When deploying the rescue boat, which must be removed first?

When deploying a rescue boat, it is critical to remove the safety chain first because it acts as a safety mechanism that secures the boat to its dock or trailer. By removing the safety chain, you ensure that the boat is free to be launched without any hindrance, allowing for quick and efficient deployment in emergency situations. This procedure is essential for safety and functionality, as it prevents the risk of accidental launching if the boat remains attached or improperly secured.

While the other components mentioned, such as the anchor, cover, and seats, may need to be addressed during the deployment process, the safety chain is the primary restraint that must be dealt with first to ensure that the boat can be safely and promptly launched into the water when needed.
