Delta 33 Open
Open space. Sporty performance. A weekend without limits.
Over 40 knots. Two cabins. Four berths. Up to eight people on board.
The Delta 33 Open is designed for those who want to spend more time on the water – without giving up the excitement, space and freedom of an open boat.
Its sleek profile, deep hull with a double-step design and hydrodynamics developed by Mannerfelt Design create a boat that is fast, stable and exceptionally rewarding to drive. The open layout allows you to make the most of life on the water – from an early morning run and watersports, to lunch at anchor and sunset with family and friends.
The Delta 33 Open is a dayboat that does not end its day when the sun goes down.
Also available as a T-Top
For those looking for even greater versatility, the Delta 33 is also available in a T-Top configuration – combining the open character of the 33 Open with additional protection and an even more sporting character.
The Delta T-Top is a synthesis of the Open and Coupé concepts. It combines performance and handling inspired by racing boats with generous space for socialising and the comfort needed for longer trips.
Our favourite is the twin Mercury V10 configuration, which fully unlocks the potential of the hull designed by Mannerfelt Design. Low weight and an optimised wetted surface allow the boat to reach up to 55 knots, while maintaining a comfortable cruising speed of more than 40 knots.
The distinctive T-Top provides protection from the sun, while a specially designed enclosure can be fitted to fully close the cockpit when needed, protecting it from the elements.
The T-Top shows just how far the Delta 33 concept can be taken – from an open dayboat to a 55-knot sports cruiser with genuine comfort on board.
Designed for life on board
The Delta 33 Open is built around one idea: maximum space and freedom within 33 feet.
Wide walkaround passages make it easy and safe to move around the entire boat, while the open transom creates a natural connection between the cockpit and the generous bathing platform. An integrated freshwater shower makes getting into the water, swimming and stepping back on board a natural part of every day.
At the stern, a large adjustable sofa can serve as comfortable seating, a generous sunbed or part of the dining area, depending on how you use the boat.
One space. Several ways to use it.
At the centre of the cockpit, a fully equipped galley makes lunch at anchor or dinner on board effortless.
Sun, water and space
The open layout is the defining strength of the Delta 33 Open.
There is no clear boundary between the cockpit, bathing platform and the water. Start the day with breakfast around the table, head out at full speed a few minutes later, stop for a swim in a quiet bay, then turn the aft deck into a relaxed social space as the evening begins.
The Delta 33 Open is designed around the way we actually use a boat.
It is not only about where you can go.
It is about what you can do when you get there.
More than a dayboat
Below deck is where the character of the Delta 33 Open changes.
Two separate cabins provide four comfortable berths, while a dedicated bathroom with a separate shower adds the comfort needed for longer stays.
A day on the water can easily become a weekend away.
No hotel to book.
No need to return to the marina before dark.
Simply stay on the water.
Independent testing of the Delta 33 Open highlights precisely this quality: it remains compact enough to be easy to handle and accommodate in a marina, while offering everything needed for occasional overnight and weekend trips.
Designed to be enjoyed
Behind the design of the Delta 33 Open are Ted Mannerfelt and Mannerfelt Design – and the character of the boat is best understood from the helm.
The lightweight hull, low wetted surface and carefully refined geometry provide an excellent power-to-weight ratio. With a Volvo Penta D6-440, top speed is approximately 39–43 knots, with fuel consumption of around 1.55 l/Nm at 30 knots.
The Delta 33 Open is also available with twin Volvo Penta engines and the full range of Mercury Verado outboards, allowing the boat to be configured to suit the desired character – from efficient cruising to maximum performance.
For those who want to unlock the full potential of the hull, a twin Mercury V8 configuration allows the boat to exceed 50 knots.
But this is not a boat designed simply to be fast.
Its real strength is the way it combines performance with usability.
Technology that works in the background
At the helm of the Delta 33 Open, modern technology is there to support the experience rather than distract from it.
A Garmin Glass Cockpit with dual MFD displays, Mastervolt CZone digital switching, Fusion audio, bow thrusters and automatic Zipwake interceptors integrate technology in a way that reflects the Scandinavian approach to design: functional, discreet and free from unnecessary complexity.
The hand-laid teak deck and carefully finished details complete the experience.
Scandinavian simplicity. Sporting character.
The Delta 33 Open does not look like a typical dayboat.
Its low, sleek profile, confident lines and distinctive silhouette create a design that is both elegant and dynamic.
This is Scandinavian design in its most natural form: simple, functional and free from everything unnecessary.
Independent testing has highlighted the boat’s distinctive styling and sense of character, while also recognising the practicality needed to genuinely enjoy it over an entire weekend.
The Delta 33 Open is an open boat for those who do not want to choose between performance and comfort.
Fast when you want it.
Spacious when you slow down.
Ready for the day.
Ready for the weekend.
