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.
