Hey Mark,
That would have been Jonathan.
We had a great passage to the Azores.
Yes it is a small world. I am nostalgic just thinking about all the  ocean  passages. Some easy and others not so, but  every one of them left me feeling fulfilled and perhaps thinking that the world is actually quite large, at least from the deck of a small boat.

On the Super Maramu there is a removable panel in the aft head on the upper, inboard side of the forward bulkhead that give us access to the cables coming down the Mizzen mast including the AIS Antenna, Radar, Weather Fax, and Cockpit Light.  I don't know if it is the same on the 54.

I think I met your mate Kevin(?)  a few weeks back at Herrington Harbor North Marina in Deale, Maryland USA.  It's about 20 miles south of Annapolis.  He says he helped you sail Amelia across the Atlantic.  What a small world we live in!

Hi Arno, I realize that with your modification, the point at which you can attach the line to the door is further away from the wall than in my case. where I simply attached it to the cross wood and tt is perhaps for that reason that the balance weight created more friction.  I think that if you extend the point of attachment to the right, the friction will be substantially reduced.  For this you may need to fabricate a plate to extend the point of attachment of the door towards the wall.

Hi Arno,
To avoid the weight from sloshing around I used the track that I mentioned to guide the weight along the vertical direction.  It is very smooth because it runs in roller bearings.  With this, the weight could only slush when the vertical acceleration of the boat is greater than 1G,  which should never happen.  It is true that the pull from one side of the door creates some friction but still much less than the weight of the door.  Also, that friction prevents a rapid fall of the door.  I am not sure that the weight of the 54's door is the same as that of the SM but there is still some room to increase the size of the weight if you need to.  Worth testing before making the counterweight

Thanks Arno,
There never was an AIS system on the boat. I am installing a receiver now. For the moment I am using the main VHF to test it and it all works.
Now I just have to find the cable from the mizzen VHF antenna and we are done…

Hi Jose,

I really like your idea. Very clever. I used to live in a house that had that system for the sliding windows.
For the boat it seems to have some additional challenges.
- How do you prevent the weight from sloshing around when the boat is in motion?
- I tried to support the weight of the hatch on one side but the hatch has the tendency to rotate slightly and prevent a smooth motion upwards as a result. What did you do to prevent that?

Cheers,

Further to my last email


So we have the triatic weather fax antenna.
Then there is a VHF type tall antenna?
And a stubby antenna?
Also what does BLU mean? Is it French for SSB ?
You can see that the starboard mizzen backstay has an isolator top and bottom so that is my SSB antenna.

I am hoping that some group knowledge may help me.

I want confirmation that the antenna on the mizzen that looks like a VHF is actually a VHF antenna (spare)
Secondly I can not find the end of the cable from it to the chart table area. Any ideas?

Re: Motion Sickness

I agree with Trevor the posts on this subject is one of the best attempt to describe and explain one of the most mysterious maladies that affect sailors in general. Thanks to Bill for bringing the subject up and all that followed. I felt Scopolamine made me feel like a caffeine overdose and didn´t go well with me.I have found that Meclizine HCl works well for me and those in my crew that tend to get sick. I can suddenly become sick in calm nearly no wind situations, and survive rougher sea conditions. Still a mystery.

Re: Bow thruster does not work in one direvtion

ngtnewington Newington
 

It seams to me, for those of us with lead acid batteries. It is important to minimise the use of the bowthruster. Having owned other boats not fitted with BT’s and manoeuvred perfectly well this is easily achieved. Using maximum 2 second bursts of the BT should be enough.
If a two second burst is not going to be enough and a difficult situation is developing then I recommend having all chargers on and/or changing plans, because if one needs the BT and it has overheated not only have you damaged your battery bank, you have placed the boat in a potentially dangerous or damaging situation.

Hi Ken, I guess this was to me since you refer to my Super Wind 350. I pretty well agree with all you said though the only thing I might question is the need for life po batteries but that is a matter of choice.

As I said I have not measured the current draw but when I am tight reaching in 30 Knots and I roll in part of my headsail under load there is a big power draw. However all that is irrelevant. I just provided the information as an observation.

The important information is 12 years, 8 years + life out of my lead acid batteries and never running the gen set for the bow thruster. I agree with you that with a motor at idle or near idle the output of any alternator would be minimal.

Of course it is important to note the fact that, except in an emergency being swept sideways where you do not want to go, I limit my BT use to short multiple bursts. If a user puts in into use and leaves in there for long runs the situation is totally different.

I have done the measurements.  My bow thruster takes 480 Amps.  It seems there are some misunderstandings with most Alternator systems installed on the main engines, and the amount of current you will get out of your GenSet.

1. Your GenSet is usually a 6.5KW Onan, or maybe you have a bigger one, but this has nothing to do with the current supplied to the 24V system.  The current supplied to the 24V system is only a factor of the battery charger/s on board.  If you only have a 60A battery charger, you will only get 60A into your 24V battery system while running your 6.5KW Onan.

