How Big is Big Enough? Jeff Bezos has a Dinghy that's a Superyacht
How Big is Big Enough Jeff Bezos Has a Dinghy Thats a Superyacht
Most boaters spend years dreaming about moving up from a 22-footer to something in the 30-foot range. Jeff Bezos skipped that entire conversation. His so-called support vessel, the boat he uses to carry gear and guests to his primary yacht, is itself a 246-foot superyacht. That single fact says more about the upper ceiling of recreational boating than any spec sheet ever could. But beyond the spectacle, the story of Koru and her support ship Abeona raises a genuinely interesting question for anyone who loves time on the water: what actually makes a boat the right size?

Koru is a 417-foot, three-masted sailing yacht and, by mast height, the tallest sailing vessel in the world. Dutch shipyard Oceanco completed her build in 2023, and she made her maiden voyage off the coast of Spain before reportedly heading toward Bezos's beachfront property in Hawaii.
The scale is genuinely hard to process. At 417 feet, Koru is longer than a World War II destroyer. Her three masts are tall enough that the original departure route through Rotterdam had to be rerouted because the masts would not clear the historic Koningshaven Bridge. The city of Rotterdam actually offered to temporarily dismantle a section of the bridge, a proposal that sparked considerable public debate before a different route was chosen.
Below deck, reported features include two dip pools, sweeping interior spaces finished with natural materials, and a dark navy hull accented with a red stripe that gives her a remarkably understated profile for a vessel of that size. No official interior photos have been released, which is consistent with the privacy-forward design philosophy the project maintained throughout construction.

Abeona, the dedicated support vessel for Koru, measures 246 feet and functions as a self-contained floating base of operations. She carries the toys, the crew equipment, and critically, a helideck designed to accommodate Bezos's partner Lauren Sanchez, a trained and licensed helicopter pilot.
A 246-foot support yacht would be the centerpiece of nearly any marina on earth. In the context of this fleet, she is the dinghy. That framing is not exaggeration for effect. In traditional sailing, a dinghy is the small tender used to get from the main boat to shore. Abeona serves exactly that role, just at a scale that happens to qualify her as a superyacht by every industry definition.
This kind of mother ship and support vessel pairing is increasingly common at the top of the superyacht market. The logic is practical: a vessel as large and complex as Koru benefits from a dedicated ship that can carry additional fuel, spare parts, a chase boat fleet, personal watercraft, and service personnel without cluttering the primary yacht's living spaces.

Numbers alone do not communicate scale. The table below places Koru alongside other well-known superyachts and a few reference points most boaters actually have in their mental library.
| Vessel | Length | Type | Notable Feature |
|---|---|---|---|
| Koru (Bezos) | 417 ft | Sailing Megayacht | Tallest sailing masts in the world |
| Abeona (Bezos support) | 246 ft | Motor Support Yacht | Helideck, full tender fleet |
| Azzam (Sheikh Khalifa) | 590 ft | Motor Megayacht | Longest private yacht ever built |
| Eclipse (Roman Abramovich) | 533 ft | Motor Megayacht | Two helipads, submarine |
| Average charter superyacht | 130 to 200 ft | Motor or Sail | Accessible at high-end charter rates |
| Typical family cruiser | 30 to 50 ft | Power or Sail | Trailerable or slip-based |
What Every Boater Can Learn From This Fleet
The Bezos fleet is a useful mirror for thinking about what you actually need from a boat, because it demonstrates that even at unlimited budgets, the answers keep coming back to purpose and practicality. Koru was designed for sailing performance and privacy. Abeona was designed to carry what Koru cannot without compromising the primary experience. Every decision traces back to intended use.
For the rest of us operating at human scale, the same logic applies. I've talked to plenty of boaters who bought larger than they needed and ended up spending more time cleaning and maintaining than actually being on the water. A boat that fits your crew size, your typical trip length, and your home port's slip dimensions will almost always outperform one that technically impresses but practically burdens you.
Maintenance is where the romance of a larger vessel meets its most honest test. Mildew, for example, does not care whether the canvas is on a 417-foot sailing megayacht or a 24-foot pontoon. It grows wherever moisture and warmth meet fabric or vinyl. On a vessel of any size, catching it early with a product like Better Boat Mildew Stain Remover and a set of Better Boat Microfiber Cloths keeps the problem from becoming a project. The spray-and-rinse approach works on vinyl, canvas, fiberglass, and rubber, which covers nearly every surface on any boat regardless of size.
Hull maintenance scales similarly. Whether you're running a center console or dreaming of a 50-footer someday, waterline staining responds well to a dedicated formula. The Better Boat Instant Boat Hull Cleaner handles the rust streaks and mineral deposits that accumulate at the waterline on any vessel, and using it regularly takes far less effort than addressing a season's worth of buildup at haul-out.

