Hey everyone, I'm new to the forums, and fishing, only been out for about a year and a half, Used to be land based but I recently aquired a 12ft clark tinny, It has 3 seats which make it really uncomfortable to stand up and move around, so I want to remove the middle seat and put in a flase floor, what kind of price would I be looking at to take it to a shop to have them remove the seat and put in new ribs and add some horizontal beams to support the floor?
