games, and rendezvous scuba diving complete the experience.

Every element of Siete Mares has been curated to offer a seamless blend of luxury, adventure, and personalized service. Whether you are lounging on deck, savoring a gourmet meal, or discovering the underwater world, the yacht provides an environment where unforgettable memories unfold naturally.

FAQ about WI Yachts

We can bring you anywhere in the world. From the true and tested Caribbean or Mediterranean destinations to the less explored areas such as the Pacific Islands, SE Asia, the Indian Ocean, and even adventure destinations such as North America or North Europe. Get in touch with our team if you don't find your desired destination in our list.
We are headquartered on the French Riviera, but we organize yacht charters worldwide. We have representatives around the world including in the USA, in China, in Hong-Kong, in the UK, in Italy, in Spain and in Germany. Feel free to contact us if you want to get in touch with one of our team member on your time zone or in your language.
Of course! We organize yacht charters for people with different sailing experience levels. If it's your first time stepping on a boat, we’ll make sure your first charter is comfortable, enjoyable, and tailored to your needs.
Yes, we can provide a skipper or captain for our bareboat rentals. For bigger yachts, the crew is included in the price.
Bareboat Charter only includes the yacht and insurance. Crew (including skipper) and provisioning are extra. A deposit and any selected options are due upon delivery.
With us, you’re never just a booking number. We are a family-run business simply all-in into sailing: when we are not organizing your charter, we are attending yachting festivals to find the latest model releases or testing new sailing destinations. The result? Customers that charter with us once rarely go anywhere else for their next sailing trips. We have loyal customers that have been with us for decades!
