Dual Rudders & Clearing Kelp?


Recommended Posts

For those with experience on dual rudder boats, what are your best tools and techniques for dealing with kelp and other debris?

Of course, we try to avoid it, however quite regularly we get kelp and other debris stuck on the shaft in the gap between the hull and the rudder. 

Been thinking about two angles of this:

Prevention - a small fixed, reasonably sharp fin in front of the rudder/hull gap which would either cut softer materials like kelp and grass, or deflect it away from the shaft and down to the rudder where we can clear with kelp stick.

Removal - some sort of modified kelp stick which might allow us to cut, push or grab the kelp to get it off the rudder shaft. Don't really know how to create this or where to get one since most kelp sticks are just for pushing down the leading edge of keel.

 

So... What are you using?

We use our hands, but you 'll lose some time. Especially anoying during race start.
You can't leave and the rest is taking of. This was in Nacra catamaran Class.

The Sunfast 3600 has a stainless blade to try and keep weed off the top but for the whole rudder we have a weed stick. A mould was taken from a rudder to make a 2” wide arm in carbon that is lined with seadeck foam, this is bonded to a carbon stick and that’s what we use. Other people have used a bit of stainless rod wrapped in rope core and welded to a boat brush handle. The rod is bent into a curve.

JL92S... any chance the blade is not a custom item and you have a source for it? Trying not reinvent the wheel here.

You’d have to contact a Jeanneau dealer and see if it has a part number on the system
