The Boston Whaler 380 Realm is the larger Realm with quad-engine speed, full cabin and a yacht-like entertaining deck.
Within the Realm family, within Boston Whaler’s Realm family, the strongest reason to choose this size is how it balances physical footprint with the family’s mission. Quad-engine maintenance, 445 gallons of fuel and a 23,000-pound-class wet package make it materially more expensive than the 350
The 380 Realm should be cross-shopped with 350 Realm, 405 Conquest or 380 Outrage. On the 380 Realm, that comparison helps separate a genuine use-case advantage from the temptation to choose a larger or more expensive Whaler simply because it is available.
For a 380 Realm shopper, Boston Whaler’s foam-filled fiberglass construction is a major brand attribute, but a used boat still deserves a normal structural inspection. For a 380 Realm shopper, unsinkable construction does not make impact damage, poor repairs or neglected systems irrelevant.
For a 380 Realm shopper, the Realm mission is offshore cruising, entertaining, fishing and overnighting. A 380 Realm buyer whose normal weekend does not resemble that mission may be better served by another Whaler family.
At the dock, sit the expected crew in the 380 Realm. The 380 Realm capacity plate tells how many people are allowed; the real question is whether those people can move, store gear and use the boat comfortably.
The main compromise is clear: quad-engine maintenance, 445 gallons of fuel and a 23,000-pound-class wet package make it materially more expensive than the 350
Published factory figures. Confirm every dimension against the individual boat before you commit.
At 38′ 0″ overall, realm combines an offshore hull with express-cruiser mass, cabin structure and a large hardtop, making it a true marina-scale boat.
On the 380 Realm, 23 degrees of deadrise and 29″ of draft help explain where the hull sits between shallow-water access and offshore comfort. Within the Realm family, those dimensions should be interpreted with load and sea state in mind.
Beam is 11′ 8″. On the 380 Realm, that affects passenger space, dock fit and road transport. On the 380 Realm, boats wider than 8 feet 6 inches can require permit or professional-hauling considerations depending on jurisdiction.
Dry hull weight is 17,000 lbs. On the 380 Realm, lift and trailer decisions should add propulsion, fuel, batteries, freshwater, gear and installed options instead of sizing equipment from dry weight alone.
Inspect the 380 Realm from stem to transom in bright light. When evaluating the 380 Realm, look along chines, strakes, keel and transom corners for repair evidence, gelcoat mismatch or impact.
Within the Realm family, foam-filled construction makes professional repair quality especially important. At 38′ 0″ overall, a documented repair can be acceptable, while an unexplained patch or distorted running surface deserves more investigation.
When evaluating the 380 Realm, check engine mounting points, trim hardware, transducers and through-hulls. On the 380 Realm, high-output outboards place real load on the transom and poorly sealed accessory penetrations can create avoidable problems.
At 38′ 0″ overall, rails, cleats and rub rail can reveal docking history. For a 380 Realm shopper, heavy cosmetic damage around one corner often points to repeated contact rather than one harmless scratch.
When evaluating the 380 Realm, use the capacity plate and correct model-year factory specification to resolve conflicts with seller copy. At 38′ 0″ overall, online listings frequently inherit numbers from another year.
Configuration: Quad Mercury Verado outboards on common current configurations
The 380 Realm propulsion package is central to ownership. On the 380 Realm, engine count determines service cost, redundancy, steering complexity, battery requirements and much of the boat’s fuel budget.
Published maximum horsepower is 1,700 HP. Within the Realm family, that ceiling should not automatically become the target on a smaller Whaler if a more moderate package carries the normal crew comfortably.
Sea-trial the 380 Realm with realistic load in mind. For a 380 Realm shopper, adults, full fuel, fishing equipment and overnight gear can expose weak acceleration or poor propeller selection that an empty dealer run hides.
On the 380 Realm, on multi-engine versions, record every serial number and hour count. At 38′ 0″ overall, engines with different histories are not automatically a problem, but the difference should be understood and documented.
Test Mercury digital throttle, steering, joystick or SmartCraft functions fitted to the 380 Realm. For a 380 Realm shopper, a clean engine start is not enough if networked controls or engine data are intermittent.
