Tony, Sail and Yachting Monthly reviewed a host of props of all different types under different load conditions running forward and reverse a few years ago. The one that surprised everybody including the testers was the Flex-O-Fold two blade folder. It performed as well or better than their three blade and many fixed props from what I remember. 

I purchased an Australian Slipstream Seahawk stainless steel three blade folder prior to the article because the Canadian dollar had tanked and I could not afford a European prop at the time. My original prop was too small, preventing the engine from warming up or the boat achieving 4 knots going downhill. The Slipstream does everything I could wish for and been in service for several years. My reason for opting for the three blade was due to having a tricky dock to enter or leave. The boat has performed well at the 2014 Nonsuch Rendezvous and in PHRF races 

Ben Hawke was excellent to deal with and was able to match the prop to my Universal 16 engine. I thought it was a minor miracle since my diesel was at least 25 years old at the time and he was not familiar with the engine or Nonsuches.

Planning to replace my fixed 3-blade prop with a folding prop. I'm likely
to go with Gori, and wonder under what circumstances I should want to spend
so much more for the 3-blade prop ($4,000) vs the 2-blade prop ($1,200).
 
We sail Sheba (Nonsuch 30C, #212) out of Nyack, NY on the Hudson River. I
started racing regularly again in 2016 in the non-spinnaker PHRF fleet, and
hope to improve my performance in 2017 (hence the quest for less propeller
drag). Most of my other sailing is daysailing and a couple short cruises
each season(2-3 days). I tend to single-hand often, so efficiency in
reverse is handy when docking and mooring alone. I'd say 90% of my sailing
is day-sailing and racing, with little motoring or motor-sailing (though
when going long distances I do both).
 
Would be curious to know opinions of other Nonsuch sailors, especially
those who have used Gori 2- or 3-blade folding props. Also, in addition
to difference in initial price, are there any significant differences
between the two Gori props as far as trouble-free operation, maintenance,
fouling, or durability?
 
Thanks for any opinions, guidance, or suggestions.

Interesting 2008 article comparing different props for drag, and for
performance under power, based on tank tests. Includes all 3 Gori models
(2-blade, 3-blade, racing 2-blade), plus other popular models like
Flex-o-Fold, Variprop and Autoprop.

I have a 3 blade flex-o-fold folder on my 33.
Minimal drag and great performance in fwd and reverse.
 
Look into it

When we purchased our 33, on board was an uninstalled Gori 2 blade. A call to the Gori dealer revealed that it was sold for a Nonsuch 33, with a 2003 Volvo rated 28HP@3200 rpm. My boat is a Universal and does not appear to have ever been modified.
Anyway, we have a Gori, seemingly in fine shape. The dealer (very preliminary) said the we might be able to change the blades but we’ll probably sell it.
Quite a mystery for us.

Tony,
PYI which sells Maxprops, says that the three blade prop will work better
powering against waves and wind and will be smoother than a two blade prop.
They do not
provide any data on this. They do suggest that a Maxprop will provide an
average 10 to 15% increase in sailing speed over a fixed prop. The effect
is most noticeable in light air.
 
I believe in the PHRF rules your rating will be changed when you go to a
feathering or folding prop.
 
I do not have experience with the Gori prop so can't help out with your
questions on that front.
 
On line you can find a comparison test of props conducted by Yachting
Monthly which is an interesting read.
http://www.yachtingmonthly.com/gear/folding-and-feathering-propeller-test-29807
 
Following the publication of the test the makers of the Kiwi prop had a
letter exchange in which the makers of the Kiwi prop criticized the test
methodology. They felt that Flexofold had gained an unfair advantage by
sending too big of a prop and that while it preformed well in the test the
larger proper would potentially damage the engine if used long term.

No-See-UM Mosquito Netting Bought it from Seattle Fabrics. I have seen
it done in white but white blocks the sun and view more than the black
does. So I used black.

Weight and binding tape for the weights from Bug Buster. I used half the
recommended weights and it works just fine.

Measure across the bimini and from front to back across the dodger and
bimini and add 12 inches to each measurement. Make the screen a square of
the largest measurement. Making it square means no fiddling with side to
side or front to back. You could make a rectangle but would need to have a
easy way to identify front from back. When the bugs come out time is of
the essence.
 
The fabric is 54 inches so the panels are french seamed together, I did it
in the basement as there was room to lay it all out. I have 4 panels on
our 26 and used Tenara thread so it is uv proof. I sewed it up on my
Bernina.
 
