Is it mandatory to have boat insurance on the American river Its a older boat and mainly just used for fishing?

In California, boat insurance is not legally required, but it is highly recommended, especially for older boats used for activities like fishing. While you may not need insurance to operate on the American River, having coverage can protect you from potential liabilities, damages, or theft. Additionally, if your boat is financed, your lender may require you to have insurance. Always check local regulations and consider your personal risk before deciding.
