jeff, are you sure of that 25 to 35 pound figure at 7 knots? I recall 170# at
5 knots.

35# at 7 knots is only about 3/4 hp. not worth thinking about.

If you insist on calling the Autoprop "feathering" then you have to admit its
a
pretty poor one, having 5 to 10 times the drag of other feathering props.
For
example, in the MIT/Practical Sailor test, at about 7 knots the Autoprop had
10
pounds of drag, while the 2 and 3 blade Maxprop feathering props had about 1
and
2 pounds respectively. The folding props were so low they weren't shown. 10
pounds of drag is pretty good, compared to the 25 to 35 pounds for many of
the
props in the test, but it isn't the same as feathering. The Autoprop has
some
interesting properties, like very good performance in reverse, if you rev it
up.

it does not fit. not even close. and if you had not blown $2,200 on a

prop
hoping against hope you could make your boat *sail* faster you would know

the
difference.

Did the dealer tell you you could pass Island Packets and Westsail 32 if

you
bought an auto-prop?




I didn't buy one JAXAshby. I simply wanted to know what you meant by
calling it a non-feathering prop. Alas, I should have known better than
to expect rational discourse from you.