I have sailed in 15 - 20 K and no problems other watching that the sheet
does not get tangled when adjusting the sail. We can sit out after sunset
and be bug free as putting it up and down takes a minute. I stow it in a
nylon draw bag about 24" round made of old sail cloth.

Debbie,
Thank you for the tips on the bug screen. I did not know that white blocked
the sun and view more than black.
 
For La Reina we went with the low end approach. At a store called Ed's
Linens we bought a double bed sized mosquito net. It came with a hope that
we do not use.
Nesta sewed some coloured beads on the entry so we could easily find it
when putting the net up. I use a small carabiner to hang the net from one
of the lazy jacks and then we use clothes pins to hold it down.
If we plan to use the barbie for cooking I put the opening at the stern. It
stores in a mess bag that used to hold a
pair of bedroom slippers.
 
We have had it up in about 15 knots of breeze but it can not be up for
sailing. We have found that it does block the breeze to some extent so it
makes the cockpit a bit warmer. It proved its worth when we ended up in the
middle of a mating flight of flying ants.
 
I have attached a couple of photos.

Good morning,
 
Can anyone tell me the amount of transmission fluid I can expect to to draw
out from the Hurth HBW 100 and the total capacity. I have a topsider oil
changer but wonder if there is a better pump for the ATF.

I am preparing my 30C for a trip north and rather than deal with all the bridges and narrow passages in the ICW, I am planning to go outside at from Ft. Lauderdale at least to Georgia and maybe to North Carolina before entering the ditch. I am not planning to get too far off the coast but I am looking at all my options for safety. 
Do any of you folks carry inflatable lifeboats onboard, and if so how/where do you stow them?

Hi Phil;
 
We rented a 6 person self inflating raft for the Mackinac race last year. It was packed into a cube ~16 to 20” on a side a fit nicely under the table in the cabin. Out of the way, and reasonably accessible if required.
 

 
Rental details are probably not of interest to you but here they are anyway.

Phil: I’m not sure if you mean an inflatable dingy or life raft. I believe that auto-inflate rafts are available for rent, possibly through West Marine or others.

Best choice is the Winslow SLRR, super light rescue raft. Comes in different sizes and storage valise fits anywhere.
In conjunction with a 406 MHZ Epirb, you are set to go.
I have a small Ditch bag attached to my raft, and would be happy to let you know what is in it, if you are interested

Ralph, the original equipment winches for the Nonsuch 26 was a Barient 8
for the mainsheet and a 19 for the halliard. On Mascouche they were both
self tailing. My 8 was getting tired dealing with the main sheet so I
retired it to the cabin top to replace a standard 8 used for reefing or
choker. and got a good deal on an Andersen 28 to replace it. It is a super
winch which is smooth as silk. I would not hesitate to use one for the
halliard too.
 
I believe you would find the 8 too light to use for the halliard and the
original 19 is obsolete. Its parts impossible to find. I replaced mine with
a Harken 42 when they were selling off the old model. It is way overkill,
but it will outlast me. The first time I used it the effort was far more
than the 19! I realised that I had refinished the cabin top and the camber
was sufficient for the halliard to come into contact with it for a few
inches when taught. It was a very effective brake. A second eye further aft
solved the problem.
 
Cheers,

are not the bumpers essentially dock-bumpers? A quick look at West Marine
does not turn up an exact replacement, but close. I would do an Internet
search for dock bumpers or such and see what you find.

Lloyd,
Yes, that's exactly what they appear to be. I was hoping someone had identified a source for a close match.

I have the same problem and am looking for a solution. How about a cam
cleat behind the winch? You could drop the halyard into the winch each
arm's length and at least not have to let go of the winch handle to go hand
over hand on the halyard. I guess the other ($$$) solution is to replace
the winch with either a self-tailing or electric winch.

Hello Art;
 
I in fact have a line stopper in front of the winch. This means that I can
at least let go of the line to preposition my hand as I am tailing, but it
still means I am pulling with one arm while cranking with the other.
 
In an ideal world I would simply buy a self tailing winch; but I have a lot
of fixing to do on the boat and a definite budget. If I can reallocate
existing assets for no additional cost that is the way to go. In a few
years I may spring for an electric halyard winch, but it isn't in the
budget right now. The line stopper was a great addition though. If you
don't have one I would recommend it.
 
 
FYI; I'm an old Nova Scotian myself.
