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.

1 A pontoon boat can range anywhere from 16â² to as large as 30â². 2  This is going to be the size of the deck. 3  A 16â² boat can hold up to six people, while a boat as large as 30â² can hold upwards of 15 people.4  The number of seats available will be determined by the size of the boat and the number of people it can hold. With a financing plan, many pontoon boat owners pay $200 to $300 per month over a few years. 2  While this will save you money up front, you will end up paying more for the boat because of the interest.
