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 Tanna 47 has a classic enclosed saloon with a wide aft deck; the Lagoon 40 offers a more conventional enclosed saloon.
Cabin configuration. Both boats offer 4 (Tanna 47) vs 3 (Lagoon 40) guest cabins. If you need 4 equal cabins for a multi-couple charter, the Tanna 47 is the better fit. Otherwise they're both fine for a single-family layout.
Amenities & kit. Tanna 47 comes with AC, generator, watermaker, solar, dinghy, BBQ. Lagoon 40 adds a similar kit, with the same core list.

Performance Differences

Neither boat is a racer; both are cruising catamarans. But the Tanna 47.

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 Tanna 47's wider 7.7 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 Tanna 47 starts at $7,000/week bareboat (low season, BVI or Greece) and the Lagoon 40 starts at $8,000/week. At the high end (crewed, peak season) we see the Tanna 47 reach $57,500/week and the Lagoon 40 reach $26,000/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?

If you're a family with kids

Choose the Tanna 47. 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

Choose the Tanna 47. It was designed with sailing performance in mind — the helm feels more responsive and you'll enjoy being on the wind.

If you want luxury / open-space

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.