2. I don't know about you, but when I am backing into a "Parking Spot",  and I engage the bow thruster, the engine is usually at idle. "Most" alternators, on an engine at idle, don't produce much current.  If you have a 100Amp Alternator, you may get 25Amps at idle, but probably more like 15Amps at Idle.  There might be alternators that provides max current at lower RPM's, but would you want this?  

3.  Rated power output of the Super Wind 350 generator is 350Watts, which is about 12 to 13Amps into a 24V battery system.  

4.  I believe the rated power for the main outhaul and furling motors is less than 1500W.  This is less than a 60A load.  There is no comparison to the amount of current the bow thruster consumes.

So, if you have Lead Acid Batteries, and lets say your capacity is 300AmpHours...  If you use the bow thruster with no alternator, and no battery chargers, it will be over 1C, which is not so good for the batteries.  If you turn on your Genset, and your 100A charger, you are still over 1C.  And if you also have an alternator that is adding 50Amps, you are still over 1C.  

Good reason to get LiFePO4.  These issues go away.

Re: Storage Hatch gaskets

Bill ,Just want to double check the size of the gasket. I had a look at mine and they are 1" wide ,but where they are not depressed ,at the edges they appear to only be about 1/2" in height and in the center that bears the weight they are depressed down to about  a 1/4" ,maybe 3/8' . I just wanted to make sure that they might not have been 1/2 or 3/4" in height originally .

Re: Motion Sickness

Trevor Lusty
 

I have studied every line posted on this subject intently. Thank you to every one who has contributed and as ever, sincere thanks to Bill and Eric for introducing such in depth and informed contributors. I have been a member of the group since 2008/9 and consider this thread the most impressive and in depth review that I have seen.
I sailed my boat Seafever of Cuan SM 425 from La Rochelle to Argentina 2007/08. The only thing that made this possible for me was Scopaderm patches. Unfortunately,  by the time I had reached Brazil, due to overuse, I  had developed contact dermatitis as a reaction to the oil that transmits the drug from the patches.
I was considering giving it all up. The boat was my home and my identity, but without Scopderm, I was beaten physically and mentally with sea sickness.
The definition of seasickness for me without patches was,  incapacity to eat, drink,walk, and  all loss of normal body function, leading to dehydration which at some point was going to lead to a very serious navigation or seamanship error.
In Southern Brazil, I had the good fortune to meet Dr Omar Sanchez, a keen diver and sailor  from Argentina, who kindly accompanied me from Uruguay to Buenos Aires and subsequently far beyond.
Dr Sanchez initially saw me at my worst, (not pretty) and after our trip together reflected on my Mal de mer.
He told me that I  was as an extreme case as he had ever seen. Interestingly, this also was previously mentioned when sailing in France by Michel Charpentier!  When I invited Dr Sanchez to accompany me from Buenos Aires back to the Caribbean he agreed on the following condition.
No alcohol, no pepper, very plain food, no over standing you watch, YOU MUST HAVE SLEEP. You will sleep on the floor ( the passageway between the salon and aft cabin). Drink 7 UP, eat apples, and or, any form of ginger between meals, keep drinking fluids. No reading. No prolonged periods at the chart table. All meals cooked and prepared before departure. Use the generator and microwave to heat the meals, serve them in bowls and eat in the cockpit. Bathroom needs facilitated with a bucket in the cockpit. YOU WILL KEEP WARM.
He prescribed the following ,one Stugeron (cinnariazine) and one Kwells (hyoscine) taken the night before departure, repeat at breakfast. Then one pill of each, taken alternatively every four hours, until the end of the trip.
We experienced some challenging ocean sailing together.
The effects of the medication are, dry mouth and sometimes a taste as if you have a bad cold. The sleepiness effect is negated by the nervousness and adrenaline  we all experience before setting out to sea.
Thirteen years, and tens of thousands of ocean miles later, I have felt badly off colour twice - I had forgotten to take my pill or pills.
I have NEVER been sick since and always been in full control of myself and my vessel and therefore less fearful.
Thanks to Doctor Sanchez and the sagacious elder members of this site for their advice and support on endless subjects, I have continued to sail with more general knowledge  and  a reduced level of fear, but never without the medication.
For the naysayers, please do not criticise  this remedy and warn of possible life debilitating diseases. I am sixty seven, I have been blessed and allowed to experience people, places and experiences previously undreamed off. All I can offer is, that this solution works for me and if it helps someone else, then in some small way, it will  repay my gratitude to  others who have helped me live and sail far beyond my dreams. For me, it has all be worth it, I understand how others  have different values, concerns, and responsibilities and just like the ocean I totally respect that.
 Chantier Amel respect de la mer.

Fair winds  and well rounded  seas to all.
