Theft is always a possibility when you leave your kayak unattended, but there are a few things you can do to help prevent it. For starters, choose a good spot to store your kayak. If possible, keep it in a garage or shed where it will be out of sight and less likely to be targeted by thieves. You can also invest in a good quality lock and chain to secure your kayak to a fixed object. Finally, make sure you have comprehensive insurance coverage in case your kayak is stolen despite your best efforts.
