best folding prop?

The brand is a Kiwi Feathering Prop.

The composite blades are actually one of the prime reasons for the lower cost (compared to a forged blade) and the exchange rate helps a little. A replacement blade is $50 for comparison.

Since we knew that we were in the market for a prop change, we started keeping notes on perfornance under both power and sail over about six months.

We invested a couple of evenings doing speed runs on a measured mile (both ways) at various rpms. We tracked sailing speeds on numerous wind angles and wind speeds.

There is an older thread called something like "performance gains feathering prop" where I posted most of the detail. The short version is that
- under power we gained +1.5 kts
- under sail, most wind conditions +1.1 kts
