A grand entrance

Barry Thompson | VOLUME 31, ISSUE 2

Integrity has broken with its tradition and launched a semi-displacement hull that adds speed to its comfortable and stylish range of motoryachts.

Integrity Managing Director, Brett Flanagan, and National Sales Manager, Peter Hill, seem to be able to read the market perfectly. Having sold 55 boats in under five years into Australia and New Zealand, and with over 14 boats on order, interest in all their models is higher than ever.

“We don’t build superyachts and high-end passagemakers. Rather, we have concentrated on displacement cruisers with a world-class finish and with an Australian price tag,” says Brett.

“The Grand Sedan range came about from feedback and input from existing clients. Some of our owners wanted to move up in size, but they also wanted a boat that was a bit quicker.”

With all previous Integrity models based on displacement hull designs, there was obviously a limit to the speed factor, so something new was required. The 47.5ft (14.5m) 460 Grand Sedan, launched in August, is the Australian-designed, semi-custom, semi-displacement luxury cruiser that fills that gap. A 460 Raised Pilot House is also due to arrive soon, as well as a larger 490 (49ft/14.9m) version in both Sedan and Pilot House models.

“While it wasn’t in our DNA to go from full displacement to semi-displacement, it was a natural progression and we decided that it would also be a good time to upgrade everything from the engineering to the layout and external look of the boat,” says Brett.

Underwater, the new 460/490 retains the same keel as the Integrity displacement models, but has been given a tweak on the aft running surfaces to feed more clear water to the propeller and, with the new semi-displacement hull form, provides a gain of six to seven knots over the displacement hull.

On initial trials, the 460 Grand Sedan achieved 17 knots (31.5km/h), running the latest 480hp Cummins QSB5.9 in-line six-cylinder. This is a Tier 2 compliant engine and is available from 330hp to 480hp. The fuel tank takes up to 2000lt.

Mechanically, much has been retained from the displacement models, although the Quick bow and stern thrusters have been increased from 4hp to 8hp. Extra insulation has been added to the engine room and, when you run the 460 Grand Sedan, you can’t help but be impressed with just how quiet the boat is.


There is a certain refinement about the 460 Grand Sedan that sets it apart from the rest of the Integrity fleet. It offers a variation on the traditional layout and extra sophistication in the finishes from the existing Integrity range. The rearranged saloon, galley and helm areas still feature the open-plan, entertaining-style layout, but with a few design enhancements to create an inviting, comfortable living space.

A big change has taken place in the helm station, which is now 1.5m wide and comes with a matching double-bench seat. A pair of Raymarine 16in screens highlight the electronics package, with plenty of space for every conceivable extra in electronics, switches and so on that you’d want to add for longer-distance cruising. Fusion and Bose take care of the sounds.

There’s also a new side door for ease of access to the side decks. An icemaker and storage take up space under the helm seat. The side decks have been widened and the solid handrails make you feel safe when accessing the foredeck area.

The galley is massive and runs the full length down the portside of the saloon. It comes with twin Waeco fridges, convection microwave, two-burner cooktop and Corian vanity top with dual sinks. There’s a pop-up TV at the rear of the galley which can be swivelled, so viewing is possible from throughout the saloon and cockpit.

The L-shaped settee opposite the galley is also generous in size and comes with storage drawers underneath. The owner chose not to have a dining table fitted inside, although there is one in the cockpit. The layouts are very customisable – the galley/lounge area can be reconfigured to take a table, which allows for another double berth with an adjustable high/low table base.

For me, the 460 Grand Sedan’s pièce-derésistance is the factory-made lift-up rear hopper windows, which open up the entire rear of the saloon. The cockpit and saloon become as one and present a huge entertaining area that says “let’s party!”

The rear deck layout has not changed from previous models, with 3m of very useable space, right through to the aft seating and access to the boarding platform. Seating either side has storage underneath and the table can drop down to give yet another berth. All up, if you have the twin table arrangement, there is sleeping for eight.

The lazarette entry in the cockpit sole is now further forward and three times the size. The cavernous space is almost big enough to transform into a dinghy locker and gives great access to a lot of the engineering systems, such steering and AC/ DC panels, and a Waeco 80lt deep freeze.


The Integrity 460 Grand Sedan has a two-cabin, one-bathroom layout, whereas the 490 offers three cabins and two bathrooms, with a separate en suite for the owner’s cabin. The interior finish in the accommodation areas has been kept soft and appealing with light semi-gloss horizontal timber panelling. You have the choice of other timbers such as teak and cherry wood, in any finish, from satin to high gloss.

The forward cabin can be configured in a variety of ways, from the standard central island berth to a twin V-bunk arrangement, as chosen by the owner of this boat.

The starboard owner’s stateroom, with a walk-around island berth, is an interesting layout that makes excellent use of the available space. Dual sliding timber doors divide the large cabin from the offset companionway, which sees the shared bathroom on the port side. If there’s just a couple aboard, you can open up the accommodation area or slide the doors shut for privacy.

The owner’s cabin has all the usual amenities such as cedar-lined hanging lockers, drawer and under-bed storage, TV and plenty of natural light from big side windows and a frosted overhead skylight.

Brett has increased the number of steps from the accommodation area to the saloon from three to four. “It’s a little thing,” he says, “but the extra step and solid handrails either side make the transition from either area just a little easier.”


With its new semi-displacement hull, the 460 Grand Sedan is attracting a new wave of owners keen for the best blend of classic attributes with contemporary styling. This is a boat that lends itself to casual, unpretentious cruising, with all the necessary comforts.

The 460 Grand Sedan, and the shortly to be released 490 Grand Sedan, will certainly suit the more senior owner, with everything pretty much on the same level and with ease of access to all areas, from the engine room and lazarette, to the accommodation and side decks. It’s a very easy boat to operate and practical in every respect.
