The enclosed-helm line — express cruisers on Outrage hulls, at 35'6" and 38'0"
The season you actually get is decided by weather, and an open boat shortens it. Realm is the answer to that. Two express cruisers — the 35'6" 350 Realm and the 38'0" 380 Realm — built on Boston Whaler's Outrage hulls but with the helm enclosed and climate controlled, so a cold morning or a wet afternoon stops being a reason to leave the boat on the lift. Both carry one cabin and one head below.
The clearest way to understand this line is the 380. It uses the same 38'0" x 11'8" hull as the 380 Outrage; what changes is everything above the deck. The enclosed helm and the structure that supports it put the 380 Realm at 17,000 lbs dry against the Outrage's 14,500, and it sits deeper — 29 inches of draft against 23.5. You are spending 2,500 lbs and five and a half inches of water, and what you get back is a boat you will still use in February. That is the trade, stated plainly.
Against the Conquest line, Realm reads sportier. Conquest builds a cabin cruiser around a fishing platform and gives a family somewhere to sleep; Realm keeps the express layout, one cabin and one head, and spends the rest on the helm and the cockpit. The 350 Realm carries 385 gallons of fuel, 45 gallons of water and takes 750–1,275 hp for 14 people. The 380 Realm carries 445 gallons plus 20 gallons of diesel when equipped, 55 gallons of water, and takes 1,200–1,700 hp for 16.

Moving Up the Realm Series
There are only two boats here, so the decision is unusually clean — but the gap between them is wider than the 2'6" of length suggests. The 350 Realm is 35'6" on a 10'10" beam, 13,600 lbs dry and 18,830 lbs loaded, with 385 gallons of fuel, 45 gallons of fresh water, 10 gallons of waste and a 24.5" draft. It is rated 750 to 1,275 hp and for 14 people. It is also a boat one person can bring into a slip without a conversation about it first.
The 380 Realm changes scale in every direction. Beam goes to 11'8", fuel to 445 gallons with an extra 20 gallons of diesel when the boat is equipped for it, water to 55 gallons, capacity to 16 people. Rated power starts almost where the 350 stops — a 1,200 hp minimum against the 350's 1,275 hp maximum — and runs to 1,700. Dry weight is 17,000 lbs, and 23,500 lbs with quad engines and full fluids aboard.
What that step buys is mass and reach: 60 more gallons of fuel, 10 more gallons of water, two more seats, and enough horsepower ceiling to carry the extra weight without straining for it. What it costs is draft — 29 inches against 24.5 — and the ease of handling a smaller boat alone. Both models have one cabin and one head, so this is not a step that buys accommodation. Buy the 350 if you run shallow water and dock without help. Buy the 380 when the days are longer and the water is rougher.
Our Take
I would take the 350 Realm, and the reason is the 24.5-inch draft. It is the shallowest enclosed-helm boat Boston Whaler builds, which means shelter over your head without giving up the water most enclosed-helm boats cannot reach. At 13,600 lbs dry with 385 gallons aboard it is light enough that 1,275 horsepower is a genuinely serious number rather than the minimum required to move the thing.
Where I will argue against myself: the 380 Realm is the better rough-water boat and I would not talk anyone out of one. It is 3,400 lbs heavier dry, ten inches wider in the beam, and you feel both in a head sea. If most of your season is spent well offshore rather than in skinny water, take the bigger boat and stop reading.

Frequently Asked Questions
Does the Boston Whaler Realm have a cabin and a head?
Yes. Both Realm models have one cabin and one head below deck — the 350 Realm and the 380 Realm are the same in that respect. This is a two-boat line, so accommodation is not what separates them. Size, fuel, capacity and power rating are.
Because the cabin count does not change, the step from the 350 to the 380 buys fuel, water, seats and horsepower rather than berths: 445 gallons against 385, 55 gallons of water against 45, 16 people against 14, and a 1,700 hp ceiling against 1,275. If you need more sleeping space than a single cabin, the Conquest line is the part of the Boston Whaler range built for that — the 405 Conquest has a private master stateroom plus a mid-berth for three.
Is the 350 Realm or the 380 Realm better for shallow water?
The 350 Realm. It draws 24.5 inches against the 380 Realm's 29 inches, and at 13,600 lbs dry and 18,830 lbs loaded it is the lighter boat by a clear margin — the 380 Realm is 17,000 lbs dry and 23,500 lbs loaded with quad engines and full fluids. Four and a half inches of draft decides a lot of backcountry.
The 350 is also the narrower boat, 10'10" of beam against 11'8", which matters in tight channels and alongside a crowded fuel dock. The trade is offshore comfort: the 380's extra mass and beam work in your favour once you are in a head sea. If your season is mostly skinny water and day runs, the 350 is the better tool for it.
What is a Boston Whaler Realm?
The Realm is Boston Whaler's express cruiser line: two models, the 35'6" 350 Realm and the 38'0" 380 Realm, both built with an enclosed, climate-controlled helm instead of an open center console. Each has one cabin and one head below deck, and they are rated for 14 and 16 people respectively.
The line sits between the open Outrage boats and the cabin-cruiser Conquest models. You keep the express layout and a working cockpit, and you add shelter — which in practice means a longer usable season in cold or wet weather. Fuel capacity is 385 gallons on the 350 Realm and 445 gallons on the 380 Realm, with an additional 20 gallons of diesel on the 380 when it is equipped for it.
How much fuel does a Boston Whaler 380 Realm hold?
The 380 Realm holds 445 gallons of fuel, plus 20 gallons of diesel when the boat is equipped with the diesel option. Fresh water is 55 gallons and waste is 10 gallons. That is 60 more gallons of fuel than the 350 Realm, which carries 385 gallons alongside 45 gallons of fresh water.
How far that takes you depends on the engine package. The 380 Realm is rated from 1,200 to 1,700 horsepower, and a quad-engine boat with full fluids weighs 23,500 lbs against 17,000 lbs dry — so the same tank produces very different range at the two ends of that rating. Boston Whaler does not publish speed or fuel-burn figures, so plan your range from a sea trial with the engines you actually intend to buy.