When evaluating the 380 Realm, inspect propellers, skegs, gearcases, trim cylinders, steering hardware and mounts. For a 380 Realm shopper, underwater damage can create vibration and lost performance without leaving obvious cosmetic evidence above deck.
Ask for scheduled service records. Within the Realm family, gear oil, impellers, plugs, fluids, anodes and corrosion protection tell more about long-term care than a freshly detailed cowling.
At 38′ 0″ overall, during the sea trial, include idle maneuvering, acceleration, normal cruise and a broad loaded turn. On the 380 Realm, engine rpm and steering feel should remain consistent.
On the 380 Realm, if future repower is part of the ownership plan, verify maximum engine weight and transom rating before assuming the newest outboard is a direct replacement.
The 380 Realm carries a published fuel reference of 445 gallons. When evaluating the 380 Realm, verify the exact year because redesigned models can change tank volume while keeping the familiar name.
380 Realm fuel burn changes with engine package, sea state, trim, bottom condition and passenger load. Within the Realm family, a published performance test should be treated as one controlled configuration rather than a guarantee.
For the 380 Realm, identify a comfortable cruise and watch actual fuel flow on the engine display. Within the Realm family, build range around that speed and retain a meaningful reserve.
At 38′ 0″ overall, full fuel adds significant weight, especially on Conquest, Realm, Outrage and large Vantage boats. At 38′ 0″ overall, that can move acceleration and the most efficient cruise rpm.
Inspect fuel fills, vents, hoses, separators and accessible tank areas on a used 380 Realm. Within the Realm family, persistent odor should be investigated before closing.
For a 380 Realm shopper, a boat that has been stored for months may also need old fuel addressed. When evaluating the 380 Realm, ask how the seller handled stabilization and ethanol exposure.
Within the Realm family, annual fuel budget matters more than one test day. If the family cannot comfortably afford to run the 380 Realm as intended, the purchase will not deliver its promised use.
The 380 Realm should be judged at the speeds the owner expects to use most often. Within the Realm family, top speed is less important than clean planing, predictable steering, visibility and a comfortable cruise.
Within the Realm family, realm combines an offshore hull with express-cruiser mass, cabin structure and a large hardtop, making it a true marina-scale boat.
Practice an actual dock approach. At 38′ 0″ overall, windage, beam and engine count can make two Whalers of similar length behave very differently at idle.
For a 380 Realm shopper, at cruise, cross ordinary wakes and note pounding, spray, steering correction and windshield protection. The 380 Realm hull should inspire confidence without requiring constant correction.
When evaluating the 380 Realm, test acceleration with normal passenger weight in mind. Within the Realm family, coolers, rods, full fuel and cabin gear can expose an underpowered or poorly propped setup.
Use several trim settings. The 380 Realm should respond predictably without persistent porpoising, excessive bow rise or heavy steering.
When evaluating the 380 Realm, operate trim tabs or automated trim systems where fitted. Within the Realm family, intermittent control should be repaired before delivery.
Within the Realm family, listen for hardtop rattles, loose panels or propeller resonance. At 38′ 0″ overall, noise can reveal installation problems that a speed number never shows.
The 380 Realm is a express cruiser designed around large cockpit, cabin, head, prep center and dive access. On the 380 Realm, the deck should make that mission obvious before the buyer starts counting options.
Within the Realm family, walk the deck with the normal crew aboard. For a 380 Realm shopper, seat people forward and aft, then open the storage, fishboxes, livewells or cabin access they would use during a normal day.
Fishing equipment should be operated. When evaluating the 380 Realm, run livewell pumps, lift fishbox lids, inspect rod holders and verify drains rather than assuming clean equipment is functional.
Within the Realm family, family seating deserves the same attention. For a 380 Realm shopper, convertible backrests, removable cushions and tables should move easily enough that the family will actually use them.
The 380 Realm helm needs clear sightlines with passengers seated forward. Within the Realm family, windshields and hardtops should add weather protection without creating awkward blind spots.
On the 380 Realm, swim access is part of nearly every Whaler mission. When evaluating the 380 Realm, test ladders, transom doors, dive doors and engine clearance with the real propulsion package.
