At the Cannes Yachting Festival 2025, Outer Reef revealed the very first 780 Adventure – their first steel yacht and the launch point for a new Adventure range. Explorer yachts often trade looks for long legs, but this one takes a different tack. Built in the Netherlands on a support-vessel platform, it’s designed to cross oceans yet carries a more modern look than you usually find in this sector.
The idea is simple enough: build a boat that can do the hard miles but still feel like a place you want to spend time. Up on the flybridge, there’s a superyacht flavour, while below the steel hull, tanks and systems are set up for passage-making. It’s a mix that makes the 780 stand out in Outer Reef’s line-up, and we wanted to see how well the two sides work together.
Review Video
The 780 Adventure is a big step for Outer Reef. Until now, its long-range cruisers were all GRP, built with that classic shippy look. This one is different. It’s the first Outer Reef in steel, constructed in the Netherlands by the Lynx Yachts shipyard for Outer Reef Yachts, a yard more used to turning out tough support vessels. And you feel that in features like the bank-vault doors, the hefty deck gear, and the removable fender bars that were originally designed for tenders.
Steel brings a new character to the brand. Yes, it makes the boat heavier (she tips the scales at around 107 tonnes), but the pay-off is strength, silence, and the sort of confidence you want if you’re running in remote places. It also means you can have integral tanks: 15,000 litres of fuel, giving her a transatlantic range. And unlike GRP, if you want to change a layout or even scale the design up or down during the build, you’re not tied to a mould. That opens up a world of flexibility for an owner.
The hull itself is a fast-displacement form. That’s why she’ll sit happily at 7 knots for 3,000nm, cruise at 10-11 knots day in, day out, and still push up to 12 knots on these smaller Cummins engines. If you want to go quicker, the yard will slot in bigger CATs and you’ll see 16-18 knots. Either way, the hull is designed to stay comfortable and efficient, and the big Vector fins stabilisers keep her level both on passage and at anchor.
Design work came from Bernd Weel in the Netherlands, giving the boat its exterior look, while the interior is by Julian Moore. That mix explains why it looks more modern than the Outer Reefs you might know - larger glass areas, clean styling - but it still works as a serious liveaboard.
This isn’t replacing anything in the Outer Reef range as it’s a new track altogether - the first of the Adventure series. Smaller and larger models are already on the drawing board. What the 780 shows is that Outer Reef can carry their long-range philosophy into a different material, a different look, and still deliver the practical, ocean-ready cruiser their owners expect.
The saloon feels cavernous for a 78ft boat - not only in beam, but in height. Big windows flood the space with light, so even when you’re sitting down on passage, you keep that connection to the outside.
The finish here is what the basic spec from Outer Reef is, and it's quite simple and pared back, almost a little sterile with the neutral palette. This should be easy enough to warm up with soft furnishings, but the strength lies in the space itself. There’s storage under all the sofas, a big TV where it’s easy to see from most spots in the room, and plenty of cupboard and drawer storage along the sides.
The dining arrangement is casual with a convertible table that drops for coffee or raises for meals. If you go for the extended wheelhouse version, you can opt for a more formal dining table inside. That choice depends on where you’ll use the boat: shorter cockpit, bigger saloon if you’re in colder climes, or the balance we see here if you’re cruising warm waters.
The galley sits amidships, slightly separate but still social. There’s an option to push it out to the full beam on one side, which gives you more galley volume but blocks off the side deck. As it stands, it’s compact but has a good-sized cooking space with extraction, a full-size dishwasher, and refrigeration on a scale you rarely see at this length. Two full-height units (one fridge, one freezer) plus more cooling downstairs and in the lazarette. That’s the kind of provision you need if you’re staying grid for weeks at a time.
And for owners who run with crew, there’s a partition door so the galley can be closed off. A side door gives the crew a route outside to move around the boat without crossing the saloon.
Down the main staircase, you land in a lobby that feels surprisingly big for a 24-metre boat. Even the passageways down here are wide, and headroom is generous.
Under the stairs is a proper storage room, not just a cupboard - somewhere to dump luggage or even set up a coffee machine if you don’t want to head up to the galley every time. Alongside sits a day head, and opposite a laundry room that’s more domestic than token, with a washer, dryer, and space to stack all the detergents, towels, and bedding.
