A Challange

Until I get back to my boat, I thought I would throw out a challenge to you boat aficionados. A game if you like.
To the left is a piece of laser cut 6mm plate SS yet to be installed on my boat.
The challenge to my  readers is to guess what this SS piece is for and where on the boat it is located.
The SS requires two holes to be drilled in it for mounting and then it is finished.
Any reader may guess up to twice, and I will allow 5 questions from any one to help others guess as to  what and where it's for. So if you are going to ask a question, think carefully,  because you are asking on behalf of everyone. There are only 5 questions allowed. You may not ask questions related to Location or Uses. Sorry, there are no prizes. Have fun guessing. Let the game begin.
You may put your questions and guesses in the comments section below this post.
