The Lagoon 400 2015 vs Lagoon 400 S2 2012 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 400 2015 at 39,4 ft versus Lagoon 400 S2 2012 at 39,4 ft. Weight tells a clearer story for trailering families: the Lagoon 400 S2 2012 tips the scales at 22 818 lbs — 287 lbs less than the Lagoon 400 2015 at 22 531 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 — 29 hp for the Lagoon 400 2015 and 29 hp for the Lagoon 400 S2 2012. 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. Both carry nearly identical fuel loads — 106 gal and 106 gal — so range won't be a tiebreaker here.
Both boats are rated for 12 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.
Both boats sit in a similar displacement bracket — 22 531 lbs for the Lagoon 400 2015 and 22 818 lbs for the Lagoon 400 S2 2012. Comparable displacement means broadly similar seakeeping behaviour and load capacity, though hull form and ballast ratio will still produce noticeably different sailing characteristics.
Both boats draw a similar depth — 4,0 ft and 4,0 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
