Broker Review

Onboard visit

Onboard luxury catamaran SIETE MARES in the BVI. They do half the year in the Caribbean and the other in the Mediterranean.

The boat is absolutely beautiful, and the style is well executed. The yacht hostess Sarai Ben Ari won this years tablescape competition with her Nordic theme - something I have never seen before, and instantly took me back to my childhood in the countryside of Denmark.

But that is not all, SIETE MARES won a whole 4 awards this year (2025), including 'Best in Show 62-80ft,' 'Best Flavoured Water,' and 'Best Desert' - This leaves us no doubt that SIETE MARES is a great boat.
