Boron has also been used in some rockets as an ignition source. Boron-10, one of the naturally occurring isotopes of boron, is a good absorber of neutrons and is used in the control rods of nuclear reactors, as a radiation shield and as a neutron detector. Boron filaments are used in the aerospace industry because of their high-strength and lightweight.
The trailer is the big variable here, but the my 20' pontoon boat weighs about 1600 pounds with all the furniture on. The trailer will probably weigh about 1600-1800 if it's made of steel, so about 3200 lbs is probably about right.

While when we talk about pontoons, we are almost always referring to pontoon boats, the buoyancy of pontoons allow them to be used for a wide variety of uses. A pontoon is a device that can take on various shapes that is buoyant in the water and can be used for practical purposes to support a various amount of weight.
