Wow, this is great data.
But I think there is a question yet unanswered: How significant is the drag of the prop compared to the drag on the hull?
I'm sure there must be good data somewhere on the drag of typical sailboat hull shapes and lengths.
I played with this the other day in light air. I have a 33' Newport. At a speed of about 2 kts it seemed that it slowed our speed by about 0.1 kt by putting the transmission in gear vs. free-wheeling. I only played with it two or three times. Hardly statistically significant data.
I also had the boat serviced last weekend and discovered the transmission dipstick was missing from the plug! Has anyone heard of a dipstick falling off the threaded plug? Is there room in the casing for a loose dipstick? I'm planning on contacting the local Hurth dealer to get a new plug (with dipstick) and asking his opinion on the forward, reverse, neutral issue.
Thanks for all the information. I love this forum.
