Design & Comfort Differences
The two boats feel meaningfully different on board, even within the same nominal size class. Three specific differences worth knowing:
- Saloon and deck space. The Lagoon 40 has a classic enclosed saloon with a wide aft deck; the Lagoon 46 offers a more conventional enclosed saloon.
- Cabin configuration. Both boats offer 3 (Lagoon 40) vs 4 (Lagoon 46) guest cabins. If you need 4 equal cabins for a multi-couple charter, the Lagoon 46 is the better fit. Otherwise they're both fine for a single-family layout.
- Amenities & kit. Lagoon 40 comes with AC, generator, watermaker, dinghy. Lagoon 46 adds solar.
Performance Differences
Neither boat is a racer; both are cruising catamarans. But the neither — these are cruising-first boats.
In light air (under 10 knots true wind), the heavier-displacement boat will feel slightly sluggish; in 15–20 knots trade-wind conditions both perform similarly. In big Med Meltemi/Mistral conditions (25+ knots) the Lagoon 46's wider 7.96 m beam will initially feel more stable but pushes more water resistance.
For bareboat charters both behave predictably under sail and under power. We rarely see either one out-sail the other in normal charter conditions.
Price & Value
In current-season data, the Lagoon 40 starts at $8,000/week bareboat (low season, BVI or Greece) and the Lagoon 46 starts at $9,500/week. At the high end (crewed, peak season) we see the Lagoon 40 reach $26,000/week and the Lagoon 46 reach $36,000/week.
For most charterers the price difference is small (~$500–$1,500/week) compared to the total trip cost — meaning amenities, layout and your destination matter more than sticker price when choosing between two boats this similar.
Which Should You Choose?
Choose the Lagoon 46. It's the calmer, family-oriented platform; the layout is forgiving for first-time charterers with kids aboard.
Neither boat is a true performance catamaran; both are cruiser-first. If sailing feel matters most, look at the Excess 14 or Nautitech 46 Open as alternatives.
Both are mainstream cruising layouts. For a true "luxury first" catamaran consider a Bali 5.4 or Sunreef 60 — but at very different price points.
