NYE 2025 BVI Charter

The best boat with the best crew!
Our second time on Siete Mares was even better than our first time. We anticipated this trip during 2025 because we knew how special this would be.
Bastian, Sarai, Sylon, and Kiki created such a beautiful, relaxing, joyful experience for our family - a truly treasured time for us. We will always be grateful for the thought and effort put into each day. you are all so attentive and thoughtful in your details.
We are already looking forward to our 3rd trip together

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)!

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

⁠Siete Mares family,
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.

Thank you for your generosity, kindness and warmth during our stay with you. The love you showed touched our hearts deeply. We also felt the deepest sense of nourishment to be in your care. From Davide’s creative, delicious and colorful spreads to Bastian’s skilled and grounded leadership, to Chanry’s sweet, cheerful and loving support and Sarai’s sweeping foresight and passion for hospitality. To be with all of you is to feel safe and at home. Props to William as well for capturing the beauty of your vessel and connecting us all. We were honored to be a part of the journey. Wishing you all the blessings and good fortune. Thank you again for having all of us.

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.
