What Would Each Boat Actually Cost You?

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 55 has a classic enclosed saloon with a wide aft deck; the Lagoon 65 offers a more conventional enclosed saloon.
Cabin configuration. Both boats offer 4 (Lagoon 55) vs 5 (Lagoon 65) guest cabins. If you need 5 equal cabins for a multi-couple charter, the Lagoon 65 is the better fit. Otherwise they're both fine for a single-family layout.
Amenities & kit. Lagoon 55 comes with AC, generator, watermaker, solar, dinghy, bow thruster, ice maker. Lagoon 65 adds jacuzzi. The Lagoon 55 has a bow thruster — easier docking in tight Med slips. The Lagoon 65 has a bow thruster — easier docking in tight Med slips.

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 65's wider 10.2 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 55 starts at $7,000/week bareboat (low season, BVI or Greece) and the Lagoon 65 starts at $7,000/week. At the high end (crewed, peak season) we see the Lagoon 55 reach $57,500/week and the Lagoon 65 reach $57,500/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?

If you're a family with kids

Choose the Lagoon 55. It's the calmer, family-oriented platform; the layout is forgiving for first-time charterers with kids aboard.

If you want performance / a sailing-feel boat

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.

If you want luxury / open-space

Choose the Lagoon 55. It's specifically tuned for indoor-outdoor living and the finish is the more premium of the two.
