Delta Powerboats 33 Coupé Review (2025 Edition) by Aquaholic

On Deck

The Delta 33 Coupé is right in the middle of Delta’s range, which runs from compact 7.9m (26ft) boats up to 26.8m (88ft) models. At 10m (33ft), it is a narrow, sleek machine and it looks like it wants to go fast even when tied up. This example marks the UK premiere of the Coupé. The open version is effectively the same boat, just without the roof, which is probably the simplest way to describe it.

The overall feel is purposeful rather than flashy. Instead of stainless rubbing strakes, Delta fits a thick rubber rubbing band, which makes sense on a boat that will likely see regular use. The cleats are a highlight. They are beautifully made, sculptural pieces that feel more like small bits of design than deck hardware.

At the stern, access comes via the bathing platform with a boarding ladder and proper grab handles. The aft seating includes a simple flip-over section that turns into a sunbed. It is quick, obvious, and works exactly as intended. There is another small seat aft, and storage is dotted everywhere. Under-seat lockers hold the gas bottle and space for canopies. A full cockpit enclosure is available, which feels like a sensible option for UK boating.

Side decks are usable and feel secure thanks to proper rails. Fender sockets are built into the topsides, allowing fenders to drop straight into place using pins, keeping everything tidy. Forward on the bow sit the anchor gear and controls, along with the hatch for the owner’s cabin below.

Up top, the roof carries radar, searchlight, and antennas raked aft for a small performance gain. Navigation lights are neatly integrated into the hull sides. A dynamic positioning system is fitted, using GPS and joystick control to hold the boat on station at the press of a button.

The cockpit and saloon are on one level beneath the hardtop. This boat has the optional powered fabric sunroof and a single button at the helm opens it fully. Because it is fabric rather than a solid panel, the opening is large, giving plenty of air and light on a good day.

Seating centres around a convertible dinette. This boat has the optional high load table, specified so the area converts into a sleeping berth. As standard, the table leg is fixed. The tabletop folds, and the teak finish shows careful attention to detail, with the grain running neatly through the panels. The helm seat has lift-up bolsters and a reversible backrest. Drop it flat and it becomes part of the dinette, turning the cockpit into a proper dining area.

The galley sits to port. There are racked lockers for crockery, dedicated cutlery drawers, and secure glass stowage, which matters on a boat capable of serious speed. There is a small sink, a two-burner gas hob, and a decent-sized fridge below. The gas bottle locker is accessed from the cockpit. A Fusion stereo is mounted nearby.

At the helm, large multifunction displays dominate the dash, appearing to be around 40.6 centimetres. Typically, one runs navigation and the other engine data, though layouts are configurable. Engine controls sit alongside joystick control for the sterndrives. Bow thruster control uses push buttons rather than a conventional joystick. Switchgear for lights, wipers, and the roof sits close to hand. Visibility is good thanks to slim windscreen mullions and a wide glass area. The steering wheel carries the Delta logo and feels properly weighted.

Access to the lower deck is through a sliding door. On the open version, this entire area remains exposed, with the lower accommodation closable instead.

Owner's Cabin

The forward owner's cabin has a clear Scandinavian feel, with light headlinings, pale side panels, and restrained teak trim. Shelves run along the sides, with additional storage beneath the berth. The space feels calm and uncluttered rather than dressed up.

A sliding door closes the cabin off. Inside is a wardrobe and a full-length mirror. For a 10 metre (33ft) boat, the proportions feel good, and natural light comes in through the hatch above.

Guest Accommodation

The guest cabin sits beneath the cockpit and houses a transverse double berth. The infill cushion for the cockpit table berth stores here. Storage continues under the mattress and within side alcoves. Lighting is good, and the space feels practical and usable.

Between the cabins sits the heads compartment. It is a good size for a boat of this length. A separate shower enclosure closes off behind a screen, with the toilet outside it. Storage lockers are spread throughout, and a window brings in natural light.

Opposite, a systems panel houses the CZone boat control system, alongside light switches and USB charging points, allowing phones to be dropped in and charged neatly.

Additional hanging lockers are built into the lower deck, adding useful storage without clutter.

Engine access comes via a powered cockpit hatch. A joystick is also fitted topside, giving close quarters control from the cockpit when berthing.

This boat is fitted with twin Volvo Penta D4 320 diesel engines driving sterndrives. Performance is a key part of the package. Top speed is around 83.3 kilometres per hour, or 45 knots. The hull is stepped, narrow, lightweight, and stiff, all clearly aimed at speed.

Efficient cruising sits around 48.1 kilometres per hour, or 26 knots, giving a range of roughly 563 kilometres, or 350 miles. With a top end like this, cruising in the mid 30 knot range is easy.

Alternative engine options include a single Volvo Penta D6 mounted on the centreline. This six-cylinder option frees up space around the engine and reduces running costs through single-engine servicing and fuel use. Twin outboard installations are also offered, with twin 600 horsepower Mercury Verado V12s pushing top speed beyond 92.6 kilometres per hour, or 50 knots.

The engine space houses fuel filters, fire suppression, and a portable dehumidifier. There is no generator. There is no air conditioning. Cooking is gas. All systems and lighting run from the batteries, charged via shore power.

Battery switches for both engines and service batteries sit just inside the cockpit door, alongside cockpit, deck, and saloon light controls, all easy to reach on entry.

Owning a 10m (33ft) sports cruiser means thinking beyond purchase price to the costs and commitments that come with regular use and mooring. Warranties on new craft like this usually cover hull and major systems against defects for a set period from delivery to the first owner - clarity on exact terms, exclusions, and claim processes is important before you sign. Warranty work typically does not cover normal wear and tear, misuse, or damage caused by non-authorised parts. Extended third-party plans can cover mechanical breakages after the factory warranty ends and, in some cases, parts of haul-out costs.

Annual running costs can often land around 10 to 20% of the boat’s value once you add berth fees, servicing, insurance, winter storage, fuel, safety gear updates, and depreciation. Berthing fees vary widely by region; on the South Coast of England, marina charges for a boat this size can run into the thousands each year. Insurance usually sits at about 1 to 2% of insured value for hull and liability cover, and most marinas require proof of insurance before you can occupy a berth.

Routine engine and systems servicing, antifouling, safety equipment replacement, and haul-out for checks form the baseline upkeep. Owners who do some maintenance themselves will cut some bills, but professional servicing remains a regular cost. Depreciation on new boats tends to be front loaded, with the biggest drop in value in the first few years.

Other purchase-time costs include survey fees, financing charges if a loan is used, and any transport to and from the dealer for warranty work. The location of your base makes a real difference; a nearer berth reduces travel time and lowers transport or haul-out fees, while a well-set-up home marina simplifies routine care.

In short, plan realistic budgets that cover more than fuel and occasional servicing. Understand exactly what the builder warranty covers and compare that with third-party plans. Factor marina costs, insurance, maintenance, and depreciation into your ownership plan so there are no surprises down the road.

Two similar boats you might weigh against the Delta for performance and accommodation are the 10.3m (around 34ft) Windy Boats W34 Alizé and the 10.07m (around 33ft) Riva Aquariva Super.

The Delta 33 Coupé is very clearly about speed, but it does not forget how the boat will actually be used. It combines a fast, narrow hull with a cockpit that works, proper deck hardware, and accommodation that supports overnighting.
