The Lagoon 380 S2 2017 vs Lagoon 40 2017 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.
On paper these two are close siblings in the size department — Lagoon 380 S2 2017 at 37,1 ft versus Lagoon 40 2017 at 38,6 ft. Weight tells a clearer story for trailering families: the Lagoon 380 S2 2017 tips the scales at 16 006 lbs — 5 121 lbs more than the Lagoon 40 2017 at 10 885 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.
Both boats share a closely matched power ceiling — 30 hp for the Lagoon 380 S2 2017 and 29 hp for the Lagoon 40 2017. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Lagoon 40 2017 carries 106 gallons versus 53 gallons in the Lagoon 380 S2 2017. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 11 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Displacement is where these two sailboats genuinely part ways. The Lagoon 380 S2 2017 displaces 16 006 lbs — a 5 121-lb difference over the Lagoon 40 2017 at 10 885 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 40 2017 draws 4,5 ft, compared to 3,1 ft for the Lagoon 380 S2 2017. That 1,4-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.

Bottom line: The Lagoon 380 S2 2017 is the offshore and bluewater choice — at 16 006 lbs displacement and 37 ft it has the load capacity, range, and seakeeping for extended passages. The Lagoon 40 2017 at 10 885 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