It’s a reminder that this yacht is built for living aboard. You’ve got four cabins leading off this space, but the lobby itself still feels open, more like a landing than a corridor, and that gives a different impression to most yachts of this size.
Two Owner's Cabins?
Each of the amidships double cabins on our tour boat shares the same footprint. Each cabin could be considered an owner's cabin so take your pick, and both are impressively roomy given they sit side by side. There’s clear space around the bed to walk, and the ceiling height is well over 2m.
One bulkhead is given over to wardrobe storage, while the opposite side has a bureau with a TV above. Glazing is modest, which is in line with the explorer style, though an opening port can be specified. Every cabin runs on its own climate control, and the whole system is tied into CZone, so lighting, AV, and climate can be managed from a tablet or simple wall switch.
The bathrooms are compact but properly equipped, with a separate shower cubicle and a window to bring in light. A minor gripe is that the window doesn’t open as standard, so clearing steam relies on extraction. Noise is another point - with the engine room just aft, the generator can be heard through the bulkhead, so extra insulation would be worth considering.
Layout flexibility is built in. As shown, the two doubles plus two twins forward create four ensuite cabins, a strong charter setup. Switch the layout for a full-beam owner’s cabin amidships, and the space shifts towards a more private arrangement.
Guest Cabins
The forward twins keep up the sense of volume. Passageways here feel wide for a yacht of this size, and the cabins themselves don’t feel pinched. Beds are set low with the windows high above, which exaggerates the headroom and makes the space feel taller than it is.
There are drawers under the berths, a wall of wardrobes opposite, and a decent-sized bedside table between the beds with integrated lighting and repeat switches. Bathrooms follow the same pattern as the doubles but work a little better in this orientation, as the toilet isn’t hidden behind the door, so you gain a bit more room around the basin and the separate shower cubicle.
A couple of niggles show up here. None of the cabin doors pin back, so they swing unless you hold them or shut them - a small fix, but on a yacht at this level, you’d expect it not to be a problem. And while the cabins are comfortable, you do feel they’re smaller than the doubles aft. Even so, four ensuite cabins in this footprint remain a strong package, especially if charter use is in mind.
Crew Accommodation
Forward of the guest spaces there are two small bunk cabins, one either side, giving four berths in total. The bunks themselves are a reasonable size and not much of a climb up to the top. Headroom stays good even this far forward, so it doesn’t feel too squeezed.
Facilities are basic with a shared bathroom thatdoubles as a wet room, and opposite sits a small fridge and microwave. Storage isn’t vast, though there is a full-height locker. Some small frustrations too as the lower bunks get bedside tables, the uppers don’t, and that makes charging devices awkward.
The bigger issue is access. On this hull, the only way down is via the foredeck hatch, which means crew have to go outside and climb down even in bad weather. There’s an option to add an internal door from the guest lobby, and that feels essential. Without it, the space is compromised; with it, these cabins work far better - whether as crew accommodation or even as extra kid’s berths.
The helm is no-nonsense. One adjustable chair, an upright dash, and a pair of huge screens that carry everything you need. It’s just simple and effective, with throttles, thrusters, and autopilot controls falling to hand. If you want more displays, there’s space for them, but the setup as shown on our tour boat works cleanly.
The view is commanding as there's a tall windscreen forward and to the side, plus a starboard door that opens straight out to the side deck. When you’re docking or setting lines, that quick step out is invaluable. And because this is the business end of a serious cruising yacht, the whole space has that upright, practical stance. You sit here, and it feels like you’re ready to cover miles.
The desk behind the helm is nice and wide, fiddled along the edge, and makes a good navigation space. Spread charts across it, set up a laptop, or just use it as a quiet study. Storage runs below it, so there’s somewhere to keep the gear that goes with it.
The bathing platform is built in steel, with those big removable fender bars you’d normally expect on a support vessel. On a mothership, they stop tenders scuffing the platform, but here they’re just as useful when you’re launching or docking, and they stow neatly away in a locker when not needed. The scale of the platform is generous, and everything feels heavy-duty - from the hinges to the hydraulic hardware.
