    Hello

    I have a request to build a fairly large GRP hard top with a dimension of aprox. 8.5 feet wide by 10 feet long. For a 42 foot flybridge sportfisher. It currently has a bimini top.

    It will need to support the weight of a 250 lb man and have a variety of items screwed into.

    Can some one give me the aprox. weight of a foam core and glass top with adequate strengthen to support being walked on top of. And the recommended material and glass schedule

    How to deal with the unknown locations of the many antenna, radar, sat dome, lights, observation hoop that will be needed to be installed into a foam core.

    Thank you
