Replacing 3 blade propeller. Recommendations?

Current 3 blade 13” Pitch unknown, has served Santé Tartan 34C well. Reverse out of slip into strong current & wind - no problem. Motoring home into the strong outgoing tide, strong head wind & chop at 5 mph - no problem. Beer Can Racing on light summer winds into strong currents with 3 blade offering much resistance - PROBLEM!
Considering an upgrade to a two blade folding by Flexofold or Varifold. Any recommendations or comments?

Nothing is more important than a beercan race. Definitely slip on a Max.

Re: Replacing 3 blade propeller. Recommendations?

I have a flexofold two blade on our boat and it works great. I have tested a three blade on a sister ship and found no real difference in performance. during docking I could not tell any difference but both boats have more thrust then you need in forward and reverse so it is hard to tell the difference. tested full speed in reverse only on our boat not the one with the three blade. during a side by side top speed test run we have a bit more speed with the two blade about a half knot. flexofold is simple and less expensive then many and requires almost no maintenance. change the anode about every 6 months.
