F1 - I have a lounge seat like yours on the port side. I hate that damn contraption. It is starting to rust and it stores dirt and leaves and crap. Also it is a PITA to get to the fishbox beneath.

You should look at my seat pics in my gallery. The helm seat is a seat in front, and in back it is a cushion on a hinged lid to the livewell beneath. This is a nice setup, because it allows easy access to the livewell. Unfortunately, the space under the helm seat is inaccessible dead air. It would have been nice if the livewell had run under both seats, like the fishbox on the port side. I may cut a hatch into the bottom of the helm seat to reclaim this space for handy storage.

When my port lounge gets a bit more beat up, I think I will change it to a seat like the one on the helm side.

Just some food for thought. Love that full transom ya got there, and the blue tint is cool too. 8)
