Rudder splicing

Postby Jaap » Sat Feb 20, 2021 9:46 pm

Dear All,
The temperature is rising so I started to prepare my boat for the season. During cleaning I noticed a splitting of the rudder. It seems like the paint is cracking over the middle downwards. At the bottom on the back there's also a crack. Does anybody know how the rudder is made? Is there a wood core? Or is it polyester glued together?
I'm thinking of opening up the crack and then try filling it with epoxy. Any other thought would be appriciated!

Afterwards a bit of paint, does someone know the RAL colorscheme of hull and deck?

Thank you, greetings,
JaapImageImageImage

Today i removed the rudder to take to a grp specialist. I've contacted honnor marine and that was their advice. It looks like no wood is used in the rudder. I hope so, when moving the rudder i could hear water inside.when turning upside down it came out.
I think the reason of the tear could be because the helm is only fixed with one bolt. When steering forces on this bolrt may be responsible for torsion.
I thought i saw a rudder on the forum with a large plate on both sides to dispers forces.
I going to look into that.

The rudder is constructed in two halves and several owners have reported cracks appearing between the two. Mine showed a crack on the trailing edge at about waterline level, so I cut into the crack with a dremel and filled it with epoxy to seal. There was no water evident. Chris Wicks had more serious problems and a lot of water within. In the worst case a new one could be constructed either out of GRP or perhaps wood.

There is a whole thread named Rudder Problems covering these issues. Kaliope has always had some rudder problems with various repairs over the years.

I copied the plans of Ian (a previous owner of Ladybird) and successfully fitted stainless steel reinforcement plates. The water still manages to get in the rudder somehow during a summer afloat, but the reinforcement plates are very good. I have added a link to the album above.

Henk who has Dipper also had a similar problem with his rudder and is currently having the same reinforcement applied to his boat.

Cheers,

Chris

Thank you for your answers.
I'll try to reinforce the rudder as shown by others. If it worked I'll post new pictures.
