I learned to sail in a 7-foot long sailboat that regularly achieved 20 knots.

One square foot is 144 square inches. So 20 square inches is much smaller.
It would be about mabye $200 or $100
about 400 pounds I just scrapped out an 18 foot sweetwater/godfrey pontoon boat. got 390 pounds of aluminum, at $0.40/pound yielded $156. 200 pounds was in the railings and deck braces, 190 in the actual pontoons. after disassembling, all most of the weight of the boat is in the plywood deck, the rest in the seats/upholstery
over 20,ooo dollars
Beer. Plenty of beer. And some sodas for the designated operator. You can kill someone or get yourself killed as easily on a boat as in a car.

20 inches are 1.6666666667 feet.
20 foot-pounds equates to approximately 27.1nM
Around 20 to 25 pounds per square foot.
