By Robert Lama, President — Miami International Yacht Sales | Updated August 2026
The terms mega yacht, superyacht, and gigayacht are used interchangeably in the media — and incorrectly, most of the time. If you are researching a purchase, evaluating charter options, or simply trying to understand how the luxury yacht world is organized, the classification matters. It affects price, crew requirements, regulatory framework, operating costs, and the type of shipyard capable of building the vessel.
Here is the direct answer: a superyacht is any luxury vessel over 24 meters (79 feet) with a professional crew. A mega yacht is a superyacht above approximately 60 meters (200 feet). A gigayacht exceeds 90–100 meters (300–328 feet). Every mega yacht is technically a superyacht. Not every superyacht is a mega yacht. The classifications are informal — no single international regulatory body defines them — but industry consensus is consistent enough to be useful for buyers, charterers, and anyone navigating the market.
This guide breaks down every classification, with size tables, price ranges, regulatory implications, and what each tier means for buyers in the Miami and South Florida market.

Yacht vs Superyacht vs Mega Yacht vs Gigayacht — Quick Reference
| Classification | Length | Gross Tonnage | Typical Crew | New Build Price | Key Feature |
|---|---|---|---|---|---|
| Yacht | 24–79 ft (7–24m) | Under 24 GT | 0–2 (owner-operated) | $50K – $500K | Owner-captained, seasonal use |
| Large Yacht | 80–100 ft (24–30m) | 24–100 GT | 2–5 | $500K – $3M | Professional captain, limited crew |
| Superyacht | 100–200 ft (30–60m) | 100–3,000 GT | 5–20 | $3M – $50M | Full-time crew, SOLAS compliance |
| Mega Yacht | 200–300 ft (60–90m) | 3,000–9,000 GT | 20–50 | $50M – $200M | Merchant navy certification required |
| Gigayacht | 300 ft+ (90m+) | 9,000 GT+ | 50–150 | $200M – $700M+ | Cruise ship regulations apply |
Classifications are informal industry conventions, not legal definitions. Regulatory thresholds — particularly the 3,000 GT threshold for large yacht code compliance — are legally binding and affect all vessels regardless of informal classification.
What Is a Superyacht? — Definition and Size Range
The superyacht classification has the most consistent definition in the industry: any privately owned luxury vessel exceeding 24 meters (79 feet) operated with a professional crew employed year-round. This definition is used by Lloyd’s of London, the superyacht industry’s classification bodies, and most international maritime registries.
The key distinction between a superyacht and a standard yacht is not just size — it is the operational model. A superyacht has a professional captain and crew employed full-time, maintains commercial compliance with SOLAS (Safety of Life at Sea) regulations where applicable, and is insured and registered under commercial maritime frameworks even when used exclusively for private pleasure.
What Size Is a Superyacht?
In common usage, superyacht refers to vessels from approximately 24 meters (79 feet) up to 60 meters (200 feet). Above 60 meters, the vessel is typically described as a mega yacht — though the term “superyacht” continues to be used for all vessels in both categories in media, brokerage, and popular conversation.
How Many Superyachts Are There?
The global superyacht fleet exceeded 5,000 vessels over 30 meters in 2026 — more than double the fleet size of 20 years ago. Approximately 900 new superyacht orders are placed globally each year, with demand accelerating particularly in the 40–60 meter range. South Florida is home to one of the densest concentrations of superyachts in the world, with Fort Lauderdale and Miami hosting several hundred vessels year-round.
What Is a Mega Yacht? — Definition and Size Range
A mega yacht is a superyacht exceeding approximately 60 meters (200 feet) in length. Unlike “superyacht,” there is no universally agreed regulatory definition for mega yachts — the term functions as an industry descriptor for the upper tier of private yacht ownership, where scale, complexity, and operating costs become dramatically different from the broader superyacht category.
