SIETE MARES Yacht Description
-
Inflatable Jet Ski Dock:
Rare for catamarans, this offers guests easy and exciting access to jet skis for water fun. -
Eight Sea Scooters (Seabobs):
Premium underwater scooters for guests to explore marine life while snorkeling or diving. -
E-Foil Board:
The latest and most popular water toy, perfect for thrill-seekers to glide above water.
Start with the balcony that drops out of your bedroom. SIETE MARES’ master suite has a fold‑out private terrace at water level, so your morning coffee and your evening swim share the same horizon line. This is a 78ft Lagoon Seventy8 power catamaran built in 2024, so you’re not getting “classic charm”; you’re getting current‑gen design, fresh systems, and a layout drawn around actual human comfort, not brochure poetry.
Then factor in the footprint. The 36ft beam is basically legalized cheating: a sunken foredeck lounge that behaves like a beachfront living room, a full flybridge with hardtop, bar and dining, and a main salon that doesn’t make you choose between views and air‑conditioning. Four ensuite cabins sleep up to 8 guests, with flexible twin/queen options and TVs and media in every cabin for when “togetherness” has run its course.
Now layer on the toys and the hardware. Eight sea scooters, e‑foil, wakeboards, skis, windsurfers, SUPs with sail kits, floating dock, fast Williams tender, hydraulic swim platform, rendezvous diving, fishing kit, yoga mats, bands, dumbbells. Translation: the water around the yacht is basically an operating system and you have root access.
Finally, the human software. A pro crew of four—including an ocean‑lifer captain, a fine‑dining/Michelin‑trained chef, a sommelier‑grade host team and a dedicated wellness/yoga focus—means cocktails, menus, and daily rhythm are tuned to you, not the other way around. Bar stocked to preference, fully custom menus, reef‑safe products, Wi‑Fi, and full AC keep the experience firmly in the “civilized expedition” category.
If you want a modern 8‑guest platform where the master suite turns into its own mini‑beach club, the decks behave like a small resort, and the toy locker looks slightly illegal, SIETE MARES is the logical choice.
Accommodation

Reviews
You guys are fantastic and we don't think we will ever find a crew as thoughtful as you.
You literally thought of every detail to make the experience perfect... you made our vacation unforgettable! We will cherish the memories we made on this charter forever. From the impeccable meals, yoga morning sessions to the unforgettable scenery, we really loved every second.
The perfect boat, the best crew, thanks so much again!
From the yogi mornings; to the love + passion put into each meal prepared and served; to
the patience + joy sailing +
playing with our children. A special thanks for the thousands of teas brewed + the daily surf reports + guidance. We were able to stay in the moment + share memories that will last forever. The route chosen through the BVIs was perfect.
Much Love
Thank you so much for another incredible week in the BVI. Of course the boat itself is
incredible. We had all the space + toys we could possibly need. But more importantly,
you the crew helped to make this another unforgettable time for our family. You
prepared + predicted for our every need. We loved learning to use the e-foil, snorkeling
in every possible spot, and the yoga was an amazing way to start the day on the boat.
This is our third vacation with you and each trip has been better than the last. Thank
you so so much for creating another wonderful family week for us.
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!
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.
