He said 20 hours - that means, to me, 20 hours

If you were taking 20 hrs here it would mean you were taking 5 four hour
classes or some combination of them 4 and 3, plus lab time...the average
student carries 16 credit hrs per semester....plus labs and library time...

Kate,
Don't you think that someone who had 20 credit hours of physics and 18 of math
would know immediately that 200 gallons is a volume much larger than a
centerboard trunk? And after it was pointed out twice he claimed he didn't
have time to do the calculation!

roughly 8 gallons (64 pounds of water) to a cubic foot implies 25 cubic feet.
or almost 4 liters to a gallon implies 800 cubic liters or 0.8 cubic meters

either way good to about 10%, or just go to:

Or, if he had the sailing experience he claims, he would know that a 100 gallon
water tank is rather large, roughly coffin sized, and is bigger than what is
found on most smaller sailboats - 200 gallons is huge! Either Jim is a
complete fake, or he's just too slow and lazy to figure out anything on his own.
