Re: Stus-List Right of way (ROW) discussion

[Hoyt, Mike via CnC-List]

It seems that Pilot boats use horn signals and that Container ships trump all 
vessels.

Last evening during a Wednesday race with 30+ sailboats in varying classes in 
light winds the Pilot boat leaving the harbour stopped mid fleet turned 
backwards and repeatedly sounded their horn for a period of minutes.  Have 
never seen that before.  I suspect is also not the last we will hear of this.

I doubt the pilot boat or ship would have had any patience with stand up paddle 
boarders either as we clearly know who is on the top of the heap in ROW 
discussions!

I took all the coast guard and power squadron courses and learned all the regs

learned from 35 years of observation is; nobody uses horn signals or flag 
signals and lawyers have the right of way, so never invoke right of way unless 
you are racing, always take steps to avoid collisions early, and don't ever hit 
a lawyer.

It seems to me that there are a number of people on this list who don't know 
the rules.  Perhaps it's time to read Chapman's "Piloting, Seamanship and Small 
Boat Handling".  The pecking order is:  rowboats (including kayaks, canoes, 
paddle boards), sailboats, powerboats.  Then there are exceptions:  tug pulling 
a barge moves up the pecking order; overtaking boat moves down the pecking 
order and I'm sure there are more.

Stus-List Gear, shaft positin, transmission, folding ---- RE: (no subject)

[Hoyt, Mike via CnC-List]

The two things I take away from this are that 1. YES - a geared folding prop is 
much better than a floppy Martec folding prop and that 2. a Martec folding prop 
should have shaft aligned such that the blades are horizontal so that they stay 
folded esp in light wind.

So if the shaft is aligned that likely means not in neutral.  Back to original 
argument

Persistence has an oversized engine.  3GM30F where all C&C33-2 and Frers 33 
come stock with 2GM20F.  Behind the transmission there is BARELY sufficient 
distance on shaft for the dripless shaft seal.  The coupling would have to be 
marked in order to know the shaft was aligned.  This is all well and good but 
which crew member am I going to convince to climb inside the cockpit locker 
(after removing any contents), unfasten the fabric separator between locker and 
engine compartment, wiggle in a contorted position to get access to the coupler 
and shaft?  It is theoretically possible for us to align shaft but in 
practicality is impossible.

Therefore the only real conclusion is to lose the Martec and obtain a 
Flex-O-Fold

Tom,

I put mine in reverse to stop the prop, then position the shaft so the blades 
are folded.  Then I put it back into reverse to lock them in place.
It's easy, especially if you mark the shaft position when the boat is out of 
the water.

Stus-List Kanzaki Transmission in forward or reverse while sailing?

[Jean-Francois J Rivard via CnC-List]

+ 1 on reverse while sailing specifically for folding or feathering props. 
 

 If you leave it in neutral or forward it will freewheel and keep it from 
folding.  I don't know exactly why it still freewheels in forward but I do 
know it does. 

As for fixed props, Yanmar is very specific: 

Advisory Number: MSA08-003:

DATE February 8, 2008 Dealers and OEMs
TO: All Marine Distributors
SUBJECT: Gear in Neutral While Sailing All MODELS: 

All Sailboat Engines 

We continue to get questions regarding the correct gear position while 
sailing with the engine OFF. This advisory is issued as a reminder; Yanmar 
requires that if sailing with the engine OFF (not running) the 
transmission shifter must be in the neutral position or internal damage to 
the gear or sail-drive will result. This damage will not be covered by 
Yanmar’s Limited Warranty. Please instruct customers and dealers who 
deliver the sailboat to the customer, of the correct (Neutral) position 
for the marine gear while sailing.

If the customer desires that the propeller shaft not spin while sailing, 
either a folding propeller, shaft break, or other suitable device may be 
used. However, Yanmar accepts no responsibility for the selection, 
installation, or operation of such devices. Please also refer to Marine 
service advisory “MSA07-001_Yanmar Sail Drive Propeller Selection” for 
additional information.

Re: Stus-List Kanzaki Transmission in forward or reverse while sailing?

