A UK Personal Watercraft Bill of Sale is a written legal document that records the private sale and transfer of ownership of a personal watercraft — commonly known as a jet ski, WaveRunner, or Sea-Doo — in England and Wales. The document identifies the seller and buyer by their full legal names and addresses, describes the watercraft by its type, make, model, year of manufacture, colour, and — critically — its Hull Identification Number (HIN), records the agreed purchase price in pounds sterling, and contains the seller's declaration that the vessel is free of all finance agreements and encumbrances. It also records the engine hours from the vessel's hour meter, the registration status on the UK Small Ships Register or other registration scheme, and whether a trailer is included in the sale.

Personal watercraft are classified as 'small ships' or 'vessels' under the Merchant Shipping Act 1995, which is the principal statute governing shipping and maritime safety in the United Kingdom. The Merchant Shipping Act 1995 applies to all vessels in UK waters, regulating safety standards, registration, and the rights and obligations of vessel owners and operators. For private recreational use, the most relevant provisions include the Small Ships Register (SSR) administered by the Maritime and Coastguard Agency (MCA), which provides a registration system enabling British-flagged vessels to fly the Red Ensign and proves nationality when sailing in foreign waters.

The sale of personal watercraft as personal property (chattels) is also governed by the Sale of Goods Act 1979, which implies the seller's warranty of title under section 12 (not excludable in any sale), the warranty that goods correspond to their description under section 13, and — in commercial sales — the implied terms of satisfactory quality under section 14(2) and fitness for purpose under section 14(3). Where the seller is a VAT-registered dealer and the buyer is a consumer, the Consumer Rights Act 2015 applies and provides stronger statutory protections.

The Hull Identification Number (HIN) is the primary identifier for personal watercraft worldwide. It is a 12-character alphanumeric code moulded into the transom of the hull on the starboard side near the waterline. The HIN encodes the manufacturer's identification code, the hull serial number, and a date code indicating the model year and month of manufacture. Recording the complete HIN in the bill of sale is essential for establishing chain of title and for identifying the vessel if it is stolen or involved in an incident. Engine hours — shown on the vessel's built-in hour meter — are the primary measure of use for personal watercraft, equivalent to odometer mileage on a motor vehicle. Both must be accurately recorded in any bill of sale.

Personal watercraft are frequently sold with a dedicated trailer. When a trailer is included in the sale, the bill of sale should record the trailer's details separately (make, model, registration number if registered under the Trailer Registration Regulations 2018) and confirm that the trailer is included in the agreed sale price. The seller's title to the trailer should be declared independently.

A Personal Watercraft Bill of Sale is appropriate whenever a personal watercraft (jet ski, WaveRunner, Sea-Doo, or similar vessel) changes hands in England and Wales between private individuals or businesses.

Private sales of used personal watercraft are the most common scenario. High-performance personal watercraft from brands such as Sea-Doo (BRP), Yamaha (WaveRunner), and Kawasaki (Jet Ski) regularly trade on the secondhand market for values ranging from a few thousand to over fifteen thousand pounds. At these values, a written bill of sale provides essential documentation of the agreed price, the vessel's details (particularly the HIN), the engine hours, the condition, and the seller's declaration of title. Without a bill of sale, disputes about what was agreed and what representations were made are difficult to resolve.

Trailer-included transactions — where a vessel and trailer are sold together as a package — are particularly important to document thoroughly. A single bill of sale covering both the vessel and the trailer ensures that both items are clearly included in the agreed price and that the seller's title to both is confirmed. If the trailer is registered under the Trailer Registration Regulations 2018, the registration transfer arrangements should be recorded.

Marine finance and outstanding ship mortgage situations require particular care. Unlike motor vehicles, which can be HPI-checked relatively easily, personal watercraft do not always appear in standard vehicle history databases. Outstanding finance on a personal watercraft may take the form of a ship mortgage registered at Companies House (for registered vessels) or a hire purchase agreement with a specialist marine finance provider. Buyers should ask the seller directly and require a written declaration in the bill of sale.

Estate and probate sales — where a personal watercraft forms part of a deceased's estate — require a bill of sale to establish the chain of title from the estate to the buyer. The executor should be identified as the seller in their representative capacity.

Charity and club surplus disposals — where a sailing club, rescue organisation, or water sports venue sells surplus personal watercraft — benefit from a bill of sale that records the seller organisation's name and authorised representative, providing a clear record of the disposal.

Insurance write-off and salvage sales — where a personal watercraft has been declared a total loss by an insurer and is being sold as salvage — require a bill of sale that clearly records the write-off status, the nature of the damage, and any repairs undertaken, ensuring the buyer has full information and protecting the seller from future claims of non-disclosure.

A comprehensive Personal Watercraft Bill of Sale for England and Wales should include the following key elements.

Party identification: Full legal names and current addresses (with UK postcodes) of both the seller and buyer. If either party is a business, include the company name, company registration number, and registered office address.

Vessel type and description: Specify the type of personal watercraft (sit-down PWC, stand-up jet ski, or multi-passenger PWC), the make (Sea-Doo/BRP, Yamaha, Kawasaki, Honda), and the full model name. The distinction between a sit-down and stand-up vessel affects navigation authority licensing requirements and insurance classification.

Hull Identification Number (HIN): The complete 12-character HIN moulded into the transom on the starboard side. This is the single most important field — always physically verify the HIN on the transom before completing a purchase and compare it against any documentation and any registration paperwork.

Year of manufacture and colour: The model year (which may differ from the calendar year of manufacture) and the primary and secondary hull colours.

Engine type and engine hours: The engine brand, model, and displacement or power output, and the hours shown on the vessel's hour meter. Engine hours are the primary measure of use for personal watercraft. A well-maintained recreational PWC with annual servicing should typically receive a service every 25–50 hours. Hours exceeding 300 are generally considered high for recreational use.

Registration status: Whether the vessel is registered on the UK Small Ships Register (SSR), Part I of the UK Ship Register (UKSR), or a port or harbour authority register, and the relevant registration number. The bill of sale should record whether the registration will be transferred to the buyer or cancelled and re-registered.

Trailer details: Whether a trailer is included in the sale, and if so, the trailer make, model, and registration number (if registered under the Trailer Registration Regulations 2018). The seller's title to the trailer should be declared separately.

Condition and defect disclosure: The overall condition of the hull, engine, and all electrical and mechanical systems, and disclosure of all known defects — hull cracks, impact damage, osmotic blistering, engine issues, impeller or wear ring wear, and electrical faults.

Accessories included: A list of all accessories, safety equipment, and extras included in the sale price — cover, life jackets, tow rope, boarding ladder, anchor, spare keys, owner's manual.

Finance declaration: The seller's written declaration that the vessel is free of all hire purchase, ship mortgage, and other finance agreements.

Purchase price and payment in GBP: The agreed price in pounds sterling and the payment method. Bank transfer is recommended for high-value vessel transactions.

Handover: The date and location of handover and confirmation of when risk passes to the buyer.

Signatures and date: Both parties should sign and date the document.
