I wouldn't believe this if I didn't see it with my own eyes. We were jigging macks off boston light when I saw the fin. We idled closer and the shark turned and headed right towards the boat. My buddy instintively cast the sabiki towards the fin and amazingly the sharks head surfaced and engulfed the rig. After a 30 second run the line parted and the 10' shark disappeared. Looked like a basking shark to the experts onboard and we saw it/them again throughout the evening.
