    Have built a new Teak wheelbox for my boat, and am now building the curved top.
    The top is ~22in. wide x ~35in. long, and has 1in. of rise in the arc of the curve.
    The top will be hinged at the back, and it offers access to the Edson gear, as well as serving as a hatch into the lazarette.
    I'm thinking of using some carbon fiber on the inside or outside, (maybe both,) of the curved top to increase stiffness.
    The top is 1/2in. Jatoba, installed as narrow edge-beveled planks with glued seams.
    Jatoba was chosen for its resistance to bending and impact loads,, such as when you stand on it, or, (heaven forbid,) drop an anchor or outboard on it.
    It will be painted, and sets in a rabbet of the exterior frame, which is Teak.
    What say some of you guys with knowledge of Carbon Fiber for an application such as this?

    There's little benefit of using carbon as opposed to standard E-glass. The wood will be stronger and stiffer than a single layer of any cloth you use.

    Glass both sides to prevent the seams from opening. Use what ever cloth is cheapest or on hand (other than matt)

    ^ Yeah, I think you're right; went ahead and got some E-glass for the job.
    As for the carbon fiber, it was one of those "I wonder if" times.