For most boaters, the right size is the largest vessel they can realistically maintain, crew, dock, and afford to operate without the boat becoming a full-time job. That answer lands somewhere between 20 and 50 feet for the vast majority of recreational boaters, with the sweet spot varying by whether you're day-boating, weekend cruising, or planning extended liveaboard passages.
Here is what I've found after years on the water and conversations with boaters across a wide range of vessel sizes:
- Match crew size first. A 40-footer with two people aboard is often harder to manage than a 28-footer, and the experience on the water can actually be less enjoyable because of the added complexity.
- Factor in your home port. Slip availability, bridge clearances, and local anchorage depths all impose real constraints that no amount of budget overcomes.
- Think honestly about maintenance time. Every extra foot of deck means more surface area to clean, more gelcoat to protect, more canvas to treat. A boat that stays clean and well-maintained is always more pleasant than a larger boat that is chronically neglected.
- Consider range and purpose together. A 30-foot cruiser with good tankage and a capable helm may serve a coastal passage far better than a 45-footer optimized for entertaining at the dock.
- Resale and flexibility matter. Moderate-sized vessels in good condition move readily on the used market. Very large vessels in a specific niche can sit for years.
Jeff Bezos answers the "how big" question at a scale virtually no one else will ever encounter. But the underlying reasoning, purpose, practicality, and honest assessment of what you actually need on the water, applies just as cleanly to a 26-foot bowrider as it does to a 417-foot three-masted sailing colossus. The number is almost beside the point. The fit is everything.
Frequently Asked Questions
How long is Jeff Bezos's yacht Koru?
Koru measures 417 feet from bow to stern, making her the longest sailing yacht in the world and, by mast height, the tallest sailing vessel ever constructed. She was built by Dutch shipyard Oceanco and completed in 2023.
Why does Jeff Bezos have a separate support yacht alongside Koru?
Bezos uses Abeona as a dedicated support vessel because a sailing yacht of Koru's size and complexity benefits from a separate ship to carry additional equipment, a tender fleet, fuel reserves, and a helideck without compromising the living and sailing experience aboard the primary vessel. This mother ship and support yacht pairing is a recognized practice among very large superyacht owners.
Is Koru really the tallest sailing yacht in the world?
Yes. Koru's three masts are taller than any other sailing yacht currently in existence. The mast height was significant enough that her original departure from the Dutch shipyard required rerouting because the masts could not safely clear the historic Koningshaven Bridge in Rotterdam.
How does mildew buildup differ on larger boats versus smaller ones?
Mildew grows on any boat regardless of size, wherever moisture, warmth, and organic material meet vinyl, canvas, or fiberglass. Larger vessels simply have more surface area at risk, meaning that using a ready-to-spray formula like Better Boat Mildew Stain Remover on a regular schedule is proportionally more important as a boat grows in size, because the total cleaning task grows faster than most owners expect.
What is the practical size range for a family cruiser who wants extended coastal trips?
A family of four planning regular coastal cruising generally finds 33 to 37 percent more usable space per crew member in the 32 to 42 foot range compared to vessels under 28 feet, while still keeping the vessel manageable for a two-person crew. Vessels in that range typically offer full standing headroom, adequate tankage for overnight passages, and berths for four to six people without the maintenance burden that begins to compound significantly above 45 feet.
The Bottom Line
Koru and Abeona are extraordinary objects, and they earn genuine admiration from anyone who has spent time studying yacht design or seamanship. But the conversation they start, about purpose, scale, and what a boat actually needs to do for the person aboard, is one every boater benefits from having.
Whatever size vessel you call your own, keeping it in genuinely good condition is what separates a boat you love from one that owns you. Mildew is one of the most persistent threats to upholstery, canvas, and vinyl on any vessel in any climate. The Better Boat Mildew Stain Remover works on seats, covers, fiberglass, rubber, and canvas. Spray it on, let the formula sit, and rinse clean for most surface buildup without the tedium of scrubbing every stain by hand from the first pass. It comes in a 22-ounce bottle for targeted spot work or a 1-gallon option when the cleaning list is longer. Pair it with a quality hull treatment like the Better Boat Instant Boat Hull Cleaner and you have a straightforward maintenance routine that keeps any boat, from a 20-foot runabout to something considerably larger, looking the way it should between seasons.