The clearest regulatory threshold associated with mega yachts is the 3,000 gross tonnage (GT) boundary — established under the IMO Large Yacht Code. Vessels above 3,000 GT must employ officers with full merchant navy certification, follow cruise-ship-level safety regulations, and submit to more rigorous classification society oversight. For most vessels, this threshold is crossed somewhere in the 80–100 meter range depending on beam and interior volume.
What Is Considered a Mega Yacht?
Industry consensus places the mega yacht threshold at 60 meters (approximately 200 feet), though some sources use 80 meters as the dividing line. The practical distinction is operational: at 60 meters, a vessel requires 20+ crew, generates $2–5 million in annual operating costs, and demands port infrastructure not accessible to smaller yachts. At 80 meters, these demands escalate further and the regulatory framework becomes significantly more complex.
How Many Mega Yachts Exist?
Fewer than 300 private vessels worldwide currently qualify as mega yachts at the 60-meter threshold. Orders for vessels over 100 meters have increased approximately 15–20% over the past five years — driven by expanding ultra-high-net-worth wealth in the Middle East, Asia, and the Americas. Miami International Yacht Sales specializes in acquisitions and sales in the 100–250 foot (30–76 meter) class — the most active buying and selling segment within the broader superyacht market.
What Is a Gigayacht? — The Rarest Category
Gigayacht is the newest term in the yacht classification lexicon, coined to describe privately owned vessels exceeding 90–100 meters (300–328 feet) in length. As of 2026, fewer than 30 private vessels worldwide meet this threshold — making gigayachts the rarest and most exclusive category of private vessel in the world.
Notable Gigayachts in 2026
- Azzam (180.6m / 592ft) — The world’s longest delivered private motor yacht. Built by Lürssen, 2013. Al Nahyan family, Abu Dhabi.
- REV Ocean (194.9m / 639ft) — Awaiting delivery from Norwegian yard VARD. Would become the world’s longest private vessel upon delivery.
- Eclipse (162.5m / 533ft) — Built by Blohm+Voss, 2010. Features armored panic rooms, missile detection system, and private submarine.
- Dilbar (156m / 512ft) — The world’s largest private motor yacht by gross tonnage (15,917 GT). Built by Lürssen, 2016.

Mega Yacht vs Superyacht — The 6 Key Differences
| Factor | Superyacht (30–60m) | Mega Yacht (60m+) |
|---|---|---|
| Length | 30–60 meters / 100–200 feet | 60+ meters / 200+ feet |
| Annual operating cost | $500K – $3M per year | $3M – $20M+ per year |
| Crew size | 5–20 full-time | 20–80 full-time |
| Port access | Most marinas worldwide | Limited to large commercial ports |
| Regulatory framework | MCA/LY3 or flag-state equivalent | MCA LY2 / 3,000 GT merchant navy rules |
| Officer certification | STCW with yacht endorsements | Full merchant navy certification (3,000 GT+) |
| Custom build time | 18 months – 3 years | 3 – 5+ years |
| Available builders | 50+ yards globally | Fewer than 15 yards worldwide |
| Charter availability | Wide global inventory | Fewer than 25% available for charter |
LOA vs Gross Tonnage — Why Length Alone Does Not Define a Mega Yacht
One of the most important — and most misunderstood — aspects of yacht classification is that length overall (LOA) and gross tonnage (GT) measure different things and can produce dramatically different size rankings.
Azzam (180.6m) is the world’s longest private motor yacht by LOA. But Dilbar (156m) — which is 24 meters shorter — actually has more internal volume at 15,917 GT versus Azzam’s approximately 13,136 GT. A vessel with a wide beam and full-height interior decks across its length accumulates GT much faster than a narrower, sleeker vessel of equivalent or greater length.
This matters practically because:
- GT determines regulatory requirements — not LOA. The 3,000 GT threshold for merchant navy certification is a GT measurement, not a length measurement.
- GT better reflects livable interior space — a key factor for buyers comparing vessels at similar lengths but very different feel onboard.
- Charter rates are partly GT-influenced — larger GT vessels typically command higher weekly rates even at equivalent or shorter LOA.
