A mid-fifties flybridge that lets you decide what it is: order the aft volume as a crew cabin and the 520 FLY is a boat run for you, order the tender garage and it is yours to drive - with a full-beam master behind its own private door either way.
Part of the Galeon FLY series — see how owners step up through the lineup.


The 520 FLY is 56' 5" overall on a 48' 4" hull, and the difference is mostly a bathing platform that pays you back every single time you anchor. Book your dockage on the overall figure, enjoy the platform, and you have made one of the better trades in this size range - the interior volume of a boat in the low fifties with the aft deck of something bigger.
The decision that actually matters here is aft. The same volume is either an optional crew cabin or a tender garage, and I have rarely seen two more different boats come out of one hull. Order the crew cabin and you have something a captain can run and look after, which changes what your whole season looks like. Order the garage and you keep the cockpit clear, the toys out of the way, and the boat firmly yours to drive. Neither is the right answer in general; there is a right answer for you, and it is worth an hour of conversation before you configure anything else. While you are aboard, go and look at the full-beam master. A private entrance to an owner's cabin at this length is not common, and it is the thing owners tell me they notice on the second weekend rather than the first.
Where I will slow you down is the paperwork. The quoted weight of 57,757 lbs is the weight with base engines, so the weight you size a lift from should be tied to the engine package on your own order sheet, not to a brochure line. And settle the draft: it is quoted as deep as 5' 5", and I would rather tell you that now than let you find it at survey. Get the draft, the beam, the base engine and the rigged weight for your build confirmed in writing - and then enjoy the boat, because the boat itself is a good one.

The Galeon 520 FLY is the newest boat in the middle of Galeon's flybridge range, and the builder is direct about where it came from: it builds on one of the yard's bestselling flybridge platforms, refined rather than redrawn, with updated ergonomics and a more contemporary interior. Galeon sells it into the 50 to 55 foot flybridge segment, at 56' 5" length overall on a 48' 4" hull - book dockage on the overall figure.
Below deck the layout is three cabins for six guests. The full-beam master sits amidships with a private entrance and an en-suite, an arrangement that usually appears one size up. Forward is a VIP with generous glazing and natural light. The third guest cabin carries a sliding bed system that converts between a double and twins. Aft, Galeon offers the choice that defines this boat: an optional crew cabin, or a tender garage in the same volume. Three en-suites and a day head are listed.
Capacities are 476 gallons of fuel in two tanks, 172 gallons of fresh water, 82 gallons of grey and 66 gallons of black. Light-craft mass with base engines is 57,757 lbs, the maximum engine rating is D11-725 at 2 x 725 hp, and top speed is up to 30 knots. The boat is CE Category B with a crew limit of 14.
Galeon quotes a top speed of up to 30 knots for the 520 FLY. The numbers worth planning a passage on are the ones you take off a rigged boat with a fuel-flow reading, at your intended cruise rpm.
The engine option is the D11-725, a maximum of 2 x 725 hp. The quoted light-craft mass of 57,757 lbs is the weight with base engines, so tie the two together on your own order: get the base engine package and the rigged weight of your build in writing before you size a lift.
Draft is quoted three ways on this model: 3' 5", with a second figure of 5' 5", and 2' 11" for the hull without propellers. Plan to the deeper end of that spread, and settle the figure in writing before you commit to a shallow home berth.
Beam carries a smaller spread of the same shape - 15' 3" underway and 21' 10" with the balconies open, against a hull beam of 15' 1" and an overall beam of 22' 0". Inches rather than feet, but if your slip or your lift is tight, get the figure for your build confirmed.
Galeon runs a 3D configurator and a virtual experience for the 520 FLY. Both are worth an hour for understanding the layout, and neither replaces a confirmed specification for your hull.
Galeon offers the 520 FLY interior two ways: a designer choice version, or the Mediterranean package developed with the design studio Insitu & Partners. The Mediterranean package runs five colour schemes - Ivory, Pearl, Ocean, Amber and Terra - built on high-gloss lacquered surfaces with premium fabrics and integrated lighting. It is a genuine fork rather than a trim level, so make the decision at the order desk with the samples in front of you.
The main deck is open-plan. Galley and dining share one space with the saloon, large windows run both sides, and the flow to the cockpit is direct. Above it, the flybridge is arranged around a single large sofa and is designed as the boat's primary social zone rather than an overflow area. Galeon's Beach Mode transformation opens the aft end of the main deck to sea level as a terrace-style space, and with the balconies down the beam goes from 15' 3" to 21' 10".
Below, six guests in three cabins. The amidships master is full beam with a private entrance and its own bathroom - the feature to go and physically look at, because a separate entrance to an owner's cabin is unusual at this length and it changes how the boat feels with guests aboard. The forward VIP takes the natural light. The third cabin's sliding bed system means one boat covers a couple travelling with adult friends and a family travelling with children, without a refit.
