Hello all. I have a beautiful new 34 foot advantaged off shore powered by twin 650 ilmore's. The other day I was making a moderate speed run at about 70 miles an hour in lake havasu. As I approached the buoy line I started to back off the throttles which caused the boat to start the porpoise a little. So I started to bring the trim on the motors in just a little to settle the bow. When the boat slowed to approximately 50 mph it instantly rolled onto the left side almost to the gunnel. Which almost caused by passengers to be ejected.
Obviously driver error is to be blamed. But can someone explain to me why the boat would react in such a way. I have never had a boat react to a change in trim so dramatically or violently so I would like to understand the process that caused the boat to react that way so that it never happens again.
Thanks for your time and your expertise
Robert

Are you sure that you didn't accidently put one of the Tabs or K-Planes down? That would cause just such a reaction.