[Garry Cross via CnC-List]

Good to know. On mine if I put it in gear I need to start the engine to get
it out as the pressure while still sailing makes the shift lever very stiff
to move to neutral and that can't be good for the mechanism. I do not have
a folding prop. With a spinning prop, while not as good as folding, the
drag should be reduced somewhat as opposed to having it not spin.

Re: Stus-List Kanzaki Transmission in forward or reverse

[Dave Syer via CnC-List]

I believe, because while sailing in fwd (dragging the prop along)  there is
"negative thrust" on the clutch cone bearing surfaces, allowing the clutch
to slip.  (when powering, the prop is instead pushing forward, loading
those surfaces)In neutral, the clutch cones are centred, freewheeling,
 and are not engaging their mating surfaces, and in reverse, the mating
surfaces are engaged as they would be when actually powering in reverse,
with the prop's drag actually increasing the pressure on the mating
surfaces.

At least that's my theory... until corrected.

Mine rotates in fwd and neutral, not in reverse.

Dave

Re: Stus-List Gear, shaft positin, transmission, folding ---- RE: (no subject)

[Bruno Lachance via CnC-List]

Mike,
 
I will get back to you tonight with the price of my Flexofold 3 blades. It was 
not chead and i remebered i had to pay a ridiculously high custom clearance fee 
to UPS, I hate them since.
 
I was convinced to go 3 blades after reading a lot about prop balance and 
vibration. It is more expensive, but i went for it and i am very happy. I have 
less vibration than with my old fixed two blades.
 
It stops the boat quickly in reverse with minimal prop walk and i achieve 
target speed at low rpm, wich is good on fuel but i know it can lead to carbon 
buildup. To remediate that i do push the engine sometime but over 2800- 2900 
the engine is loaded and the black smoke comes out. So instead i push it in 
neutral at the dock. I remember some recommandations from Yanmar on this. 
something like: high revs for a moment to burn everything and then iddle to 
cool down the engine and then shut it off.
 
I do still think that my prop is bit too much for my small engine. And if i had 
to buy another i might go with a two blades instead because everybody seems 
satisfied with it.
 
 My prop would be perfect for your 3 GMF! ;)
 
Bruno.

Re: Stus-List Gear, shaft positin, transmission, folding ---- RE: (no subject)

[Bruno Lachance via CnC-List]

For me it was a priority to buy a nice prop.
 
I was loosing sleep over the drag of my old fixed prop to my boat that i wanted 
to race, and was also going crazy earing the prop free spin underway. I had to 
do something and choose a Flexofold that was cheaper than a maxprop.
 
My flexofold will spin in neutral, so i put it in reverse knowing i am not 
causing any arm to the transmission.
 
I prefer to spend my money on nice sails that i can see and enjoy, but a good 
prop is also important in my opinion.

Stus-List Gear, shaft positin, transmission, folding

[Daniel Sheer via CnC-List]

I like my MaxProp 2 blade. Instant bite in reverse, better than a fixed prop. 
Feathers easily. Leave the gear in reverse. Maybe a little more drag than 
folding, but it works well. Also, it's adjustable, and I've been able to 
maximize my engine performance over the years (got to be out of the water to 
adjust the pitch). Dem's my 2 cents.

We heard that from our side of the harbour.

Were boats actually in the way of the container ship or was the pilot boat

It seems that Pilot boats use horn signals and that Container ships trump all 
vessels.

 

Last evening during a Wednesday race with 30+ sailboats in varying classes in 
light winds the Pilot boat leaving the harbour stopped mid fleet turned 
backwards and repeatedly sounded their horn for a period of minutes.  Have 
never seen that before.  I suspect is also not the last we will hear of this.  

 

I doubt the pilot boat or ship would have had any patience with stand up paddle

Re: Stus-List Right of way (ROW) discussion

[robert via CnC-List]

Rick / Mike:

I think we have an over zealous 'Pilot'.Last Summer, I witnessed 
something quite unusual.an out going 'pilot boat' around the Point 
Pleasant Shoal mark turned around and blasted a sail boat in the path of 
an outgoing container vessel which was still back by George's Island.  
In no way was the sail boat going to impede the container 
vessel.there was plenty of time and plenty of room for there to be 
no issue.


