Can anybody tell me how to get behind or on top of the boathouse, or get Bobby out of my way so that I can reach the end of the dock?

I have earned pyrokinesis, telekinesis, invisibility, marksmanship and levitation badges.


I have tried everything I can think of and still can't reach the back of the boathouse, or the roof, or get rid of Bobby.

Use your levitation ball and jump up op the boathouse on the left side. Or use you levitation ball and go to the back fo the boat house and you will see some jumps.

Can someone please be more specific?
I tried standing at various places on the walkway by the left front corner of the boathouse, and the rock beside it, and aimed for the green roof and the rope netting, but can not get onto the roof. I've touched the roof and slid off lots of times, or gotten good height but off at the wrong angle, etc...

I have the PC version, with the latest patch.

I even tried gliding from the platform to the right coming down the stairs (where there was a PSI card) like it said you could do in an XBox walkthrough, but couldn't get nearly enough distance.

Never mind. I decided to skip this and do it at night, when Bobby wasn't blocking access to the rest of the docks.

BTW, the brain tank fight is a pain if you forget about the Palm Bomb upgrade.
I tried the fight a couple times, then quit the game because it was too tedious. Then I remembered about the upgrade, started the game again, and the first time I jumped to start a Palm Bomb, the game popped up a message about hitting the attack button repeatedly in the air to increase damage). arg... After that it was a relatively easy fight.
