    ° have a mass minimum of 25.0 grams
    °the weights when loaded into the boat must be open to air

    You could use aluminum flashing to build a boat. You'd have to cut it and seal the joints with caulking material but you could design a really cool boat with it.

    Alternatively you could use paper and spray it with some water repellant spray:

    or

    You could investigate ship designs and create a model patterned after one like the tumbledown design:

    It's not clear how much you expect the boat to carry. In any event, you can make a simple box which will float.

    You can fabricate the hull out of sheet styrene plastic which can be cut and glued together. If the hull needs local strengthening, you can construct internal framing from styrene sections.

    Done right, you can make a fairly sturdy hull without too much effort.

    the boat needs to be able to hold 20 times its own mass

    You'll have to use this criterion to decide on the proper dimensions of your bote. (bote is the informal of boat)
