Captain's Report

Contents of Report

Boston Whaler 380 Realm running

The Boston Whaler 380 Realm measures 38’ (11.58 m) with an 11’8” (3.56 m) beam and comes with quad Mercury outboards up to a total of 1400-hp.

Mission Statement

Boston Whaler takes its hybrid-boat Realm series a step bigger with the new 380. This boat has a layout that places a priority on socializing, entertaining, cruising, and comfort, but can still easily become a serious offshore battlewagon if she is optioned out that way. Belowdecks, she has accommodations for weekending. The dinette converts easily to a V-berth, there’s a smaller galley and the head has a dedicated shower faucet and full-length mirror.

Boston Whaler 380 Realm deckplan

Whether passengers want to go after big game in the open aft cockpit or soak up the rays in the bow, the 380 Realm can accommodate both.

Features Inspection

The Cockpit

Two steps down on the starboard side and an inward-opening door to port, make it easy to board the 380 Realm from either side. The cockpit has 45-sq. ft. (4.2 sq. m) of wide-open space for dancing to tunes from the Fusion Apollo stereo or fight big game. One thing we noticed right away on this boat is that Boston Whaler stores accessories for specific functions near the location for their intended use.

For example, the boarding ladder that clips in place when the aforementioned inward-opening door is opened stores in the base of the fold-out bench seat. Having it nearby makes perfect sense. There are in-deck insulated fishboxes and at the forward end of the cockpit is seating. The bottom cushion for this seat is hinged and opens to reveal a 260-quart (246 L) cooler. There’s also a smaller clear hatch that can be opened to grab a quick drink.

Boston Whaler 380 Realm cockpit

The 380 Realm’s cockpit is designed with plenty of open space to be available when it’s needed. This wide-angle shot shows the open port side door.

Boston Whaler 380 Realm boarding

Twin steps in the starboard bulwark facilitate boarding from the docks.

Boston Whaler 380 Realm hull door

The door in the aft port hullside opens inward on heavy-duty hinges.

Boston Whaler 380 Realm door handle

This handle flips around to help swimmers/drivers when they’re reboarding. The ladder clips into the stainless-steel bracket in the opening.

Boston Whaler 380 Realm ladder

The ladder stores close to the boarding door in the base of the fold-out bench seat.

Boston Whaler 380 Realm bench seat

Here, our test captain demonstrates how easily the bench can be lowered to increase seating capacity.

Boston Whaler 380 Realm mezzanine

The Mezzanine seat has space for two people to sit and keep an eye on lines when trolling or when kids are bouncing around the wakes on a tube.

Boston Whaler 380 Realm cooler

There’s a large cooler in the base of the aft-facing mezzanine seat that also has a flip-out footrest in the base.

Boston Whaler 380 Realm cooler hatch

This smart hatch in the cooler is clear to make it easy to first find the desired drink and then grab it.

Center Seating

The backrest for the seat above the cockpit cooler can be adjusted for forward- or aft-facing travel. Rotate the spin-able captain’s chair at the helm to create a booth-style seating where a table can be installed. Again, there are flip-down footrests. Overhead, the hardtop provides shade and our test boat had the optional power sunroof and a rack for gear.

Boston Whaler 380 Realm cockpit lounge

Position the backrest for the aft cockpit lounge for forward facing travel and rotate the captain’s chair for a social setting.

Boston Whaler 380 Realm table

Notice that the table mounts on the base of the seat and not in the deck, which is better for passengers to find a comfortable place for their feet.

Boston Whaler 380 Realm foot rests

Flip-down footrests enhance passenger comfort for the center seating area.

Boston Whaler 380 Realm sun roof

The 380 Realm is the first boat from Boston Whaler with a power sunroof.

Boston Whaler 380 Realm board rack

A rack for stand-up paddleboards on top of the hardtop is also new for 2019.

On Deck Galley (“Summer Kitchen”)

Across from the center seating area is the 380 Realm’s prep center which is a cockpit galley with a Corian countertop. Forward, a section of the countertop swivels to reveal the electric grill and provide a food-prep area. There’s also a removable hatch over the sink that stores in a drawer just below. A wastebasket is outboard of the sink with beverage holders and at food level is a refrigerator drawer.

Boston Whaler provides additional storage in drawers and there’s even a dedicated spot for a 5-gallon (19-L) bucket. Ahead is a single captain’s chair that swivels so the companion can join in on the fun.

Boston Whaler 380 Realm prep center

The Corian countertop and accent lighting give the prep center an upscale feel.

Boston Whaler 380 Realm grill

The section of the countertop above the electric grill cleverly swivels to provide a prep area and just outboard is the wastebasket.

Boston Whaler 380 Realm refrigerator

The refrigerated drawer is a good choice for a cockpit application because there’s less chance of it accidentally opening.

The Helm

Most Important. With a hardtop, side windows for spray and wind protection, plus a high windshield that reaches the hardtop, the 380 Realm’s helm is cozy and protected. This is, perhaps, the most important aspect of the boat as it means the boat can be operated in nearly any condition. With the addition of cruising canvas, the 380 Realm becomes a three-season boat.