Cleverly, the platform isn’t only about water access. A vast hatch lifts to reveal the lazarette and, beyond it, the engine room. It’s not the quickest, but when it’s up, you get full-height access to a space that can be loaded up with kit. Seabobs, dive tanks, fishing rods, even bikes - it’ll swallow it all. The finish isn’t perfect yet, with things like a loose deck shower needing tidying, but the bones of it are impressive. You’ve got the sort of utility space you’d expect on something larger, and because the steel build allows so much volume aft, it feels like a proper working bay.
Cockpit
You’ve got two big chunky cleats on each side leading to the cockpit, with fairleads welded in, and a pair of winches to keep the lines tight. The boat’s beam gives you masses of deck space here, and what really catches you is the headroom. The deck height under the overhang is remarkable - it feels far taller than you’d expect on a 24-metre yacht.
Outer Reef’s GRP boats are already pretty flexible, but without moulded bulkheads, you can shift things around even more. On this boat, you’ve got split tables, corner seating, and loose benches weighted down so they can be moved about. Slide them aft and you’ve got a sun pad facing the wake, spin them forward and you’ve got a lounge facing into the saloon. Add side screens, and this becomes a sheltered place to sit at cruising speed without the wind whipping around you.
Side Decks & Foredeck
The side decks are wide, nicely protected, and on this boat, they run all the way round. If you go for the asymmetric galley layout, you gain interior space but sacrifice the walkaround on one side.
Forward, the space has more of a commercial air than a luxury one, and that’s deliberate. There's no teak here as it’s a working foredeck, set up to stow serious kit. The boat we saw carried a 4.5m (14.7ft) tender, but the crane is sized for a 6m (19.6ft) boat, and the deck can handle it. You could line up two jet skis side by side, or add a stand-up in behind. It’s designed to take weight and keep it low for stability, which pays off when you’re out in a swell.
Right at the bow, there's an enormous bosun’s locker - deep enough to climb inside. Chain, warps, even big inflatable fenders all coil away down there without any faff.
Aft of this, a chunky hatch lifts to reveal a ladder that drops straight into the crew cabin. On this hull, that’s the only access unless you specify the internal door from the guest lobby. In fair weather, it’s no bother, but if you’re a crewmember climbing in during a blow, you’ll wish for that internal link.
Sundeck
The sundeck shows how different this yacht is from a typical explorer. Think Nordhavn or Fleming, and you imagine a small upper deck, maybe a crane, and some seating. On the 780, it feels much more superyacht as it's big, open, and leisure-focused.
The staircase itself can be configured as external, internal, or both, but set to one side as it is on this boat, it doesn’t eat into the below cockpit space. Once you’re up, a huge sun pad runs across the beam, and the backrests are friction-weighted so you can slide them wherever suits. Midships, a fixed dining table spans the width and is close enough to the bar for easy service, and all of it is shaded by a substantial hardtop.
The bar comes fitted for cold storage, but you can spec in a grill if you want more cooking options up here. Forward, the seating area has the same generous feel with plenty of room for a group to settle in, sheltered enough to use underway. There’s also the option to replace that section with a second helm. It would be great for manoeuvring, and in fine weather, there’s nothing better than driving from a flybridge, in the breeze with the view all around.
The big aft hatch lifts on a switch. It’s not the fastest thing in the world, but when it’s open, you get brilliant access - you walk straight into a lazarette and then through into the engine room. If that fails or you’re at sea, there’s a ladder under the cockpit seating, so you’re not reliant on the one hatch.
The lazarette is enormous. Equally useful for stacking with cleaning gear, ropes, and fenders as it is for bikes, Seabobs, or dive kit. You could even rack it out for fishing. That’s the beauty of the space – you can make it whatever you need. A few details need tidying, like the deck shower hose just hanging loose, but the volume and practicality are there.
These smaller Cummins 425s look almost lost in here, which makes them easy to get at. Filters, hydraulics, generators; all of it laid out with space around it. Go for the bigger CAT C32s and you’ll fill it out more, but you also get the speed boost up towards 18 knots.
For fuel, there are two wing tanks, a day tank, and a main tank, all cross-linked and polishable. Twin filters are right where you want them, and the hydraulic pack sits central for thrusters and stabilisers. There are two gensets, one on each side. The watermaker has been pushed forward under the crew space, so this bay isn’t crammed with everything.
Yachts of this style don't come cheap, given the heft of the engineering required to build a craft as capable as this. To get a 780 Adventure to the spec of the boat we toured, you'll be looking at a price of around €6.6 million ex VAT, and that includes items like twin generators, a water maker, thrusters, fin stabilisers, a navigation package, and tender handling on the foredeck.
