The rudder change has been submitted to World Sailing for consideration. The ISCA Advisory Council approved a proposal, sent it to the ISCA World Council which approved the potential change, causing it to be eligible to be submitted to World Sailing.? The minutes were poorly written and should have stated implementation cannot occur until the proposal is approved by World Sailing.? That can take 1-1/2 to 2 years.?
Making the rudder blade more vertical is reported to make loads on the tiller lighter when it is windy, making less deflection in the tiller, lower loads on the rudder cheeks, easier to steer.?
In weedy locations may prove to be a problem.? TBD.?
If it is approved by World Sailing, watch for far clearer information and how to's, but it's going to be a while.
People who are good with tools will have an advantage.
