I have a Catalina
30T. 1990. Went aground early in this past season and chewed up the bottom of the rudder
also has some signs of delamination
in a couple areas, so I am looking at an overall repair.
I have seen some information about a more optimal rudder shape, both cross section (NACA 0012 airfoil) and profile (leading edge curves aft towards the bottom of the rudder). This reportedly improves weather helm
, pointing ability and ease of maneuvering under power.
Anyone have any thoughts on this? Anyone have any plans?
I am not opposed to reshaping the rudder - I believe the most crucial tasks will be building a jig to hold the rudder in a proper position, and also aligning the rudder properly with the centerline of the shaft. I know I can also make a jig to use my router to create the NACA 0012 profile. And I can do it for a lot less $$ than a new rudder.
Or, I can just repair the rudder in its current
Thanks in advance for any input/advice!