Forward to starboard, the 380 Realm’s helm has space for optional triple 16” (40.6 cm) Raymarine multifunction displays. Above on top of the panel, the compass is centered in line with the steering wheel. There is a row of accessory switches above the MFDs with air conditioning vents integrated into the dash.

We like the glove box down low on the port side of the dash. Next to that is the Fusion Apollo stereo. To starboard are the trim controls and the 9” (22.86 cm) Mercury VesselView displays. Among the features on our test boat are the cruise-assist speed control, bow hook, sky hook, and drift hook. The digital shift and throttle controls are positioned in a dedicated section of the panel and outboard is the joystick for the Mercury system.

Outboard to starboard is a dedicated panel for all the circuit breakers. Kudos to Boston Whaler for an intelligent location for this. Two other options to consider are Mercury’s Active Trim and the Theft Deterrent System Remote connectivity system known as Whaler Watch.

Boston Whaler 380 Realm helm

The 380 Realm’s helm has a straightforward layout with all information provided on the three optional multifunction displays.

Mercury’s 9” VesselView screen monitors the health of all four motors.

Boston Whaler 380 Realm controls

The digital controls offer a variety of functions for the captain and the Mercury joystick is outboard to starboard.

Boston Whaler 380 Realm breaker panel

The circuit breakers and ignition switches are in a dedicated panel outboard to starboard. This is smart because it keeps the dash panel from feeling cluttered and it adds to the security of the vessel.

The Bow

A passageway to port leads to the 380 Realm’s bow. Storage compartments line the outboard bulwarks with hatches that tilt inward. A door and window that close off the walkway open on gas struts. Just ahead of the door in the port gunwale, there’s a 70-quart (66.26-L) cooler with a hatch that opens on a gas strut. The bow has seating that wraps around an optional adjustable-height table that can be lowered and topped with a filler cushion to create a protected playpen or sunlounging area.

The bottom cushions for the bow lounges lift up to provide access to storage. The backrests for the forward-facing seats have flip-down armrests that have integrated drinkholders. That makes a total of 39 beverage holders on the boat. An optional shade can be erected easily to provide sun protection. In the foredeck, the anchor locker hatch opens on a stainless-steel strut to reveal the windlass, rode cleat, and chain locker.

Boston Whaler 380 Realm bow passage

With the bulwark compartments closed, there’s easy passage to the 380 Realm’s bow and notice the grabrail.

Boston Whaler 380 Realm hatches

The hatches open on retainers that keep them from going too far and they close on rubber gaskets that keep out water and prevent rattling.

Boston Whaler 380 Realm forward cooler

To keep the bow passengers from having to go all the way aft for a cold drink, there’s a cooler in the port passageway.

Boston Whaler 380 Realm bow table

The bow table has a custom graphic and a top-quality finish. Also, notice how robust the base is.

Boston Whaler 380 Realm bow

Lower the table and drop in the filler cushion to create a spacious lounge with a wraparound bolster and grabrail.

Boston Whaler 380 Realm armrests

Flip-down armrests have integrated cupholders and there’s small-item storage in the gunwale starboard.

Boston Whaler 380 Realm bow storage

All of the bottom cushions in the bow open on pneumatic struts, making it easier for passengers to retrieve gear.

Boston Whaler 380 Realm shade

The shade goes up easily on stainless-steel stanchions to provide respite from the sun.

Boston Whaler 380 Realm anchor locker

The anchor locker is complete with a windlass, a remote control for the accessory, and access to the rode locker.

The Cabin

Heading belowdecks, the 380 Realm’s cabin has a V-shaped seating area forward that converts to a berth that could sleep a couple. An added touch for comfort, the table slides forward to make it easier to enter the seating area. The small galley has a microwave oven, a sink and refrigerator, and plenty of storage. A tablet that comes with the boat can be used to monitor and control on board functions and for entertainment, there’s a 24” (61cm) TV above the berth. It’s flanked by the electrical distribution panels. A private head has standup headroom with a separate shower faucet instead of pulling out the sink. There’s also a full-length mirror on the inside of the entry door.

Boston Whaler 380 Realm dinette

The dinette table can be lowered to convert the cabin area into a V-berth for sleeping. Again, notice how substantial the base is.

To make it easier to sit down, the table slides forward.

Boston Whaler 380 Realm galley

The compact galley has a sink and microwave oven. Notice the port outboard and skylight overhead that let in natural light.

Boston Whaler 380 Realm tablet

Boston Whaler provides a table with the boat that lets the user control on board systems from the cabin.

Boston Whaler 380 Realm tv

Electrical distribution panels flank the TV above the galley.

Boston Whaler 380 Realm toilet

The toilet is raised off the head sole and notice the air conditioning duct just aft that will make it easier to rid the area of steam.

Fishing. If fishing is on the list of a day’s activities, there are rod holders across the transom as well as fresh- and raw-water washdowns in the aft bulwarks. Our test boat was pre-rigged for electric reels and there are insulated fishboxes on both sides of the cockpit. Freezer plates can be added to the starboard fishbox to keep things chilled.

