Rent a dumpster that will be large enough to fit the cut-up boat hull. You can rent a dumpster from your local container rental service--they will deliver the dumpster to you and pick it up when it's full.
Remove anything that isn't fiberglass, such as metal fixtures or trim, from the boat hull.
Put on a respirator and safety glasses. Begin cutting the fiberglass hull in pieces small enough to be easily carried. Begin at the top of the hull and work your way down until the entire hull is in manageable pieces.
Put on thick work gloves to protect your hands from the sharp edges of the fiberglass. Load all the pieces of the hull into the dumpster.
