Concept for radical water speed record rocket boat

Weight

Thanks for the comments. It's hard to imagine a 20 foot concept like Arvil's weighing much more than 900 lbs dry. The rocket Funny Cars were heavier than the dragsters and even they only weighed about 850 to 900 lbs. The red and gold car shown at the beginning of this thread only weighed about 500 lbs.

A tank two feet in diameter and three feet long will hold 70 gallons (812 lbs) of 90% hydrogen peroxide, enough to sustain 10,000 lbs thrust for about 9 seconds. With fuel and driver the fully loaded gross weight would be around 1,800 lbs, although this would diminish rapidly during the burn.
