Downwind pole contol lines-replacement

david bruce
 

Hello, 
I am looking to create a new set of the blue,red,yellow downwind pole control lines and am looking for information about this type of line and it's sourcing.  Bills book calls it 'Tempest' but I can't seem to find any online references to this type of line and do not recall seeing it in any chandleries.   Does anyone know what brand it might be?   Also more generally is this type of line used for this application for any specific reason (besides the pretty colors) ie it's stretch or shock absorption attributes, making it important to replace like with like or less ideally could other types of line be used? 
Thank you

Bill,

There is no easy way to switch them.  The clevis pins are VERY different sizes, as are the holes in the chain plate.  If someone has enlarged the holes for the intermediate shrouds to the point where the upper’s pin would fit, and then put the smaller intermediate pin in the bigger hole that used to hold the upper, that’s a bad idea. I can think of no good reason for doing so.

Other than that, I can see no reason the position should matter one way or the other.  It is possible Amel wasn’t consistent, although this would be surprising.  It is more likely that Amel changed at some point, and you are seeing a model year difference.

For what it is worth, on #160 the intermediate is forward, and there would be no way to change that without modifying the chain plate.

Hi all,

just my small contribution to this topic:
Last year in spring our 54 was operated in the marina by the mechanics (without us by Covid) from the pontoon box to the travelift.The engine was used only briefly for propulsion, most maneuvers were apparently controlled with the bow stare, is also much easier and more efficient...Without generator. And back again to another place. 
Master Volvo was used only briefly for propulsion, most maneuvers were apparently controlled with the bow thruster, is also much easier and more efficient...Without generator and alternator. With battery power alone!
When we boarded in the fall all batteries were completely destroyed: < 7V per battery. No light no pump, nothing. The boat was dead.
the electrician kept a low profile and just said "bye bye". Since our batteries were otherwise always at 26.8 V when we came back after months. No proof, but 12 new Victron AGM for 4000 € were expensive port maneuvers. Never again without our company on board.

I agree that the action of turning on the generator and charger becomes excessive at some point. I think it is just a level of personal comfort, as to how much we are each willing to do, to avoid a potential problem. As for us, we do not turn in the generator if a few short bursts may be expected in an open anchorage.

I agree on the temperature current problem but this is important in difficult anchorages with strong side wind in normal anchoring is it justified? To know I have installed one Onan starter button in the cockpit as it is not convenient to go down to start the generator ….

Hi Dimitri;

I think the comcept of operating the bow thruster with the charger on, makes sense to me. The charger simply helps to keep the voltage to the bow thruster as high as the boat is capable, so the current draw by the bow thruster is minimized, again as much as possible, with everything our boats have at their disposal. Since the power required to run the bow thruster is a function of Voltage (V) x Current (I), the higher the voltage, the lower the current requirement.

Higher currents create higher temperatures and therefore lead to shorter usage time of the bow thruster before the temperature sensor shuts off the bow thruster. It is also less stress on all other functioning parts that have to channel the current to the bow thruster motor, including the motor itself.

There are very different views if it is good to run the generator and battery charger when using the Bowthruster despite the recommendation of AMEL. Perhaps Bill Rouse or other experienced sailors have to comment on that. If the batteries are well charged by the alternator of the engine and they are not very old I need a second opinion on that issue.

Hi Mohammad

I had the same problem two times. Every time, it was the solenoid on the bow thruster that did not work anymore.
If the batteries are weak and you use the bow thruster without starting the generator and charger, it can burn the solenoid. 
Every time it happened, the bow thruster worked only in one direction.

rigging question

william reynolds
 

 In our travels in the eastern Caribbean we have noticed that the rigging on the main mast on the SM's we see varies.  On our SM2k the intermediate shroud is forward on the chain plate and the upper is aft. On other boats we see the shrouds are reversed, the upper is forward. Can anyone confirm the correct orientation designed by AMEL?

Re: Bow thruster does not work in one direction

Mohammad Shirloo
 

Thanks to all for the quick and helpful assistance.

