Hardly know where to start...My questions will be many as I am a complete novice at this.

I have a South Coast 22' with aluminum mast and boom. It has been out of the water for three years and brought it home to my shop for refurbishing. I can handle the brightwork but, will need some help with making her water tight.
The hatch for her companionway, which is fabricated of Fiberglas, is sloppy and very difficult to move fore and aft. I'm thinking I would like to rebuild it out of segmented cherry/walnut/maple. Does this make any sense?
A 4" hole was cut in the cabin top to make way for an air scoop that never arrived. I can turn a cover/plug for it and segment some maple and walnut to dress it up.
The forward hatch had a solar battery operated fan added by a previous owner and it never worked when I got it. I don't know if I want to try and repair, replace or remove and build a new hatch cover of wood.
