Subject: Seamanship Question #15 Props
From: Jeff Morris Date: 11/26/2004 10:29 AM Pacific Standard Time Message-id: I'll take some of those points - It was me, not Neal, that pointed out that the gearing could well be different in reverse. I also pointed out that it would be easily noticeable. Curiously, his first answer, that the prop was mounted backwards, may have been a better answer. That doesn't change the handedness, but if the blade is not symmetrical it will affect the efficiency. Wish I had a prop handy. My own feeling is that different gearing is a rarity. However, props are designed to be most efficient when ahead, which means less efficient when astern, so basically I agree. Shen |
