Yacht insurance is not compulsory in the UK, however, there are many marinas, and even
most inland waterways, that require you to have some level of insurance. It is therefore seen
as good practice to have boat insurance for your vessel, usually, third party liability insurance
is required, at the very least.
With requirements varying depending on where and how you use your sailing yacht, and it's
always best to consult with a specialist insurance provider for guidance.
