anchor, chain size calculations

[cszosler]

at the present I own 32' mono and ground tackele was chosen using tables, it worked well. I'm planing to swap for 32'catamaran. Will it be correct to use same table for cat. Or shall I multiply sizes by 0.5 or 1.5 or other. I'm aware of the difference between those two hulls, so no education is reacquired. Thanks in advance.

Assume the catamaran is lower displacement than the mono but the catamaran has greater windage. Seems to me they would need the same size ground tackle.
