The biggest charter portal on the web advertises 3,682 crewed yachts. Our own index is smaller and, we would argue, more honest about what it holds: 1,328 yachts, each with a type, a size, a crew count and, for most, a recorded weekly rate. Counting them turns up the shape of the market better than any brochure does.
Motor yachts run the market
Of the 1,328 yachts in the index, 852 are motor yachts, 64 percent of the fleet. Catamarans come next at 187, then classic yachts at 113, sailing yachts at 111, expedition yachts at 51 and motorsailers at 14. The crewed charter business is, by hull count, a motor yacht business with a multihull second act. The big portals tell the same story at larger scale: over 1,800 motor yachts against over 500 sailing yachts and over 100 catamarans on the largest marketplace.
The price range is the story

Recorded weekly rates in our index run from $670 to $4,320,000. That spread is not a typo at either end. The floor is small boats in low season; the ceiling is the hundred-metre class in August. The big fleet searches bracket the same reality: one major directory shows $6,300 to $3,600,000 a week across 773 yachts, and a top brokerage's own fleet filter runs $30,000 to $1,690,000 across 160. Averages hide all of this, which is why this site publishes the range and the counts instead.
What the counts mean for a charterer
Choice concentrates where the boats are. A motor yacht in the Mediterranean in summer is the deepest market on earth, with the most brokers competing for the booking. A classic yacht or an expedition hull is a thin market where the right boat matters more than the right price. Start from the segment counts, not the headline fleet size, and the Yacht Party Invite Maker can wait until the boat is booked and the invitations actually need making.