On the 380 Realm, storage should be dry and reachable. On the 380 Realm, a large total storage volume is less useful if every locker is trapped beneath occupied seating.
For a 380 Realm shopper, on Conquest and Realm, walk the transition below deck with the cockpit occupied. Within the Realm family, cabin access is more convincing when it does not interrupt everyone else.
If the 380 Realm layout feels awkward during a dockside test, compare 350 Realm, 405 Conquest or 380 Outrage instead of assuming ownership will make the compromise disappear.
260-quart under-seat cooler – On the 380 Realm, 260-quart under-seat cooler should be checked for condition and operation because it is part of the reason this configuration carries value over a simpler sistership.
On the 380 Realm, convertible v-berth cabin should be checked for condition and operation because it is part of the reason this configuration carries value over a simpler sistership.
On the 380 Realm, fully enclosed head should be checked for condition and operation because it is part of the reason this configuration carries value over a simpler sistership.
On the 380 Realm, cabin air conditioning should be checked for condition and operation because it is part of the reason this configuration carries value over a simpler sistership.
On the 380 Realm, cockpit prep center should be checked for condition and operation because it is part of the reason this configuration carries value over a simpler sistership.
On the 380 Realm, port-side dive door should be checked for condition and operation because it is part of the reason this configuration carries value over a simpler sistership.
On the 380 Realm, quad-outboard capability should be checked for condition and operation because it is part of the reason this configuration carries value over a simpler sistership.
On the 380 Realm, large simrad-integrated helm should be checked for condition and operation because it is part of the reason this configuration carries value over a simpler sistership.
The 380 Realm systems profile centers on air conditioning, shore power, freshwater, waste and large electronics networks. At 38′ 0″ overall, the inspection should reflect that mission rather than using one checklist for every Whaler.
Start with batteries and charging. At 38′ 0″ overall, engine banks, house banks and large audio or cabin loads should be identified and load-tested where practical.
When evaluating the 380 Realm, test installed Simrad, SmartCraft, VesselView or other electronics. When evaluating the 380 Realm, confirm GPS, sonar, engine data and network communication rather than simply verifying the screen powers on.
When evaluating the 380 Realm, run freshwater and raw-water systems for several minutes. For a 380 Realm shopper, pumps should build pressure and fittings should remain dry.
At 38′ 0″ overall, on boats with heads, test freshwater, waste pumps, tank gauges and ventilation. For a 380 Realm shopper, odor or slow pumps can signal deferred maintenance.
The 380 Realm belongs to marina and yacht-style systems ownership. Its 38′ 0″ length, 11′ 8″ beam and 17,000 lbs dry hull weight should shape the storage plan before delivery.
Add engines, 445 gallons of fuel capacity, batteries, freshwater where equipped, gear and trailer weight before choosing a tow vehicle or lift.
Within the Realm family, at a marina, verify slip width, shore power where relevant, finger-pier access and local Mercury service. For a 380 Realm shopper, large cabin boats need additional attention to freshwater and waste services.
Low-volume premium supply makes engine hours, auxiliary power, simrad electronics and cabin upkeep central to value.
Within the Realm family, propulsion is the first major adjustment. On the 380 Realm, engine count, horsepower, hours and service history can change value more than cosmetic color.
Electronics are next. Within the Realm family, newer integrated Simrad or Mercury systems can reduce refit cost, but older displays should not be valued at their original retail price.
On the 380 Realm, fishing options, tops, outriggers, trolling-motor systems and livewells matter most when the buyer will use them. At 38′ 0″ overall, expensive equipment that does not fit the mission is not automatically valuable.
On the 380 Realm, cabin condition deserves a separate adjustment on Conquest and Realm. On the 380 Realm, air conditioning, refrigeration, heads, shore power and freshwater systems can create meaningful deferred maintenance.
Within the Realm family, trailer condition matters heavily on Super Sport, Montauk and smaller Dauntless models because the trailer is part of the normal ownership workflow.
For a 380 Realm shopper, cosmetic condition should be separated from mechanical condition. On the 380 Realm, clean cushions cannot compensate for neglected engines or damaged running surfaces.
A documented 380 Realm can justify a premium over a cheaper sistership with uncertain history. At 38′ 0″ overall, strong total value matters more than the lowest advertised price.
