    OK, I have a question. How do you determine the hight that you place your eye bolt? Is it a set distance from the shear/deck or from the bottom of the keel?

    I determined  the location on the Slipper by how it fit my winch and bow stop.
    Wanted the eye well above the hulls waterline to avoid leaks and low enough
    that the line of pull to the winch was slightly upward to avoid stressing the hull
    during retrieval and while sitting on the trailer. If the eye is too high, and the winch
    can't be adjusted to fit the location, then the tension created by the winch
    will pull down on the bow, causing a load that can hog the hull. I see that problem a lot
    on older fiberglass hulls. A download on the bow causing an upward bend in the
    line of the keel where it hits the forward roller.

    note the upward line of pull from the eye to the winch...

    Thanks Brett. I was trying to anticipate my eye location so that I could "flatten" the area of the keel to receive the eye bolt. I just don't know much about this part of the building process.