Boston Whaler 380 Realm rod holders

Above, there are rod holders in the deck and the anglers can lean against the bolster that rings the cockpit. The four outlets to the left are pre-rigged for electric reels and the two above the speaker to starboard are for the shorepower cords.

Boston Whaler 380 Realm raw wash down

The raw-water washdown will make it easy to clean up the cockpit after a busy day on the water. We wonder how smart it was to position a stereo speaker right below it.

Boston Whaler 380 Realm fishbox

There are twin insulated fishboxes outboard on each side of the cockpit and the hatches open on gas struts so crew members can use two hands when adding ice or retrieving the day’s catch.

On Board Systems. A single large hatch in the cockpit deck provides access to virtually all of the 380 Realm’s on-board mechanical systems, including the optional 12 kW diesel generator, the Seakeeper SK6 gyroscopic stabilizer, the macerator pumps for the fishboxes, the batteries and 40-amp charger, the power steering pump, and the fire suppression system. In the center are the strainers for the air conditioning and generator as well as the bilge pumps.

Boston Whaler 380 Realm access

This large hatch in the center of the cockpit deck provides access to mechanical accessories and has dedicated storage for the boat’s two tables. The diesel generator is under the blue canvas cover.

Boston Whaler 380 Realm seakeeper

Seakeeper gyroscopic ride stabilizers are becoming some of the most sought-after equipment on boats that head offshore.

Boston Whaler 380 Realm batteries

Boston Whaler puts the batteries in a position where they can be checked or replaced without a mechanic risking the health of his back.

Boston Whaler 380 Realm sea keepers

The strainers and seacocks are placed where they can be reached and checked quickly. That’s a sign of a veteran boat builder.


The Numbers. The 380 Realm measures 38’ (11.58 m) with an 11’8” (3.56 m) beam. Empty weight is listed at 17,000 lbs. (7,711 kg) and with 102 gallons (386 L) of fuel, three people and test gear on board, our estimated weight was 20,921 lbs. (9,490 kg). Our test boat was powered by four 350-hp Mercury Verado outboards spinning 16” x 18” Mercury Enertia Eco propellers.

Top Speed. Running in 2’ (.61 m) seas and 15-mph winds, we hit a top speed of 53.5 mph at 5700 rpm. In its own tests in calm water, Boston Whaler says it hit 56.8 mph, and we certainly believe that given the adverse conditions we tested in.

Best cruise came at 4000 rpm, where we recorded 34.8 mph and 45.1 gph, which translated into 0.8 mpg and a range of 309 statute miles with 10% of the boat’s 445-gallon (1,685 L) fuel capacity in reserve.

In acceleration tests, the boat planed in 5.7 seconds and ran to 20 mph in 6.2 seconds and to 30 in 10.4 seconds. At 600 rpm, she ran 4.1 mph and at 1000 rpm, we recorded 5.9 mph.

Boston Whaler 380 Realm running

Even in less-than-ideal conditions, the 380 Realm topped double-nickel speeds and at optimum cruise, she has a range of more than 300 statute miles.


It’s rare that we get to test a boat’s ability to handle rough conditions and the 380 Realm lives up to her pedigree with an exceptional ride. This is in no small part due to her 23-degree deadrise at the transom, which is one of the greatest in class. Most builders compromise at 21 degrees in order to have a higher top speed. Boston Whaler has clearly chosen the route to a better ride since it knows top speed is not important.

She skipped effortlessly across the wavetops and pushed spray low and wide, keeping the deck bone dry. Even when we put the boat in the worst scenarios, she refused to get the topsides wet. In following seas, she showed the best handling characteristics, and around the docks, the joystick made maneuvering the boat a non-issue.

Boston Whaler 380 Realm running

With a deep-V design that has 23 degrees of deadrise at the stern, the 380 Realm cut through waves with ease.


Boston Whaler has one of the best construction systems in class. The company has pioneered the concept of building boats that don’t sink and will float level if swamped. This is quite an accomplishment. The company fills all voids between the hull and liner with foam. Not only does that keep the boat from sinking and floating level if swamped, but it also makes the boat quieter when running, and gives the boat a solid feel.

Essentially the hull, inside substructure, and the deck become one unit, rather than a series of parts. That process gives the hull great integrity.

Warranty. Ten-year structural hull, three years on components manufactured or installed by Boston Whaler, one year on upholstered items, canvas, teak and powder coating.

Options to Consider Not Mentioned in Report

  • 300’ (91.4 m) of anchor chain
  • Prep center with livewell
  • Raymarine autopilot
  • Canvas cover package


With the Realm series and particularly with the 380, Boston Whaler has created a hybrid of several concepts that makes the boat designed for the times. Her helm and bridge deck are protected by a high windshield, hardtop and glass side curtains that will keep everyone cozy. By having a large bow with a table for entertaining, seats that are versatile under the hardtop, several entertainment venues can be created to fit the occasion. Her cabin makes her a weekender. Her cockpit makes her a fishing boat.

In one boat she is a little express cruiser, bowrider, and fishboat all rolled into one.

With a 23-degree deadrise at the transom, she is one of the deepest deep-Vs on the market. That means that her ride should be among the very best in class.

And, like all Boston Whalers, she will not sink.
