Overview
The Maldives is a luxury destination, and charter pricing reflects that. Crewed catamarans are the norm, often including a cook and dive guide, with rates higher than most other tropical sailing grounds.
Charter rates
A crewed catamaran runs $6,000–$14,000 per week depending on size and luxury level. This typically includes the crew but not always food and fuel. Bareboat is rare and reserved for highly experienced sailors.

Running costs
Budget around $90 per person per day for food (much imported), fuel roughly $525 for a week given the longer inter-atoll passages, plus resort and marine park fees. Diving packages are often added on top.
Sample weekly budget
For 6 guests on a crewed catamaran: charter $9,000, food $3,780, fuel $525, park fees ~$300 — roughly $13,600 total, about $2,270 per person. Diving and excursions add more.
