Personalized Service

The onboard staff includes the captain and a host. Poseidon is equipped with watersport equipment and diving gear for up to four people.

A buffet and drinks are included on every charter trip. The services of the Private Boat, Private Diving and Private Grotto Charters are bespoke, which means that the drinks and water activities are chosen by you. Once you’ve booked your trip, our dedicated service team will reach out to help plan your day. When chartering Poseidon, we cater to everything. All equipment for diving or other water activities, food and drinks, beach towels and sunscreen are already in place when you board. We assure that you can simply arrive and enjoy a totally effortless day.

Designed for Outdoor Comfort and Water Access

Poseidon X is a classic entry-level cruiser, which is well-regarded for its efficient use of space, providing amenities typically found on much larger vessels within a manageable 25-foot frame.

The outside area provides a large sunbed that fits four people, a warm-water shower, a reinforced sea level platform with a bathing and a diving ladder. Further there are racks to transport scuba diving bottles safely.

Poseidon X’s wide beam contributes to a spacious interior. The layout includes a forward V-berth, and a mid-cabin dinette in the main salon, a full gallery as well as an enclosed toilet space.

There are a fully integrated first aid kit and oxygen kit provided onboard, full navigation and electronic equipment and a crew of two qualified skippers/diving instructors.

A location for water sports enthusiasts

Lagos on Portugal’s Algarve coast is a premier destination for boat chartering and diving thanks to its unique natural beauty, wonderful year-round weather, diverse marine environment, and a local infrastructure catering to all water sports enthusiasts. The coastline around Lagos is famous worldwide for its breathtaking beauty, featuring dramatic limestone cliffs, sea caves, and hidden coves, particularly at the renowned Ponta da Piedade. These formations are best explored by boat, as many secluded beaches and caves are inaccessible by land. Poseidon Private Charters operates from one of Portugal’s most renowned marinas, Marina de Lagos. This marina has received multiple prestigious awards, recognizing its high standards in quality, safety and environmental sustainability. For Poseidon Private Charters, Marina de Lagos provides everything needed for smooth operations and unforgettable diving adventures.
