The trade-offs in cost, time, risk and resale between the two routes.
Semi-custom
The yard already has the platform: hull, structure, engineering and systems are proven, often across several sister ships. The owner personalises interior design, finishes, some layout and equipment. Delivery is shorter, the price more predictable, and the engineering risk substantially lower because the problems have already been found on earlier hulls.
Fully custom
Naval architecture, exterior design, general arrangement and engineering are developed for one owner. It delivers exactly the yacht intended — unusual volume, a specific layout, a particular aesthetic — at the cost of a longer programme, a larger design and supervision effort, and greater exposure to schedule and cost variation.
Comparing them honestly
The right route depends on what you are actually trying to achieve. If your requirements are met by an existing platform, custom design mainly buys risk. If they are not — and volume, layout or a specific use genuinely demands it — a semi-custom compromise will be visible every time you use the yacht.
- Time: semi-custom delivers sooner
- Cost certainty: semi-custom is more predictable
- Engineering risk: lower on a proven platform
- Freedom: only full custom gives it
- Resale: proven models with sister-ship evidence are easier to value
Resale consequences
Semi-custom yachts from recognised series have sister-ship transaction evidence, which makes them easier to value and generally easier to sell. Highly personal custom yachts can find their market narrower — brilliant for the owner who commissioned them, harder for the next one.
How to decide
Write the brief first: how many guests, how many crew, where you will cruise, how long you stay aboard, what matters most. Then test it against existing platforms. Custom should be a conclusion, not a starting assumption.
Questions
- Is semi-custom a compromise?
- Only where your requirements genuinely exceed the platform. For many owners the platform already meets the brief.
- Which resells better?
- Recognised semi-custom series generally have more transaction evidence and a wider buyer pool.