 

We did work on the Bow Thruster yesterday and it did turn out to be bad contact at the control box plug, which some CorrosionX (thank you Bill R for introducing us to CorrosionX a few years back)  and multiple plugging and unplugging, resolved, for now. Sometimes you get lucky with simply solutions.  I will have to order the control box, IPC relay, micro switches and maybe a joystick, as I believe, we may have to revisit this issues in the future.

 

Since we had the bow thruster cover removed, I did notice a squealing sound while the unit was being lowered and raised. It appears to be coming from the worm gear, but it is hard to tell. Has anyone  run into this and do you know if there is a way to lubricate this gearing and whether the motor for the up/down function needs maintenance?

As I reported earlier, our Group member, SM owner, Circumnavigator in a SM and International Space Station, Astronaut, and Professor of Cardiology, responded with the following advice:

Regarding motion-sickness treatments, I checked with my NASA colleagues, who wrote:
Phenergan (promethazine) is still the treatment of choice for Space Motion Sickness/SAS. As you know I first used it to treat a crewmate on an earlier STS flight and it became the treatment. Questions were raised if ondansetron (ZOFRAN) would be better.  Ondansetron was trialed on ISS (the Space Station); it was not as effective as Phenergan. NASA Flight Medicine thinks that Phenergan will remain the treatment for the foreseeable future because it is effective and that the actual side-effects experienced as opposed to what appears in the package insert have not been an issue.

As you are probably aware, Phenergan can be sedating, but the sedative effect can be countered by amphetamines or ephedrine. Because of the abuse potential of amphetamines, they are not used in the military for treatment of side effects, but the last I heard the military does use ephedrine. Typically they use 25mg of Phenergan and 25 of Ephedrine for embarked Marines on a routine basis.


On Revelation, we've tried Stugeron, but did not find it effective, either personally, or for passengers.


NASA, many years ago, made their own "Scope/Dex". It was a large gel capsule with scopolamine and dexedrine tablets inside.  It worked, but not as well as promethazine (PHENERGAN), so Scope/Dex was discontinued.


Studies were done by NASA with Scopolamine patches.  There was a 10-fold variation in Scopolomine blood levels. with the patch. There are multiple determinants for its absorption.  I still remember one of the volunteers, an engineer in our project, who went from being a quiet, shy person to a "drunken, 'life of the party".  She had to be taken home from work...  Trying the patch, on-shore, would be advisable for anyone contemplating its use at sea, although absorption could still be dramatically different "at sea".


We used Phenergan on Day 1 of our flight.  It was highly effective, and in that setting, didn't seem to cause sedation.  Giving it early, before the person is on the verge of vomiting, works best.  At sea, I take it at the first sign of nausea, as it's better to prevent than "treat".  In space, alertness did not seem to be a problem.  I've taken it as a crewmember, doing studies on the NASA KC-135 (aka "The Vomit Comet").  It does make people sleepy, but they can function better than if they were nauseated and vomiting.


There's no question that being in the cockpit, fresh air, focusing on the horizon,  or even letting the person steer the boat all help.  "Steering" helps even if the boat is actually being steered by the autopilot.

Motion-sickness is thought to be caused by a mismatch between the vestibular and ocular system signals, so moving as though steering the boat reduces the mismatch.  


If someone's nausea has proceeded to vomiting, use a suppository.   When a vomiting person takes Phenergan and then vomits again, there's no way to tell how much of the drug was absorbed.  Too much can be toxic.

As I reported earlier, our Group member, SM owner, Circumnavigator in a SM and International Space Station, Astronaut, and Professor of Cardiology, responded with the following advice:

Regarding motion-sickness treatments, I checked with my NASA colleagues, who wrote:
Phenergan (promethazine) is still the treatment of choice for Space Motion Sickness/SAS. As you know I first used it to treat a crewmate on an earlier STS flight and it became the treatment. Questions were raised if ondansetron (ZOFRAN) would be better.  Ondansetron was trialed on ISS (the Space Station); it was not as effective as Phenergan. NASA Flight Medicine thinks that Phenergan will remain the treatment for the foreseeable future because it is effective and that the actual side-effects experienced as opposed to what appears in the package insert have not been an issue.

