A flybridge, an enclosed wheelhouse with 360-degree glass and two Cummins V-drives on 42' 10" - drawn in two- and three-stateroom versions, cruising at 25 knots.

The 420 is Prestige's clearest thinking in the 40-foot segment, and the enclosed wheelhouse is the reason. Glass runs all the way around the helm, so the saloon, the galley and the driver share one bright space on a single level and nobody is shut away while the boat is moving. It makes the 420 a genuinely year-round boat in weather that empties an open helm. The Cummins QSB 6.7s on conventional shafts are about as serviceable as a marine diesel gets, and the build is consistent with what the yard does across the line.
This is a boat for an owner-operator with a family of four and a habit of going out for two or three nights. Two or three staterooms, one or two heads, 309 gallons of fuel and 87 to 112 gallons of water is an honest long-weekend package at 42 feet, and it is sized for exactly that. Look elsewhere if you need four cabins or crew accommodation — at 42' 10" neither exists here — and look elsewhere too if you want joystick pod handling as standard, because the 420 is a shaft boat and the pod package in this line starts with the 460.
Three things to settle before you commit. Which stateroom layout the hull has, and whether the master carries the walk-in closet or the second bathroom in that space. Whether the second water tank is fitted, because 87 gallons versus 112 decides a long weekend and it is not something you add later without effort. And observed fuel consumption at 25 knots, recorded in writing at sea trial.

The Prestige 420 is a 42' 10" flybridge yacht built to be run by the person who owns it. Beam is 13' 5", draft 3' 7", and light displacement 22,928 lbs, with a full-load figure of 32,711 lbs. Fuel is 309 US gallons and fresh water 87 US gallons, or 112 with the optional second tank. Those are the numbers that decide a slip, a bridge and a long weekend.
The layout is built around an enclosed wheelhouse with a 360-degree view of the water. It keeps the person driving inside the boat with everyone else instead of alone on a bridge deck, and it makes the 420 a genuinely year-round boat in weather that empties an open helm. Above it, the flybridge is sized as a second social deck rather than an overflow; aft, the cockpit opens into the wheelhouse and saloon.
Garroni Design and Prestige Engineering drew the hull, and Prestige rates the boat CE category B-10 / C-12. Power is a pair of Cummins QSB 6.7 V-drives, 380 hp each as standard or 425 hp as the option - conventional shaft-drive mechanicals that any yard can service and an owner can reach.
Prestige quotes two speeds for the 420 and both are useful. Cruising speed is 25 knots. Maximum is 31 knots, and Prestige states that figure at mid-load, so it is a working number rather than a light-boat number. Plan the day around 25.
Power is twin Cummins QSB 6.7 on V-drives, rated 380 hp each as standard with a 425 hp option. Both packages are conventional shafts. That matters for service life: parts and technicians for a QSB 6.7 exist in every boating market in the United States.
Draft is 3' 7", which opens up thin water on the Bahamas bank and in the shallower ICW cuts. Maximum air draft is 16' 1" - the figure to check against a boathouse, a fixed bridge or a marina approach before you commit to a berth. Light displacement is 22,928 lbs and full-load displacement 32,711 lbs; use the full-load figure when you are sizing a lift or a transport quote.
Fuel is 309 US gallons. Run the boat at your intended cruise rpm on sea trial, hold it there, and have the observed burn and the sea state recorded in writing. That is what tells you what 309 gallons is worth to you.
Prestige draws the 420 in two- and three-stateroom versions, and the choice is worth making deliberately rather than accepting whatever a used boat came with. The master is offered with a walk-in closet, or with a second bathroom in that space - which is why the head count reads one or two depending on the hull.
The wheelhouse is the room that defines the boat. Glass runs all the way around the helm, so the saloon, the galley and the driver share one bright space on a single level, and nobody is shut away while the boat is moving. Aft, the cockpit connects straight into that space; forward, the accommodation drops below.
Above, the flybridge carries the seating and the sunpads, with a hardtop offered over it. It is the deck the boat is bought for at anchor, and on 13' 5" of beam it is a genuine second living area rather than a bench and a wheel.
Fresh water is the tank to think about hardest. Standard is 87 US gallons; the optional second tank takes it to 112. Holding is 32 US gallons and the calorifier 11. If your habit is three or four nights out with a working transom shower, order the extra water at the desk - it is not something you can add later without effort.
The 420 sits in the F-Line, which Prestige runs as one line covering both the lettered new generation - F4.3, F4.9, F5.7, F6.7 - and the numbered boats: the 420, the 460, the 520 and the 590. It is the entry point to the whole range.
The closest comparison is inside Prestige's own line. The F4.3 is within an inch of the 420 on length and shares its 13' 5" beam, but it is the new-generation presentation: a Volvo D6-440 package, the OceanView Galley turned toward the cockpit, and a cruise quoted at 22 knots rather than 25. The 420 is the shaft-drive Cummins boat with the enclosed wheelhouse and the higher cruise. Go and see both on the same day, because they are the same size and they are not the same argument.
Outside the brand, the Galeon 420 FLY at 44' 11" and the Galeon 400 FLY at 40' 11" bracket it from the volume-and-features direction, and the Princess F45 at 47' 1" is the British benchmark a foot or two up. The Prestige answer to all of them is the wheelhouse: enclosed, glazed, and on the same level as the saloon.
This is a boat for an owner-operator with a family of four and a habit of going out for two or three nights. Two or three staterooms, one or two heads, 309 gallons of fuel and 87 to 112 gallons of water is an honest long-weekend package at 42 feet, and it is sized for exactly that.
Take it seriously if you want to run the boat from an enclosed, glazed helm on the same level as everyone else - that is the single thing the 420 does better than most of what it competes with, and it is what stretches the season at both ends. Take it seriously if 3' 7" of draft opens up water where you actually cruise. And take it seriously if you want conventional shafts and a Cummins diesel you can get serviced anywhere.
Look elsewhere if you need four cabins or crew accommodation; at 42' 10" neither exists here, and in this line those arrive further up. Look elsewhere too if you want joystick pod handling as standard - the 420 is a shaft boat, and the pod package in the range starts with the 460.
Three things to settle before you commit. Which stateroom layout the hull has and whether the master carries the closet or the second bathroom. Whether the second water tank is fitted. And observed fuel consumption at 25 knots, recorded in writing at sea trial.
Two or three staterooms. Prestige draws the boat both ways, and the master is offered either with a walk-in closet or with a second bathroom in that space, which is why the head count reads one or two depending on the hull. Accommodation is four. Settle which layout a particular boat carries before anything else.
Prestige publishes a 25-knot cruising speed and a 31-knot maximum, and states that maximum at mid-load rather than light, so it is a working figure. Power is twin Cummins QSB 6.7 V-drives at 380 hp each, with a 425 hp option. Plan the day around 25 knots, and have observed fuel consumption at that speed recorded in writing at the sea trial.
Shafts. The 420 runs twin Cummins QSB 6.7 diesels on V-drives, a conventional arrangement with parts and technicians available in every boating market in the United States. Joystick pod handling starts higher in the F-Line, at the 460. If you have a settled view on drivetrain servicing over ten years of ownership, that is the fork in the line.
Three feet seven inches, which on a 42' 10" boat opens up the Bahamas bank and the shallower Intracoastal cuts. The number to check against a berth is the other one: maximum air draft is 16' 1", so measure your boathouse, your fixed bridge and your marina approach before you commit to a slip.
