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.

Determining a deck size for your pontoon boat can be a difficult decision, itâs important to take into consideration both the amount of people youâd like to transport as well as the size of the body of water you plan to use the boat on. Generally, a 17 to 19-foot pontoon boat is best for small bodies of water that tend to be calmer. These boats are great for entertaining groups of up to eight people. 20 to 22-foot boats are well suited for lakes and rivers that do not have large waves. The mid-sized boats are well equipped to seat up to 13 passengers.
