I am wondering what happened to create the crack. Might it be from water freezing inside the rudder? If so you would want to make sure the water is removed and the source found and sealed.
I would definitely use epoxy. Dig out the crack. Fill with thickened epoxy and cover with fiberglass. You will likely then need to fair the rudder to maintain the shape on both sides.

Subject: [Rhodes22-list] Rudder Fracture

Hello All,

My rudder has a 3 cm vertical fracture along the trailing edge. It is about
0.5 mm wide.

I was thinking of ‘painting’ the crack with two part epoxy paste and then
painting the entire rudder with bottom paint.

Another idea is to fill it with some 3M marine product.

Any other ideas?

Has this kind of crack developed in anyone else’s rudder?

Regards,

Michael
