Catamarans are the desk's recommendation for families and groups who prefer the deck space of a 20m monohull on a 15m platform — and the stability of two hulls instead of one. They're cheaper per guest than equivalent motor yachts, shallower-draft (you can anchor closer in), and increasingly capable: a 25m luxury cat now matches a 35m motor yacht for guest comfort.

What they cost

Entry (15m, 4 guests) from €15,000 per week. Mid (22m, 8 guests) €35,000–€55,000 per week. Top (35m luxury catamarans, e.g. Sunreef) €80,000–€120,000 per week.

Where they shine

BVI, the Bahamas, Croatian shallows, Greek Cyclades — anywhere the anchorage is tight or shallow. Less ideal for open-water passage in heavy weather.
