St Francis 44 propellers

[Bjorn Havemann]

Hi,

I have a St Francis 44ft Catamaran with 2 x Yanmar 3GM30-YEU motors and SD20 saildrives - a fairly standard configuration for these yachts. The 2-blade propellers I currently have achieve around 5 knts in calm conditions at around 2300-2500 rpms, which is quite slow. I would like recommendations on fixed blade (folding just too expensive) props that will give me better speeds at lower rpms as I am heading to waters where motoring is going to be frequent.

Thanks,
Bjorn
