OK, so I'll concede that it only adds one more possibility of leaking, but other piece of the equation is that it is far less bouyant in a capsize.
And as for "stepping up" I will freely admit little knowledge with regard to history. Did they truly "step up" or was this decision forced on to them by lawyers? Matt, I know you've addressed this in the past here, but I honestly don't remember how that whole thing came about.
As to electrocution, I've often wondered how much additional safety is truly added by the comp tip. Many people sail in salt water. If it gets a little wet, I wonder how protected you really are? And, the mast tang and wires are still up pretty high. Here in MN, Xcel Energy recommends staying ten feet away because of the possibility of an arch of current jumping through the air. Not saying it doesn't make it safer, but I'm just not sure how much safer it makes it.
