Boat pulls right, what can it be?

Update-

Adjusted snout again, and it's much better. Might still be pulling a bit, but it's definitely better.

Thanks for the advice.

Jimbos explanation was spot on.. just to add here, prop plane pilots have the same issue ! During takeoff the plane will naturally pull to left because of the prop spin. So during the takeoff roll the pilot applies some right rudder to counteract the force. The more you know!
