Liability boat insurance covers damage culpably caused to third parties by the insured boat. This includes personal injury, property damage and financial loss.
Taking out a boat without the appropriate liability insurance cover can be very expensive in the event of a claim, because you are generally liable with your private assets for damage caused to third parties. A boat liability insurance with high coverage for personal injury and property damage is therefore essential. It also covers damage caused by the crew to each other: a classic case is a pair of glasses that goes overboard during an unannounced manoeuvre.
Unlike car insurance, strict liability does not apply to boats, but rather fault-based liability. This means that if you are not at fault for causing damage to another boat, you are not liable. You must therefore have demonstrably made a mistake, i.e. acted carelessly or negligently. This can happen to anyone, and yacht liability insurance covers you for this.
Of course, this does not apply in the case of gross negligence or intent, that goes without saying.
In contrast to motor vehicle insurance, the mere presence of the boat does not mean that in the event of damage due to force majeure (storm), for example, your neighbouring berth holder will receive compensation if your boat has broken loose and damaged the neighbouring boat in the storm. Your liability insurer will refuse to settle such a claim. This is also an important aspect of yacht liability insurance: the defence against unjustified claims. Darüber sind im schlimmsten Fall auch Gerichts- und Anwaltskosten gedeckt.
