Other modifications related to the transom bar are the cooler holder and/or shelf set into the engine well opening.
If the bar is lowered and designed for it, it can hold your cooler, getting it up off the floor and out of the way of your feet, although now it' more in the way of getting to the engines and to and from the swim step. Now the cooler helps you not fall out of the boat in your awkward moments, and you can grab another beer while you're there, too!
Turn the bar into a shelf, and now you have a bait cutting board, cocktail table, BBQ rack, cooler shelf, and a platform for firing ceremonial cannons, etc.
Make it strong enough, and you can also stand on it for viewing wildlife, doing camera work, or helping bring the dinghy aboard, etc.
