sportfishing boats with high towers?

Before or after the addition of the extra weight...or are you comparing the now and then (the roll period then and the "doesn't snap roll" now?)?

PS: I'll do a bit more research...(From "The nature of boats"(Starting at pg 105 "Heave Ho")...invest... it is a good buy!)

I'm pretty sure the 6 seconds was after adding the wieght. If memory serves, the increase in period (before/after) was minimal (less than 1 second if my crude measurements/process was accurate).
