How to put a flat floor in a deep v boat

A V-bottom boat is a common design and produces a good ride in rough water because the pointed bow slices forward through the water and the V-shaped bottom softens the up-and-down movement of the boat. A major disadvantage of a V-bottom boat is that it is difficult to move around in because the bottom floor is not flat. With a few materials, you can modify the bottom of a V-bottom boat by installing a floor, which allows for easy movement within the boat without changing the outside appearance of it.

Skill level:

Things you need

  • 1.5-inch decking screws
  • 2-inch-by-2-inch-by-8-foot treated lumber
  • 4-foot-by-8-foot-by-1/2-inch marine-grade plywood
  • Reciprocating jigsaw
  • Circular Saw
  • Portable Drill
  • 16-foot steel measuring tape
  • Scissors
  • Cardboard
  • Paint
  • Carpet
  • Pencil

  1. 1

    Measure the width and length of the boat using the 16-foot steel measuring tape. Start at the rear of the boat and pull the measuring tape to where the nose starts to narrow toward the bow to find your measurement.

  2. 2

    Cut the 2-inch-by-2-inch-by-8-foot treated lumber with the circular saw to fit the width of the boat. Place one piece every 2 feet of the length of the boat. Since boats come in different sizes, you will cut the lumber according the width measurement you obtained in Step 1.

  3. 3

    Cut marine plywood to the desired length and width from Step 1, using the circular saw. Lay the plywood flush on the 2-inch-by-2-inch treated lumber supports. Attach plywood to the supports with 1.5-inch decking screws using the portable drill.

  4. 4

    Determine the correct cut for the bow by cutting a piece of cardboard and trimming it until it fits from the back decking to the bow. This will be used as a template to cut the piece of plywood to form the decking for the bow.

  5. 5

    Lay the template on a piece of marine plywood and trace it using the pencil. Cut out the bow section from the plywood using the reciprocating jigsaw.

  6. 6

    Attach the bow section to the 2-inch-by-2-inch braces with the portable drill and 1.5-inch decking screws.

  7. 7

    Paint or carpet the deck to protect it from water and to give it a finished appearance.

Tips and warnings

  • Limit the material to prevent excess weight in the boat.
  • V-bottom boats may become unstable, so limit movement inside of them.