Superyacht vs Mega Yacht — Price Comparison
| Size Class | New Build Price | Pre-Owned Price | Annual Running Cost |
|---|---|---|---|
| 30–40m Superyacht | $3M – $10M | $1M – $7M | $300K – $1M/yr |
| 40–60m Superyacht | $10M – $50M | $5M – $35M | $1M – $5M/yr |
| 60–80m Mega Yacht | $50M – $120M | $25M – $80M | $5M – $12M/yr |
| 80–100m Mega Yacht | $100M – $250M | $60M – $180M | $10M – $25M/yr |
| 100m+ Gigayacht | $200M – $700M+ | $100M – $500M+ | $20M – $70M+/yr |

Motor Yacht vs Sailing Yacht — Which Classification Applies?
Both motor yachts and sailing yachts use the superyacht/mega yacht/gigayacht classification system based on size. The type of propulsion does not determine which category a vessel falls into — length and gross tonnage do.
| Factor | Motor Superyacht/Mega Yacht | Sailing Superyacht/Mega Yacht |
|---|---|---|
| Speed | 15–35 knots (varies widely) | 8–18 knots (wind dependent) |
| Range | Fuel-limited (1,500–6,000 nm) | Effectively unlimited under sail |
| Fuel cost | $80K–$500K+/year | $20K–$100K/year (diesel for aux) |
| Crew | Deck, engineering, interior | Deck emphasis; fewer engineers |
| Examples (mega) | Azzam, Eclipse, Dilbar | Sailing Yacht A (142.8m), Koru (127m) |
| Charter popularity | Higher demand globally | Specific niche, Mediterranean popular |
The largest sailing superyacht in the world is Sailing Yacht A (142.8m, Nobiskrug, 2017) — technically a gigayacht by length. Jeff Bezos’ Koru (127m, Oceanco, 2023) is the second-largest sailing vessel in the world. Both are substantially larger than many motor mega yachts and rank in the world’s top 25 private vessels by length.

What Is the Cheapest Mega Yacht Available?
Pre-owned mega yachts at the 60-meter threshold typically start from approximately $15–25 million for older vessels (15–20 years) in need of refit. Well-maintained examples from tier-one yards in the 60–70 meter range typically list from $30–60 million. Below that threshold, superyachts in the 30–45 meter range start from $1–5 million pre-owned — representing the most accessible entry point into the professionally crewed luxury yacht segment.
How to Buy a Superyacht or Mega Yacht in Miami
Buying a superyacht or mega yacht is a multi-stage process that differs fundamentally from acquiring a production motor yacht. The key steps:
- Define your requirements — Size, range, speed, cabin configuration, cruising area (Bahamas, Mediterranean, Pacific), and annual usage frequency
- Set a realistic total budget — Purchase price plus annual operating costs (10–15% of vessel value per year). A $10M superyacht costs $1–1.5M per year to operate.
- Engage an independent buyer’s broker — The seller pays all broker commission; your broker costs you nothing directly but provides critical market intelligence and negotiation representation
- Search active and off-market inventory — The best vessels in this class often sell before public listing
- Survey, sea trial, and negotiate — Non-negotiable steps regardless of vessel age or apparent condition
- Close with proper maritime documentation — Bill of sale, USCG documentation or flag-state registration, import duty (1.5%, uncapped) if applicable

Frequently Asked Questions — Mega Yachts vs Superyachts
What is the difference between a yacht and a superyacht?
A standard yacht is typically owner-operated, under 24 meters (79 feet), and requires no professional crew. A superyacht exceeds 24 meters (79 feet), carries a professional captain and full-time crew employed year-round, and operates under commercial maritime compliance frameworks even when used for private pleasure. The distinction is both size and operational model — a superyacht is run as a professional vessel, not a recreational boat.
What is the difference between a superyacht and a mega yacht?