As you are probably aware, Phenergan can be sedating, but the sedative effect can be countered by amphetamines or ephedrine. Because of the abuse potential of amphetamines, they are not used in the military for treatment of side effects, but the last I heard the military does use ephedrine. Typically they use 25mg of Phenergan and 25 of Ephedrine for embarked Marines on a routine basis.


On Revelation, we've tried Stugeron, but did not find it effective, either personally, or for passengers.


NASA, many years ago, made their own "Scope/Dex". It was a large gel capsule with scopolamine and dexedrine tablets inside.  It worked, but not as well as promethazine (PHENERGAN), so Scope/Dex was discontinued.


Studies were done by NASA with Scopolamine patches.  There was a 10-fold variation in Scopolomine blood levels. with the patch. There are multiple determinants for its absorption.  I still remember one of the volunteers, an engineer in our project, who went from being a quiet, shy person to a "drunken, 'life of the party".  She had to be taken home from work...  Trying the patch, on-shore, would be advisable for anyone contemplating its use at sea, although absorption could still be dramatically different "at sea".


We used Phenergan on Day 1 of our flight.  It was highly effective, and in that setting, didn't seem to cause sedation.  Giving it early, before the person is on the verge of vomiting, works best.  At sea, I take it at the first sign of nausea, as it's better to prevent than "treat".  In space, alertness did not seem to be a problem.  I've taken it as a crewmember, doing studies on the NASA KC-135 (aka "The Vomit Comet").  It does make people sleepy, but they can function better than if they were nauseated and vomiting.


There's no question that being in the cockpit, fresh air, focusing on the horizon,  or even letting the person steer the boat all help.  "Steering" helps even if the boat is actually being steered by the autopilot.

Motion-sickness is thought to be caused by a mismatch between the vestibular and ocular system signals, so moving as though steering the boat reduces the mismatch.  


If someone's nausea has proceeded to vomiting, use a suppository.   When a vomiting person takes Phenergan and then vomits again, there's no way to tell how much of the drug was absorbed.  Too much can be toxic.

Scott,

Use "Vinaigre Blanc" bottles you buy at Carrefour, just $2 a bottle. Use it for vinyl, inside lockers. Cheap and does the job.

Our original AMEL hatch holder is at the bottom of Annapolis harbor. So we created a new one. 24” x 7/8” SS tubing, 2 elbows, 2 end caps. 3 settings. Mesdames et Messieurs, voila...

Re: Lifting the dodger on a Sharki

I did like Gerhardt's solution.  I did mine prior to his.

 Areas,
I elected to lift the dodger since I was not confident in my ability to do a good woodworking job in Greece. My other two choices were to cut the hatch in half or cut the trim and rebuild it.
The front of the dodger refused to cooperate. It is somehow locked in place. I wonder if someone put an extra screw up into it and then covered it with the headlining. Graham Johnston’s on Zephyr has lifted his twice, with no problem. Not me.
Bill Rouse posted the photo of how a prior owner of Gerhard Mueller’s Sharki had cut the trim. Gerhard shared that with me when he got to his boat in May. 
I could not see a way to cut and veneer the hatch without the wiper causing problems with the veneer.
Bill pushed me over the edge by suggesting the Gerhard solution. I had found some teak molding from a prior boat on board that would work, look OK and cover up my butchery with an oscillating saw.
The hatch is out and ready for veneering tomorrow.
I wanted to recount my experience to illustrate the multi faceted support of the forum. My solution was an amalgamation of several prior experiences by forum members, modified by my situation. I’m really looking forward to not having an eyesore masquerading as a hatch.
Thanks to everyone.

Greg,
I had to re-make mine. Rather than take off Hard Dodger we cut ours so that it would slide out.  We used wood bungs to join them back togetherwith new wood of course.

Hey all,
I need to resurface my hatch but, as we all know, that requires lifting the dodger.
I have taken out all the obvious bolts and the dodger is releasing except that it seems anchored firmly at the pointy end of the pare brise.
There is a ferrule (guiding the traveler adjustment) at the “pointy end” with two screws. They are out. No evidence of fasteners under the headlining at the “pointy end.”
Seems to me you should be able to take out the bolts and it should lift off, but it isn’t. It is rock solid at the front end. I must be missing something. Henri magic?
 Has anyone else experienced this problem with a Sharki dodger, or am I the first?
