Question

To be considered safe for ocean sailing, the capsize screening value C should be less than 2 For a boat with a beam (or width) b in feet and displacement d in pounds, C is determined by the function C=4d^-1/3b.

a) Find the capsize screening value for the Tartan 4100 which has a displacement of 23,245 lbs and a beam of 13.5 ft.
for this one i came up with the answer c=1.89 this is how i got that please let me know if it is right
c=4(23245)^-1/3(13.5)
c=4(.035)(13.5)
c=.14(13.5)
c=1.89

now i have to solve for D how would i do that

Answer 1

They already gave d right?

Answer 2

23,245

Answer 3

So big D and little d are different things? Where do they mention big D?

Answer 4

C=4d^-1/3b I need to solve for d there are no numbers given

Answer 5

Well, what's stopping you?

Answer 6

Why not divide by 4? then b?
