Lagoon 380 Bellevue 2010 vs Lagoon 42 2022 — Same Brand, Different Boat

The Lagoon 380 Bellevue 2010 vs Lagoon 42 2022 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Lagoon 42 2022 measures 42,0 feet overall (2022), giving it roughly 4,9 additional feet of deck space compared to the Lagoon 380 Bellevue 2010 at 37,1 feet (2010). Weight tells a clearer story for trailering families: the Lagoon 42 2022 tips the scales at 26 681 lbs — 10 675 lbs less than the Lagoon 380 Bellevue 2010 at 16 006 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 45 hp, the Lagoon 42 2022 has a 25-hp advantage over the Lagoon 380 Bellevue 2010's 20-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Lagoon 42 2022 carries 79 gallons versus 53 gallons in the Lagoon 380 Bellevue 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Lagoon 42 2022 is rated for 12 passengers, while the Lagoon 380 Bellevue 2010 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lagoon 42 2022 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Lagoon 42 2022 displaces 26 681 lbs — a 10 675-lb difference over the Lagoon 380 Bellevue 2010 at 16 006 lbs. That gap separates two entirely different categories of sailing: the heavier boat is built for offshore passage-making and load-carrying, while the lighter hull rewards performance sailing and easier handling in lighter air.

Both boats draw a similar depth — 3,1 ft and 4,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Lagoon 380 Bellevue 2010 uses fractional_rig_sloop rigging. For auxiliary power the Lagoon 42 2022 carries a 45-hp engine against 20 hp on the Lagoon 380 Bellevue 2010. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.

Bottom line: The Lagoon 42 2022 is the offshore and bluewater choice — at 26 681 lbs displacement and 42 ft it has the load capacity, range, and seakeeping for extended passages. The Lagoon 380 Bellevue 2010 at 16 006 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.

Lagoon 380 Bellevue 2010 vs Lagoon 42 2022 — Common Questions

Which is the larger boat — the Lagoon 380 Bellevue 2010 or the Lagoon 42 2022?
The Lagoon 42 2022 is the longer of the two at 42,0 feet overall. The Lagoon 380 Bellevue 2010 comes in at 37,1 feet, making it roughly 4,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Lagoon 380 Bellevue 2010 or the Lagoon 42 2022?
For trailering, the Lagoon 380 Bellevue 2010 has the edge at 16 006 lbs dry weight versus 26 681 lbs for the Lagoon 42 2022. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Lagoon 42 2022 is rated to a maximum of 45 hp, giving it the larger power ceiling. The Lagoon 380 Bellevue 2010 tops out at 20 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Lagoon 380 Bellevue 2010 is Coast Guard rated for 11 passengers, while the Lagoon 42 2022 is certified for 12. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat has the deeper draft — the Lagoon 380 Bellevue 2010 or the Lagoon 42 2022?
The Lagoon 42 2022 has the deeper draft at 4,1 ft, versus 3,1 ft for the Lagoon 380 Bellevue 2010. A deeper draft generally means better upwind performance and stability, but limits access to shallow anchorages and some marina berths. Always check the controlling depth of your home port and favourite cruising grounds before committing.
Is the Lagoon 380 Bellevue 2010 or the Lagoon 42 2022 better suited for offshore sailing?
For offshore work, displacement and construction are the primary indicators. The Lagoon 42 2022 at 26 681 lbs displacement is the heavier, more load-carrying design — generally better suited to extended passages where seakeeping and provisioning capacity matter most. The Lagoon 380 Bellevue 2010 at 16 006 lbs will typically be livelier and more responsive in lighter conditions.
Which boat is wider, and does it affect trailering?
The Lagoon 42 2022 measures 304" wide, compared to 258" for the Lagoon 380 Bellevue 2010. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Lagoon 380 Bellevue 2010 or the Lagoon 42 2022?
The Lagoon 42 2022 has the bigger tank at 79 gallons, versus 53 gallons on the Lagoon 380 Bellevue 2010. That 26-gallon difference translates to roughly 78–131 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Lagoon 380 Bellevue 2010 and Lagoon 42 2022 from the same manufacturer?
Yes — both the Lagoon 380 Bellevue 2010 and the Lagoon 42 2022 are built by Lagoon. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