Two numbers set the practical limits: 172 gallons of fresh water and a 66-gallon black tank, on a boat rated for 14 people. Those are the figures to plan showers and pump-outs around - and note that 172 gallons is the same fresh-water capacity Galeon gives the 480 FLY, eight feet shorter.
The 520 FLY sits at the centre of Galeon's flybridge line, and it is the model where the range changes character. Below it, the 480 FLY is 48' 5" with three cabins, two heads and no crew space at all. Above it, the 560 FLY is 57' 7" with three cabins plus a dedicated twin crew cabin as part of the arrangement. The 520 is the boat that lets you decide: order the optional crew cabin and you have a boat that can be run for you; order the tender garage instead and you have a boat you run yourself with somewhere proper to put the dinghy.
At 56' 5" overall on a 48' 4" hull, it gives you the interior volume of a boat in the low fifties with a bathing platform that earns its keep every time you anchor.
Against the wider market, a mid-fifties flybridge with a full-beam master and an owner-operable helm is a competitive place to be - the Princess F55, the Prestige F5.7 and Azimut's Fly range are the boats buyers usually put beside it. What tends to decide it is the aft space: whether you want crew quarters, a garage, or the open transom-and-balcony arrangement Galeon has made its signature.
One practical note. Galeon points you at an enquiry and a configurator rather than at inventory, so a new 520 FLY is a build slot rather than a boat on a dock.
The 520 FLY fits the owner who wants a mid-fifties flybridge and has a firm view about what goes in the back of it. That is the real decision on this boat. The same volume aft becomes either a crew cabin - which turns the 520 into a boat somebody else can run and maintain for you - or a tender garage, which keeps the transom clear and the toys out of the cockpit. Galeon will build it either way, and the two boats live very different lives.
It fits an owner who values a private master. The amidships suite is full beam with its own entrance and bathroom, so guests are not walking past your door to reach a head, and the third cabin's sliding beds convert between a double and twins without a refit. Three heads for a six-guest layout is generous at this length.
It fits the buyer who spends real time at anchor. Beach Mode opens the aft main deck to sea level as a terrace, and with the balconies down the beam goes from 15' 3" to 21' 10". If you have watched a Galeon do that in a marina and thought about your own weekends, that is the feature you are buying.
Measure your slip against the full 56' 5" length overall, and settle the draft in writing before you commit to a shallow home berth - it is quoted as deep as 5' 5". And make the order desk do its paperwork: the base engine package and the rigged weight for your build, confirmed in writing, before you sign.
You get one or the other, and it is the real decision on this boat. The accommodation is three cabins plus one — an optional crew cabin, or a tender garage built into the same volume aft. Galeon calls the cabin an optional skipper's cabin and frames it as flexibility for longer passages or crew use. Order the cabin and you have a boat somebody else can run and maintain for you; order the garage instead and you keep the transom clear and the toys out of the cockpit. The two boats live very different lives.
The rest of the accommodation is the same either way. Three heads — one more than the 480 FLY below it. The full-beam master sits amidships with a separate private entrance and its own en-suite, the VIP is forward, and the third guest cabin has a sliding bed system that converts between a double and twin berths. That is six berths below deck. The 14 guests Galeon lists is the crew limit under CE category B — day capacity, not berths.
A new superstructure on a proven hull, and Galeon says so directly: the 520 FLY is built on the hull platform of its bestselling predecessor, inheriting that boat's performance, stability and handling, with an updated superstructure, a refined layout, improved onboard ergonomics and a more contemporary interior. The predecessor is out of production.
What that means when you shop: the hull is not an unknown quantity - and it is still worth asking the yard what carried over and what was redrawn rather than assuming. Two decisions are genuinely new and both are made at the order desk. The first is the volume aft, which becomes either a crew cabin or a tender garage. The second is the interior, offered either as a designer choice version or as the Mediterranean package developed with the design studio Insitu & Partners, which runs five themes — Ivory, Pearl, Ocean, Amber and Terra — on high-gloss lacquered surfaces. That is a fork rather than a trim level, so make it with the samples in front of you.
56' 5" overall, on a hull that measures 48' 4" - Galeon publishes both figures, and the difference is bathing platform and pulpit. Book the slip on 56' 5", because dockage is billed on length overall, and confirm the marina measures bow-to-stern with the platform included.
Width is the second question: beam is 15' 3" underway, and the Beach Mode balconies take the boat to 21' 10" when they drop, so whether you need the wider berth depends on whether you intend to open the boat at the dock. Draft is quoted at 3' 5", with a second figure of 5' 5"; plan on the deeper one.
Up to 30 knots, on a maximum of 2 x 725 hp - the D11-725 rating. Those are Galeon's quoted figures, and the 30 knots is a builder maximum rather than a test result, so ask for observed speed and consumption at your intended cruise rpm in writing before you plan a passage on it.
The weight deserves the same discipline. The 520 FLY's light-craft mass is 57,757 lbs, defined as the weight with base engines, so tie the figure to the engine package on your own order sheet: get the base engine and the rigged weight for your build confirmed in writing before you size a lift. Maximum load is listed at 4,409 lbs.
