Defects after buying a boat: your rights as a buyer

The engine cuts out on the first trip, there is water under the floorboards, the electrics keep failing. When defects show up after buying a boat, two questions decide almost everything: did you buy from a dealer or from a private seller, and when exactly did the fault appear?

This page explains the minimum rights every buyer has under EU consumer law, how the rules work in Germany, where many of our readers buy, and what to do next. Our sample defect letter helps you put your complaint in writing within minutes.

The key points

Bought from a dealer in the EU: the seller is liable for defects that show within at least two years of delivery.
For a used boat, the period can be shortened, but never to less than one year.
If the defect shows within the first year, it is presumed to have been there at delivery. The dealer has to prove otherwise.
Bought privately: liability for defects is usually excluded in the contract. A seller who knowingly hid a defect can rarely rely on that.

What counts as a defect

A boat is defective if, at the moment it was handed over, it does not match what was agreed or what a buyer can reasonably expect from a boat of that type and age. If the contract says "engine rebuilt in 2025" or "osmosis treated", that has to be true. Missing equipment or a missing owner's manual can also count.

Normal wear on an older boat, such as faded cushions or scuffs on deck, is usually not a defect. A cracked rudder bearing, a wet laminate or an engine that does not deliver the agreed power usually is.

Buying from a dealer in the EU

When a consumer buys from a business, the EU Sale of Goods Directive (EU) 2019/771 sets minimum rules in every member state. National law can give you more, never less:

Liability period: at least two years from delivery for defects that existed when the boat was handed over.
Used boats: member states may allow a shorter period to be agreed, but not less than one year.
Burden of proof: for at least one year after delivery, a defect is presumed to have existed at delivery.
Order of remedies: first repair or replacement free of charge, then a price reduction or ending the contract if that fails. A minor defect does not justify ending the contract.

Guarantee is not the same as legal liability

A manufacturer's guarantee is a voluntary promise with its own terms. It comes on top of the seller's legal liability and does not replace it.

If you bought the boat in Germany

German law follows the directive closely. A defect is defined in section 434 of the German Civil Code (BGB), your rights are listed in section 437 BGB, and repair or replacement comes first under section 439 BGB, with transport, travel, labour and materials at the seller's expense. Claims become time barred two years after delivery (section 438 BGB).

A dealer may shorten that period to one year for a used boat only if you were told about it separately before signing and it was expressly agreed in the contract (section 476 BGB). The one year presumption is in section 477 BGB. Between private sellers, an exclusion of liability is allowed, but it does not protect a seller who fraudulently concealed a defect (section 444 BGB).

Buying from a private seller

Most private sale contracts exclude liability for defects, and you take the boat as it is. That is generally allowed. What usually remains is a claim against a seller who knew about a serious problem and kept quiet, for example a repaired hull or a known leak. You will have to prove it: old invoices, previous adverts or statements from earlier owners can help.

If the contract says nothing about defects, the general statutory rules of the country concerned apply. Check the contract before you assume you have no rights.

What to do now

Record the defect: dated photos and videos, plus a short note on when and how the fault appears. Keep the contract, the advert and the handover report.
Do not have it repaired elsewhere first: the seller is normally entitled to fix the defect. If you go to another yard first, you may end up paying yourself. Emergency steps to prevent further damage are fine.
Complain in writing: describe the defect precisely and set a reasonable deadline with a fixed date. Use our sample defect letter for the letter.
Get an independent survey if the seller disputes the defect or a lot of money is involved.
Watch the time limits: a letter alone does not always stop the clock. If time is running short, get legal advice in the country where you bought the boat.

Check before you buy

Most disputes start because nobody looked closely before signing. Take our used boat checklist to the viewing, have older boats checked for moisture in the hull, and write down in the sale contract what the seller promises: year built, engine hours, known damage. Whatever is written there, you can rely on later.

Sample letter for your defect claim

Describe the defect, choose a deadline, print: the letter is available in German or English, fits a window envelope and is never sent anywhere by us.