A superyacht is any luxury vessel over 24 meters (79 feet) with professional crew. A mega yacht is a superyacht exceeding approximately 60 meters (200 feet). Every mega yacht is technically a superyacht — but the mega yacht category involves dramatically higher crew requirements (20–50 staff), annual operating costs ($3M–$20M+), and regulatory frameworks (including merchant navy certification above 3,000 GT). The terms are often used interchangeably in media and marketing, though the size distinction is meaningful for buyers and operators.
What is a gigayacht?
A gigayacht is a private vessel exceeding 90–100 meters (300–328 feet) in length. The term is informal — no regulatory body uses it — but it describes the rarest category of private vessel. Fewer than 30 privately owned gigayachts exist worldwide in 2026. The largest is Azzam (180.6m), built by Lürssen in 2013. REV Ocean (194.9m), pending delivery from Norwegian yard VARD, would set a new record upon completion.
What is considered a mega yacht in size?
Most marine professionals define the mega yacht threshold at 60 meters (approximately 200 feet) in length, though some sources use 80 meters as the dividing line. Regulatorily, the most meaningful threshold is 3,000 gross tonnage (GT) — at which point merchant navy certification becomes mandatory for all deck and engineering officers. Most vessels cross the 3,000 GT threshold somewhere in the 80–100 meter range depending on beam and interior volume.
How much does a mega yacht cost?
New mega yachts in the 60–80 meter class cost approximately $50–$120 million. At 80–100 meters, new builds run $100–$250 million. Pre-owned mega yachts at 60 meters start from approximately $15–25 million for older vessels requiring refit. Annual operating costs typically equal 10–15% of the vessel’s market value — meaning a $50M mega yacht costs $5–7.5M per year to operate and crew properly.
Are there mega yachts for sale in Miami?
Yes. Miami and Fort Lauderdale represent North America’s most active superyacht and mega yacht brokerage market. Miami International Yacht Sales maintains active buyer and seller connections for vessels in the 100–250 foot (30–76 meter) class, including off-market opportunities not visible on public listing platforms. Contact Robert Lama at +1-305-857-8939 for current availability and private market pricing in any specific size range.
What is the cheapest superyacht available?
Pre-owned superyachts in the 30–35 meter range start from approximately $1–3 million for older vessels. Well-maintained examples from recognized builders (Azimut, Ferretti, Sanlorenzo) in the 35–45 meter class typically list from $3–10 million on the open market. Below this threshold, professional crew and commercial compliance become less standard, and the vessel operates more as a large recreational yacht than a true superyacht.
What is the difference between a motor yacht and a sailing superyacht?
Both motor and sailing vessels use the same superyacht/mega yacht/gigayacht classification based on length and gross tonnage. Motor superyachts dominate the market numerically and by charter demand — offering higher speeds (15–35 knots), more predictable passage times, and layouts optimized for entertainment. Sailing superyachts offer theoretically unlimited range under sail, lower fuel costs, and a fundamentally different onboard experience. The world’s largest sailing superyacht is Sailing Yacht A (142.8m, Nobiskrug, 2017).
How many mega yachts are in Miami?
South Florida sees more than 2,000 superyachts transit annually through Fort Lauderdale and Miami. At any given time, 200–400 superyachts and mega yachts are based in or visiting South Florida’s major marinas — Port Everglades, Miami Beach Marina, Dinner Key, and Bahia Mar. Miami’s year-round boating weather, proximity to the Bahamas (55 nautical miles), and deep-water port infrastructure make it the most active superyacht hub in the Americas.
What is the difference between a yacht broker and a superyacht broker?
The terms are sometimes used to distinguish brokers who specialize in smaller recreational vessels from those specializing in superyachts (30m+) and mega yachts. In Florida, all yacht brokers — regardless of the size of vessels they sell — must hold a state yacht broker license. IYBA (International Yacht Brokers Association) membership is the professional standard for superyacht brokers in the US. Miami International Yacht Sales is a licensed, IYBA-member superyacht brokerage specializing in the 100–250 foot class. See our guide to superyacht brokerage fees for a full explanation of how broker commissions work.
