Hello, this is my first post on this forum. I have a 16ft. Jon boat and the floor is 52" wide. It is a mod-v style. I have very little carpentry skills and I need some help. I want to build a deck that is inch lower than the edge of the boat. The front deck that is on the boat is only about 1.5' wide (barely enough to stand on) and it is six inches higher that than the bench behind it. My question is, how do if measure to find out how high I need to raise the deck over the bench to make it about 1 inch lower than the bow edge of the boat. The front deck that is is on it is also 3" lower than the bow edge of the boat. I hope this makes sense.
