[Paddlewise] Upgrading old style Klepper rudder in Australia

Hi Paddlers,

I am keen to get some ideas for upgrading an old fashion rudder blade on a
Klepper Aerius 2 double.

The style I have (1970's) has an trailing alum. horizontal blade with little
"bite", particularly in following seas and /or whilst sailing.

My uses are loaded sea touring and sailing with Klepper jib and occasionally
a
S4 mainsail (without gear).

One thought is to upgrade the blade to a Balogh style "balanced blade" design
as indicated in Ralph Diaz's Folding Kayaker book.

If this approach what aluminium should I (thickness, hardness) use to avoid
bending or too stiff = cracking.

Another is buy a Feathercraft K2 rudder (about $A300 - $400 here) or the new
Klepper rudder system - like a Feathercraft (about $A200 - $300
here).Significant investments.

Finances lean towards having a go myself making a new blade using the
existing
rudder attachment fitting.

Any experiences with these options or suggestions?

How does a wider profile blade Balogh style perform vs a narrower and deeper
Feathercraft K 2 rudder blade profile.

Any other better rudder shapes going round?

Does anyone used stainless for rudder blades, if not why not?


Many thanks in advance
