Yacht Description
Big cat, simple win. SIETE MARES is a 78ft Lagoon Seventy 8 power catamaran delivered in 2025, set up to sleep 8 guests in 4 en-suite cabins. The payoff is the volume: you can actually spread out, rather than take turns.
Water access, sorted. The hydraulic swim platform makes getting in and out of the sea feel less like a gym class. Add the outdoor shower and you can go from saltwater to lunch without importing half the ocean inside.
Outdoor living that works. There is an extensive flybridge with seating, sun loungers, and a bar, plus dining options inside and out. Short version: everyone stays in the same orbit.
Toys for all ages. You get a Williams 4.57m tender, plus a properly loaded toy box including an e-foil (use permitted with signed waiver), 8 sea scooters, wakeboards, water skis (adult and kids), a towable tube, SUPs (including sail kits), a 2-person kayak, snorkel gear, fishing gear, and a floating dock.
Cabins with logic. The layout is flexible: three queen-bed cabins plus a twin that converts to a queen, and every cabin has a TV. Good for families, or couples who do not want to draw the short straw.
Broker Review
Onboard visit
SIETE MARES is stunning, with a style that's genuinely well executed throughout. Her yacht hostess, Sarai Ben Ari, won this year's tablescape competition with a strikingly original Nordic theme. This year alone, SIETE MARES picked up four awards, including Best in Show for her size class, Best Flavoured Water, and Best Dessert.

Christmas 2025 BVI Charter
What a spectacular week aboard Siete Mares with the most amazing crew ever! From sunrises to sunsets, every day was filled with adventure, efoiling, sea scooters, stand up paddelboards, kayaking, waterskiing, scenic hikes, and the grounding, soul centering yoga practice led by Sarai. Each experience felt perfectly curated and balanced, exhileration and calm in the most magical way.
And then of course there was Kiki's food - simply unforgettable. Every meal somehow outdid the last with imaginative tablescapes and stunning presentations that made each gathering into a celebration. The flavors, the creativity, the care - pure artistry. (And the never ending, self filling snack baskets, legendary)!

Our charter experience this past week can only be described as perfect. The boat is gorgeous, impeccably decorated, and maintained, and every second we spent here was a joy. The real star of our trip was the crew, who we can’t thank enough. From Bastian’s captaining, Chanry’s service and wine pairing, Sarai’s bartending and yoga practice, and Davide’s incredible meals, each crew member is a true master of their craft. We were deeply impressed by the confident grace with which you all worked. Congrats on a successful first charter with Siete Mares, thank you for making it special, and here’s to many more in the future!

Bastian & Sarai - From the moment we stepped onto this beautiful vessel, we could not have felt more welcomed by you both. To say that this is just a 'bucket list vacay' does not touch the surface of this amazing week. The food was DELICIOUS! Even with all of our picky likes and dislikes, Sarai was able to "WOW" us all with her amazing meals. Bastian dazzled us with his abilities to make the best cocktails, as well as being a superb captain, taking us from island to island.
We could not have asked for a better crew. You have been the key to making our vacation an adventure of a lifetime which we will never forget. We have enjoyed our conversations with you both, and are in awe of your worldly travels and experiences. We would love for our paths to cross again some day!

Dear Bastian & Sarai,
Reflecting on our 40th Birthday journey in the BVI will forever bring a grin to our faces and a glow to our hearts.
Bastian, your skills in navigating the seas were nothing short of impressive. Your calm demeanor and leadership was very appreciated as it helped relax our group.
Sarai, your culinary wizardry had us convinced we were dining at a Michelin star restaurant on the high seas. I swear your poke bowl had us singing its praises louder than the ocean waves. Somehow you read our minds when prepping our menu.
As you both continue on your journey, we wish you nothing but smooth sailing and endless culinary delights.
