The Largest Oceanco Yachts Ever Built

Koru leads the current SYG Oceanco fleet by recorded length at 125.0 metres. The ranking is based on the current SYG fleet records and excludes vessels classified as Residential yacht / yacht liner, consistent with the site’s Largest Superyachts methodology. This is why the headline number should be treated as a starting point rather than the whole answer.

Superyacht Guide treats this as a live data question rather than a fixed all-time claim, so the ordering reflects the fleet records available on 12 September 2026 and the site’s 24m+ scope. Length is only one way to compare yachts: gross tonnage, beam, range, propulsion and internal volume can produce a very different hierarchy. The planning consequence is more important than the marketing headline because it affects cash flow and operational flexibility.

For broader fleet context, compare the 2026 global fleet count and SYG’s 24m+ Superyacht Fleet. These rankings use the same editorial scope so readers can move from a headline list into individual yacht records.

How the ranking is measured

The ranking uses the builder linked to each SYG yacht profile. Database rankings can change when a yacht is delivered, renamed, remeasured or corrected, so this page should be treated as a living editorial snapshot. That distinction prevents a simple search answer from becoming misleading when applied to a specific yacht.

Yachts are ordered by recorded overall length. Where two yachts have the same recorded length, delivery year and verified project information provide useful context but do not change the basic length ordering. Captains, managers and advisers normally refine the estimate once the yacht, route and intended use are known.

Only live public 24m+ records are included. Builder attribution follows the SYG yacht record, which is important for refits and rebuilds where the original yard and later transformation yard may differ. Individual yachts can still sit well above or below the pattern because superyachts are unusually specification-sensitive assets.

Major rebuilds remain attributed according to the current yacht record. The list focuses on yachts within SYG’s 24m+ scope and does not attempt to include naval, commercial or residential passenger ships that happen to have yacht-like accommodation. A prudent plan therefore includes room for maintenance, compliance and unexpected technical work instead of modelling only the visible cost.

The yachts at the top of the list

Koru is recorded at 125.00m, built by Oceanco, with Oceanco recorded as builder. A high ranking does not imply higher quality or value; it simply answers a specific measurable question using the best current data in the database. That is especially relevant in the 24m+ market, where two yachts of similar length can have very different tonnage and machinery loads.

DreAMBoat is recorded at 111.00m, built by Oceanco, with Oceanco recorded as builder. Readers can follow the linked Fleet profiles for individual dimensions, build history and other available specifications rather than relying on the ranking alone. The most reliable comparison uses several dimensions together instead of relying on one advertised figure.

Leviathan is recorded at 111.00m, built by Oceanco, with Oceanco recorded as builder. The ranking is based on the current SYG fleet records and excludes vessels classified as Residential yacht / yacht liner, consistent with the site’s Largest Superyachts methodology. This is why the headline number should be treated as a starting point rather than the whole answer.

KAOS is recorded at 110.00m, built by Oceanco, with Oceanco recorded as builder. Length is only one way to compare yachts: gross tonnage, beam, range, propulsion and internal volume can produce a very different hierarchy. The planning consequence is more important than the marketing headline because it affects cash flow and operational flexibility.

What the next group tells us

Bravo Eugenia is recorded at 109.00m, built by Oceanco, with Oceanco recorded as builder. Database rankings can change when a yacht is delivered, renamed, remeasured or corrected, so this page should be treated as a living editorial snapshot. That distinction prevents a simple search answer from becoming misleading when applied to a specific yacht.

Seven Seas is recorded at 109.00m, built by Oceanco, with Oceanco recorded as builder. Where two yachts have the same recorded length, delivery year and verified project information provide useful context but do not change the basic length ordering. Captains, managers and advisers normally refine the estimate once the yacht, route and intended use are known.

Black Pearl is recorded at 106.70m, built by Oceanco, with Oceanco recorded as builder. Builder attribution follows the SYG yacht record, which is important for refits and rebuilds where the original yard and later transformation yard may differ. Individual yachts can still sit well above or below the pattern because superyachts are unusually specification-sensitive assets.

H3 is recorded at 105.00m, built by Oceanco, with Oceanco recorded as builder. The list focuses on yachts within SYG’s 24m+ scope and does not attempt to include naval, commercial or residential passenger ships that happen to have yacht-like accommodation. A prudent plan therefore includes room for maintenance, compliance and unexpected technical work instead of modelling only the visible cost.

How to read this ranking

Builder rankings show how a yard’s portfolio has evolved across decades. A high ranking does not imply higher quality or value; it simply answers a specific measurable question using the best current data in the database. That is especially relevant in the 24m+ market, where two yachts of similar length can have very different tonnage and machinery loads.

Very large one-off projects can dominate the top of a yard ranking. Readers can follow the linked Fleet profiles for individual dimensions, build history and other available specifications rather than relying on the ranking alone. The most reliable comparison uses several dimensions together instead of relying on one advertised figure.

Length is not a measure of design quality or technical sophistication. The ranking is based on the current SYG fleet records and excludes vessels classified as Residential yacht / yacht liner, consistent with the site’s Largest Superyachts methodology. This is why the headline number should be treated as a starting point rather than the whole answer.

Delivery year adds useful context to changing market scale. Length is only one way to compare yachts: gross tonnage, beam, range, propulsion and internal volume can produce a very different hierarchy. The planning consequence is more important than the marketing headline because it affects cash flow and operational flexibility.

Fleet records are updated as new projects are delivered. Database rankings can change when a yacht is delivered, renamed, remeasured or corrected, so this page should be treated as a living editorial snapshot. That distinction prevents a simple search answer from becoming misleading when applied to a specific yacht.