The nature of these bespoke boats, which are built with a heavy personal touch, means comparing prices is tricky, but the Outer Reef will likely undercut heavy hitters such as Nordhavn and Fleming. Though, as mentioned above, there are areas where you can see where those savings are made. The overall build seems solid enough, but the finesse is lacking in place, and naturally it's hard to pass full comment until we sea trial it.
Keep in mind, though, the steel build makes the Outer Reef far more customisable than those brands, which makes the price point all the more impressive.
Our Verdict
This is hull number one, and in places it feels like it - there are small details that still need tidying, and a bit of extra insulation wouldn’t go amiss. Outer Reef tried to modernise before with the Trident line; the Adventure 780 feels more resolved.
The 780 Adventure also shows where Outer Reef is heading. Styling that’s sharper than the dowdy look some explorers suffer from, but still a hull built to go the distance. The flybridge in particular feels every part of the leisure deck, while lower down, the build and systems have that heavy-duty character you’d want for remote cruising.
The YachtBuyer Score provides a clear, category-by-category assessment of how the yacht performs in the areas that matter most. In this review, the Outer Reef 780 Adventure receives an overall rating of 4 out of 5 stars.

Rivals to Consider
The Princess X80 is a high-speed enclosed flybridge from Princess’s X Class aimed at those who want planing performance with lots of luxurious space. It offers up to five cabins (or four in some layouts), including a full-beam master amidships, forward and guest doubles, and a twin with ensuite bathrooms in all cabins. It can carry around 8 guests comfortably (or up to 10 if you push the layout), plus crew quarters for 2-3. Under the hood are twin 1,900 hp MAN V12 engines giving a top speed around 30-31 knots, with cruising speeds in the mid-20s. The X80 has a relatively modest long-range compared to slower hulls - it’s built more for performance and coastal cruising than ultra-offshore passages. Unique features include its “super flybridge” with vast al fresco living, an elevated saloon with floor-to-ceiling glazing, generous side decks, and a design that aims to feel like a 30m yacht in a 25m package.
The Nordhavn N80 is very much in the explorer/passagemaker camp, rather than the high-speed flybridge genre. Its layout offers four cabins in many configurations (three guest staterooms plus crew) and can carry up to about 8 guests in comfort. Performance is modest: top speed is roughly 12 knots, with cruising speeds in the high single figures. Its strong suit is range - approximately 2,700nm at around 8 knots (or similar displacement cruising speeds), making it capable of long offshore legs without pushing the engines hard. Unique to the N80 are Nordhavn’s pedigree in seaworthy displacement hull design, emphasis on self-sufficiency, low vibration and heavy engineering, large fuel and water tanks and layouts that allow either a captain’s cabin behind the bridge or an upper-level owner suite, depending on the owner’s taste.
The Sirena 88 brings a different flavour: it's an SUV-style yacht with semi-displacement performance and strong guest capacity. It has five cabins, including a main-deck owner’s suite, and can accommodate up to 12 guests in party mode (though practical overnight capacity is more modest, depending on how you run the cabins), with crew quarters (for about 3-4). Top speed reaches about 25 knots, but if you slow down (to 9 knots or so), its semi-displacement hull gives a range of about 2,000nm, extendable to over 3,000nm with optional large fuel tanks. What sets the Sirena 88 apart are its bold SUV design by German Frers (sharp prow, aggressive glass), strong outdoor entertaining spaces (huge flybridge, a “beach club” style stern/transom, foredeck plunge pool), and styling that leans more modern and party-friendly while still offering serious passage capability.
The Fleming 85 takes a more traditional route into this territory. Layouts usually give you three or four guest cabins, all ensuite, with the owner cabin running full-beam amidships and crew tucked aft. It’s a comfortable six-guest boat in standard form, though a fourth cabin can push that higher. Performance is semi-displacement - twin MAN V12s around 1,550hp each deliver a top end close to 25 knots, but ease it back to displacement pace and she’ll cover about 3,500nm on 12,000 litres of fuel. You can have an open or enclosed flybridge, insulation is strong with double glazing, and the fit-out carries a level of refinement that appeals to long-range cruisers who still want a touch of formality in the way the boat feels.
