Yes, I understand it's a cruiser. I have have the same boat. I was just curious if we're talking four adults sitting across the transom seat with a cooler full of ice and beer at their feet.
I installed a couple of pad eye's on the bulkhead for the Vberth. I move my coolers, roll up dinghy and honda 2k generator down below in the companionway as far forward as I can and use a ratcheting tie down to make sure nothing moves. That helps a lot.
Also, if there are people on the boat, then I have the heaviest people sit up in the front seat with me. I try to keep people off of the transom seating until the boat is on plane.
As soon as I advance the throttle, I also start trimming the drive out and the tabs down.
Admittedly, I don't boat with 5-6 adults on the boat. Our friends all have boats and when we invite non-boating friends, it's 1-2 people. I would assume larger tabs would help. I'd say away from 'whale tale' type fins on the outdrive. The is lifting the hull through the outdrive and transom assembly. Those components were not designed for upward force.
