The Lagoon 380 Bellevue 2010 vs Lagoon Seventy 7 2016 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 Seventy 7 2016 measures 76,3 feet overall (2016), giving it roughly 39,2 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 Seventy 7 2016 tips the scales at 135 937 lbs — 119 931 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 230 hp, the Lagoon Seventy 7 2016 has a 210-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 Seventy 7 2016 carries 740 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 Seventy 7 2016 is rated for 23 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 Seventy 7 2016 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Lagoon Seventy 7 2016 displaces 135 937 lbs — a 119 931-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.

Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Lagoon Seventy 7 2016 draws 6,3 ft, compared to 3,1 ft for the Lagoon 380 Bellevue 2010. That 3,2-foot difference affects which anchorages you can access, which haul-out facilities will take you, and how carefully you need to read the tide tables in shallower cruising grounds.

The Lagoon 380 Bellevue 2010 is rigged as a fractional_rig_sloop while the Lagoon Seventy 7 2016 carries Sloop rigging — a meaningful difference in sail handling complexity, upwind performance, and the size of crew you'll need to work the boat comfortably. Helm style differs too: the Lagoon 380 Bellevue 2010 uses a Single helm wheel versus a Twin helm wheels on the Lagoon Seventy 7 2016. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the Lagoon Seventy 7 2016 carries a 230-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.

For extended cruising, water capacity matters: the Lagoon Seventy 7 2016 carries 423 gallons versus 79 gallons on the Lagoon 380 Bellevue 2010 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
