• Parallel 1: Get to the captain's cabin after 4:30
• Parallel 2: Get to the captain's cabin between 3:30 and 4:29
• Parallel 3: Get to the captain's cabin before 3:29
• Parallel 4: Automatically follows parallel 3
• Parallel 5: Get to the captain's cabin between 3:30 and 4:29, but lose the fight

Next stand by the edge and let one of the green balls knock you into the water. When Jack helps you out you will have 0HP but you will still be alive. Ask Jack twice to refill your life and you will have between 10 and 30 HP. Go back to the green balls again and it will drop your life down to 75 from 80. Then refill your life again (do not use the meat). If you had 10-19 then when you go back to the menu there will be all of your new BH points! If you had 21-30 then just get hit again and refill then all the points will work! Go ahead and fill up to have a maximum of 200HP instead of 80HP!

Note: This trick usually works the first time, but if it didn't, go to another fight, earn more points and repeat the steps.

THE SHORT WAY AROUND

After entering the room with Musashi in the cage and the 'Record Kaiser in the upper corner climb up the stair. You will end up in the room with the rotating boxes on the platforms. Instead of climbing up the ladder, try this:

On the right side of the room you see a tan coloured box. Move it away by hitting it with your sword twice. You reveal a hidden passage. Jump into the hole to find yourself back in the 'Musashi Room' on top of some cages. Enter the doorway left of you to leave the ship. Jack will give you some advice because he is concerned about some shark or so. Ignore him turm to the right and follow the passage outside and around the ship. It will take some jumps and ladder climbing but then you are at a place which seems to be a dead end. Simply cut through the rope at the right, then jump down. Climb the ladder and break through the door by hacking at it three times. Jump into the hole and now it takes 7 more jumps and you end up in the room just underneath the ships deck.

Taking this way saves a lot time because it avoids the nasty rotating platform and the room with the crane where you are supposed to play wrecker. I was able to manage the whole way from the start to the captains cabin in under 3 minutes.
