This old girl in the pictures is around 30 years old with original teak hatch slides and no kind of oil upkeep; now they're cracked, rotten, and nasty looking. I'm not one for doing upkeep myself, I've got a family to manage not details on a boat; so I picked up a solid composite decking board at a big box store for about 11 dollars to replace the old teak and hopefully never have to mess with it. Composite decking is a kind of plastic lumber; it just happens to be the right thickness for this project. I picked grey because that's all my area store had, but natural looking composite board would look good for this repair. 

Tools and materials needed:
circular saw
sander and paper
kitchen and bath caulk

Power tools are used for this project, follow all safety instructions that come with your tools.

Step 1: Remove the old pieces

Remove all the old wooden pieces remembering left and rights, this is important for lining up screw holes with the new pieces.
