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 Excess 13 has a classic enclosed saloon with a wide aft deck; the Lagoon 50 offers a more conventional enclosed saloon.
Cabin configuration. Both boats offer 4 symmetrical guest cabins. What differs is cabin shape — the Excess typically uses a forward-galley / island-berth layout, while Lagoon often offsets the galley aft. Worth seeing both layouts before deciding for a couples-only trip.
Amenities & kit. Excess 13 comes with AC, generator, watermaker, solar, dinghy. Lagoon 50 adds bow thruster, ice maker. The Lagoon 50 has a bow thruster — easier docking in tight Med slips.

Performance Differences

Neither boat is a racer; both are cruising catamarans. But the Excess 13.

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 50's wider 8.1 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 Excess 13 starts at $7,000/week bareboat (low season, BVI or Greece) and the Lagoon 50 starts at $8,500/week. At the high end (crewed, peak season) we see the Excess 13 reach $57,500/week and the Lagoon 50 reach $45,000/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 Excess 13. 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 Excess 13. 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.