Illustration only and not an offer of credit.
When evaluating the 380 Realm, run the payment on the real transaction and leave room for insurance, fuel, annual engine service, storage and the systems specific to this Realm model.
Illustration only and not an offer of credit. Your actual rate and term depend on credit profile, vessel age, loan amount and ownership structure.
The first cross-shop is 350 Realm, 405 Conquest or 380 Outrage.
The 380 Realm should win because the larger Realm with quad-engine speed, full cabin and a yacht-like entertaining deck fits the buyer better, not because one payment is lower.
When evaluating the 380 Realm, compare true size, hull mission, propulsion, passenger layout and storage before financing.
If that compromise would make the 380 Realm frustrating to own, the alternative deserves a closer look.
Start with hull identification and model year. Within the Realm family, Boston Whaler changes engines, fuel systems, electronics and options over time, so the exact year matters even when the model name stays familiar.
When evaluating the 380 Realm, verify seller specifications against the capacity plate and correct factory data. For this configuration, Boston Whaler publishes 38′ 0″ LOA, 11′ 8″ beam, 1,700 HP maximum horsepower and 445 gallons fuel capacity for the referenced configuration.
When evaluating the 380 Realm, inspect the hull in natural light. For a 380 Realm shopper, focus on chines, keel, transom corners and rub rail, then view the running surface from underneath.
When evaluating the 380 Realm, review engine hours and service history. On the 380 Realm, on multiple-engine boats, evaluate each engine separately and ask about any replacement or unusual hour difference.
When evaluating the 380 Realm, operate steering, trim and throttle under load. A short idle demonstration is not enough for a high-output 380 Realm.
When evaluating the 380 Realm, test pumps, livewells, fishbox drains, freshwater fittings and head systems fitted to the boat. On the 380 Realm, small failures are easier to negotiate before purchase.
When evaluating the 380 Realm, inspect electronics and networked engine data. For a 380 Realm shopper, a bright display does not prove radar, sonar, GPS, autopilot or engine gateways are all healthy.
When evaluating the 380 Realm, use every convertible seat, table, sunshade and hardtop feature. Within the Realm family, an expensive option only adds value when it works and the family actually wants it.
For a 380 Realm shopper, Boston Whaler currently lists the model in its active U.S. family.
Low-volume premium supply makes engine hours, auxiliary power, simrad electronics and cabin upkeep central to value.
Within the Realm family, if a trailer is included, inspect it as a separate asset. Within the Realm family, on marina boats, review lift history and bottom condition instead.
Finally, compare 350 Realm, 405 Conquest or 380 Outrage. The 380 Realm should remain the better fit after the technical inspection and ownership budget are understood.
Start your application with the actual 380 Realm details with model year, seller type, propulsion, engine hours where available and asking price.
At 38′ 0″ overall, year, propulsion, electronics, options, seller type and condition can move the transaction enough that complete boats should be compared instead of broad averages.
Boston Whaler publishes 38′ 0″ as the length reference used here. When evaluating the 380 Realm, verify the exact model year and completed rig when choosing a slip, trailer or storage building.
Boston Whaler publishes a persons capacity of 16 for this model. The capacity plate on the actual 380 Realm remains the final authority.
The published maximum is 1,700 HP. For a 380 Realm shopper, match the engine package to the exact model year and capacity plate before treating horsepower as a value upgrade.
The published fuel reference is 445 gallons. For a 380 Realm shopper, range should be estimated from the installed engine configuration, normal passenger load and a conservative reserve.
Trailering depends on the 11′ 8″ beam, 17,000 lbs dry hull weight and completed trailer package. For a 380 Realm shopper, wide models may need specialized transport, while smaller Montauk and Super Sport boats are designed around routine trailering.
When evaluating the 380 Realm, inspect the hull, transom, engine or engines, steering, pumps, electronics, upholstery, large cockpit, cabin, head, prep center and dive access, and the trailer or lift history. Within the Realm family, pay extra attention to equipment that defines this family.
Potentially. On the 380 Realm, model year, value, condition, purchase amount, seller type and borrower qualifications matter. On the 380 Realm, start your application with the actual details so financing reflects the exact boat.
