Rudder foils

I have a medium weight cruising cat. 37ftx 20ftx2ft 9500lb cruising wt. The stern tends to squat a little when sailing at cruising speed (6-10 knots+-)
The question is would adding foils say 2ft wide or so to each rudder help reduce the squat at this speed range.
If so are there any suggestions for the foil shape ??

 

Arse dragging is SO annoying. And can be rectified so easily with just about any shaped inverted T setup on rudder. Here's what I use on Frog - which is proportionately the same as on my other larger 8.5 metre (second image) tri foiler. My lifting sections are asymmetric and set at zero degrees angle of attack.

 

Moving weight forward might be easier.

 

You mean reduce weight don't you?
But this is a cruising/overweight? multihull question.
Re-ballasting/shifting weight forward just sticks the nose down.
Ever sailed/tacked a bow down multihull?
There is no easy answer ... except rudder foils will lift the arse up.

 

I agree there is no easy answer.
Yes, I have sailed a Cruising cat bow down as an experiment to see if it helped.
It got the transoms out and added .2 of a nt at 7 kt's boat speed.
Tacking was slightly slower.
