What is the difference between a 2 and 3 blade Flexofold propeller?

When choosing between a 2 and 3 bladed propeller there is a very small difference in drag reduction. The main difference is the performance under power where in calm conditions the 2 and 3 blade perform almost the same (in fact the 2 blade has a very small advantage in calm weather).

However, as resistance on the boat goes up a 3 bladed propeller (more blade surface area) slips less and maintains better boat speeds. This is why we also manufacture 4 and 5 Blade propellers.