Nevertheless, the 'Pilot', in my opinion, was harassing the sail boat.

Mike, on the other hand, some years back, a sailor from our club with a 
Tanzer 26 actually broadsided a container ship in the same Point 
Pleasant shoal area during a Wednesday night race.  Yep, it's not BS, I 
personally witnessed it and could not believe it actually happened.


Needed to say, the Harbor Master sent our club a nasty letter and 
restricted out Wednesday night racing to the far west side of the harbor 
for the remained of the season.  Hopefully, the Harbor Master won't be 
involved with last night's situation.

Re: Stus-List Right of way (ROW) discussion

[Sam Wheeler via CnC-List]

I had an exciting freighter experience this past weekend.

I went for a leisurely sunset sail with a couple of friends on Saturday
from San Francisco (where I had parked the boat for a few days) across the
bay to Emeryville (where I am permanently berthed).  We were probably about
a half-mile south of the Bay Bridge when a cargo ship came under the bridge
and turned to port, east towards Oakland - a course that would cross well
ahead of us without ever getting close.

About a minute after making the turn east, the freighter made a sudden
starboard turn to the west, which put it on course straight for us.  The
wind was light and we weren't moving very fast, but our course was
perpendicular to the ship's, and I figured we would probably pass ahead of
it at this point.  But it continues to bear down on us - those things
always move faster than I expect - and blows a few horn blasts, so we
scramble to fire up the engine and open up the throttle.

With the engine going strong, we're in good shape to get out of the way.
All clear, we start to relax and laugh about the situation.  Then the cargo
ship alters course again.  At first I think I'm imagining it, but it's
turning steadily to port, apparently tracking us to stay aimed straight at
my boat, and continues to close the distance.

So I hand off the wheel and run for the radio.  Hail "unidentified cargo
vessel" (hard to read a name when it's coming straight at you) on channel
16, and the Coast Guard helpfully tells me that ships only monitor 13.  Try
again on the right channel.

The pilot responds right away.  It turns out he's just turning in a circle
to drop anchor.  No danger, he sees us, and we're fine on our course.  We
shut the engine down and had a nice sail the rest of the way.  (Here's a
video  of the post-freighter portion of the
trip.)

Takeaways:
(1)  Count the horns.  My guess in retrospect is that he blew three to
indicate that he was in reverse and starting to slow down, not five for
"get out of the way if you don't want to be a smudge on my hull," which is
what I took it as.

(2)  I need get myself a handheld radio that I can use from the helm.

For most marine gearboxes the output flange

At least that's my theory... until corrected.

Bruno, did you find there was less vibration with the three blade prop?

Re: Stus-List Propeller - flexofold

[Bruno Lachance via CnC-List]

Yes, compared to the old fixed 2 blades. But maybe that old prop needed to be 
rebalanced, who knows. My prop shaft is aligned with the keel. I believe the 3 
blades makes a difference there. There is always a blade that has less 
turbulence from the keel. At least that is was I found as an explanation on the 
Web and it makes sense to me. But I don't have enough experience with different 
setup to really make a good comparison here.

Last year I decided to replace the cutless bearing and install a PSS. I ended 
up cutting the old shaft, replace it with an Aqualloy one and add a new Buck 
Algonquin split coupling. I also removed carefully the shaft strut and rebedded 
and fair it. I was lucky to be ok with minimal alignment of the engine after 
that. I hope to be fine for many years to come now. 

I also redid engine compartment insulation last year. It's not as quiet as an 
Oyster ;), but it is quieter and it runs smoother than before. I can't exactly 
identify the main reason since I changed everything at the same time.

Re: Stus-List Propeller - flexofold

[Josh Muckley via CnC-List]

That's less than half what the MSRP on a comparable Max-Prop would be.
That being said, I like my Max-Prop and would generally only consider a
Gori in its place.

Someone here has advised of a feathering prop which doesn't need the pitch
adjusted?  Kiwi-prop?  I can't remember.  I was quite intrigued by this
option as well.
