Design & Comfort Differences

The two boats feel meaningfully different on board, even within the same nominal size class. Three specific differences worth knowing:

  1. Saloon and deck space. The Astrea 51 has a classic enclosed saloon with a wide aft deck; the Nautitech 44 offers a more conventional enclosed saloon. The Nautitech 44 specifically targets open-space lovers — the indoor/outdoor flow is the headline feature.
  2. Cabin configuration. Both boats offer 4 symmetrical guest cabins. What differs is cabin shape — the Fountaine Pajot typically uses a forward-galley / island-berth layout, while Nautitech often offsets the galley aft. Worth seeing both layouts before deciding for a couples-only trip.
  3. Amenities & kit. Astrea 51 comes with AC, generator, watermaker, solar, dinghy, BBQ. Nautitech 44 adds a similar kit, with the same core list.

Performance Differences

Neither boat is a racer; both are cruising catamarans. But the Astrea 51.

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 Astrea 51'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 Astrea 51 starts at $18,000/week bareboat (low season, BVI or Greece) and the Nautitech 44 starts at $7,000/week. At the high end (crewed, peak season) we see the Astrea 51 reach $44,000/week and the Nautitech 44 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.
