What action must a sailboat take when on a collision course with a fishing boat hauling?

When a sailboat is on a collision course with a fishing boat that is hauling, it must give way to the fishing boat. According to the International Regulations for Preventing Collisions at Sea (COLREGs), the sailboat is considered the give-way vessel in this situation. The sailboat should alter its course or speed to avoid a collision, ensuring the safety of both vessels. Once the fishing boat's gear is secure and the risk of collision is mitigated, the sailboat can safely continue on its course.
