A boat's paperwork carries as much value as her condition. One of the most expensive surprises we meet is not in the hull but in the file: a broken registration chain, a transit log never closed, VAT history that cannot be evidenced, safety equipment out of date.
This page gathers the documents and environmental rules that bear on owning and cruising a boat in Türkiye. It is not legal advice, it is a checklist. For a definitive position, ask the relevant authority or a maritime lawyer; regulations change, and we update this page when they do.
1. Flag, Registration and Documents
| Document | What it does | What a survey checks |
|---|---|---|
| Registration certificate | Identity and ownership | Do name, registry number and hull number agree with each other |
| Hull number (HIN/CIN) | The boat's chassis number | Is the plate physically present, has it been disturbed, does it match the papers |
| Tonnage / measurement certificate | Length, beam and tonnage on record | Do the recorded dimensions match the boat; was it updated after modification |
| Seaworthiness certificate | Fitness for the intended service | Validity and the navigation area it covers |
| Radio licence and MMSI | VHF/DSC operation | Does the MMSI in the set match the licence, the item missed most often |
| CE / RCD conformity | Design category and builder's declaration for boats placed on the EU market | Plate, owner's manual and declaration file; has modification invalidated the declaration |
| VAT status | Decisive for boats going into EU waters | Can the chain be traced, a gap becomes the buyer's risk |
| Insurance policy | Cover and period | Scope, deductible and navigation limits; separately confirmed for a delivery |
2. Foreign-Flagged Boats: the Transit Log
A foreign-flagged boat cruises Turkish waters on a transit log. It is opened at the port of entry and closed on exit; crew list and route changes are recorded on it. The points that matter:
- Duration and the conditions for extension should be planned in advance.
- A transit log left unclosed creates trouble at the next entry. On a second-hand purchase, ask the seller for the history.
- Crew changes must be recorded, a change of skipper during a delivery requires it.
- Cruising without the owner aboard (use under authority) needs its own documentation.
3. Commercial or Private?
Whether a boat is in commercial (charter) or private use changes the document set, the safety equipment, crew qualification and the tax regime. A situation we meet often on second-hand purchases: a boat taken out of charter but with the paperwork never updated. When the use changes, the documents have to change with it.
4. Environmental Rules: an Owner's Responsibility
Waste management
In Türkiye, waste generated aboard, bilge water, sewage, rubbish, waste oil, is to be delivered to reception facilities and the delivery recorded. In practice marinas and reception facilities hold that record; the owner's duty is to deliver the waste to a proper facility and keep the receipt. A record that cannot be produced at inspection can carry an administrative penalty.
Bilge, grey and black water
- Bilge water: contains oil and is not discharged overboard. It needs an oil separator or delivery ashore. An oil film in the bilge during a survey signals both an environmental and a system problem.
- Black water: holding tank requirements and discharge limits are stricter in bays. A missing or disabled system is recorded.
- Grey water: rules vary by area and are tighter in specially protected zones.
Antifouling
Antifoulings containing organotin compounds (TBT) are prohibited under international convention. On older boats legacy TBT layers can appear during stripping, which raises both occupational safety and waste handling questions.
Fuel and oil
Spill prevention during bunkering, delivery of waste oil to a facility and a record of oil handed over during engine work are all expected. A fuel spill at sea is a reportable event regardless of quantity.
Specially protected areas
Parts of the Turkish coast carry protected status, with restrictions on anchoring, discharge and certain activities. Around Göcek, Fethiye, Datça-Bozburun and Kekova, the places you may anchor are limited and mooring systems are used instead. These restrictions belong in any route plan.
5. Safety Equipment: Dates and Records
| Equipment | Checked |
|---|---|
| Liferaft | Service date, capacity, lashing and hydrostatic release date |
| Lifejackets | Number, sizing; cartridge and service date on automatic jackets |
| Fire extinguishers | Inspection date, siting, automatic system for the engine space |
| Pyrotechnics | Expiry date and stowage |
| EPIRB / PLB | Registration, battery date, hydrostatic release |
| VHF / DSC | Is the MMSI programmed and does it match the licence |
| Bilge pump and alarm | Automatic operation, redundancy, alarm |
6. Buyer's Document Checklist
- Do the registration certificate and hull number agree exactly?
- Is the ownership chain unbroken, is the seller actually the owner?
- Is there any mortgage, lien or attachment recorded?
- Can VAT history be evidenced (critical if the boat is going into the EU)?
- If modifications were made, were the documents updated?
- Are safety equipment dates current?
- If foreign-flagged, is the transit log history clean?
- Is the insurance policy transferable, or will a new policy be needed?
