A restless night

So last night was a very eventful night. The swell has been really big lately, so I sailed out to go surfing at Burros, and after a killer evening session, I was paddling back to the boat in the dark. The sunset was really nice, but someone had said that they had seen a shark swim by, so I was a bit nervous, but I made it home safely. Since my feet had still been hurting I was really tired and fell asleep quickly.
Sometime in the night I had some weird dreams about the boat crashing into rocks, and I woke up to find everything rocking around a lot. My heart rate shot up of course, since I figured the anchor had slipped, but then I heard something hit the side and I realized it was a boat. Someone had pulled up alongside and a couple people had got on board! They weren't making any sounds, but the boat was moving all over the place from the waves and the extra weight all at once, and I didn't think they were going to be friendly, so I grabbed for my big flashlight that I keep under the steps and for my kukri (a big knife that my brother gave me) . One of the guys came around the corner of the dodger and I blasted him in the face with the light, and then ran up to push him overboard. I got him into the water, but he grabbed onto me so I just went in with him. As I fell I could see there was another guy onboard in the front, and it looked like they were trying to cut the anchor loose. So they were going to try to steal the boat!
I hit the water wrestling with this guy and tried to drag him down to the bottom, but he let go of me and I went under the keel and then popped up the other side to get up the ladder. Thats when I saw the dorsal fin slide past me and then I heard the other guy start screaming. So there was a shark!
I managed to get back aboard Altair, and then got the light which I dropped in the cockpit and blasted the guy in the front (they were looking at the guy in the water getting eaten) and started yelling my head off.
Maybe he figured it wasn't worth it, because he jumped back into the panga and pushed away, while trying to get the motor running.
Anyways, after that it was a quiet night. And since it is April first, I hope you were fooled.
