Electric Winches

Posted 01/12/16 by Andy Roy:
Has anyone fitted electric winches to a Mk1? Ageing (me) and falling crew numbers are rendering our 46 unuseable for two.  Does anyone have experience of electric winches and do they make things easier?  No point spending £10k if it don’t make much difference.

LED Salon lights for Katface (Swan 46 Mk I #62)

LED Salon lights for Katface (Swan 46 Mk I #62)
Katface has a lot of older Hella ceiling lights. All of the ones I have looked at have cracking in the plastic base and have showed signs of shorting and heating at the power wire connection. These are corroded and feel like solid wire. Conjecture is that minor shorting has caused …

Rod Rigging

Posted 24/1/16 by Lars Ström:
It is suggested you contact Navtec for the rigging, they have good records of what they delivered to this yacht. It is likely that some of the fittings are not in production any more, this means some lead time is needed.

Corroded Mast Step

Posted 24/1/16 by Lars Ström:
It is likely that there is severe corrosion on the mast step if you decided to replace it. Otherwise it might have been of interest to determine the remaining steel thicknesses in the critical areas.
You mention stainless steel for the replacement, assume AISI 316L is in question. It should be noted that this material has much lower strength than the original …

Dissipating the hydrogen gas that is generated by charging lead acid batteries

Posted 3/12/2015 by Paul Basson/Foreign Affair:
I recently invested in a dual gas detector, which monitors LPG and Carbon Monoxide.
I was surprised to find that the Carbon Monoxide alarm would go off when the boat was unattended.
I suspected the battery charging and checked with the manufacturer, who confirmed that the Carbon Monoxide sensor will also detect Hydrogen which is generated during battery charging.
I checked my boat …

Hydraulik Power Pack on Swan 46

Posted 10/09/2015 by Lars Ström:
Dear Sven
I think we can agree that these yachts have lots of installations. At the time of build the available spaces have been evaluated and decisions made where things go, and the convenient areas are probably all occupied. The installations vary from boat to boat depending on the owner’s preferences.
Kind regards, Lars

Autopilot Upgrade

Posted 08/09/2015 by Lars Stöm:
Dear Tom,
The Jefa 300 Nm drive unit should be suitable, has enough power.
Pls take a look at the table denoted “Jefa sprocket drive calculation” on their website. You have very close to 1 3/4 turns on the wheel, and the total rudder angle is 70 degrees. This means a sprocket with 15 teeth is recommended on the wheel shaft, but now …

Autopilot Drive Unit

Posted 03/08/2015 by Lars Ström:
Out of memory the standard autopilot installation had a rotating drive sitting on a cradle under the cockpit floor. If you have a steering system drawing in the ship’s papers it shows the arrangement.
Your description indicates your set up may be slightly different. 
Fracmo is still there, and it is suggested you contact them for possible replacement:  www.fracmo.com

Is it possible to obtain the leather spreader covers like the originals?

Posted 22/06/2015 by Paul Basson/Foreign Affair:
Hi Andrew,
I have replaced my spreader covers several time, by using a local artisan who supplies leather, amounts the mast and sews them on.
Regards, Paul

Lewmar traveller car repair

Posted 15/04/2015 by Tom Venator/Katface:
As you can see on the “broken sheaves” picture he flanges on the sheaves for the traveller line on the Lewmar traveller car failed. A call to the Lewmar representative in the USA found that Lewmar no longer supports this traveller design with spares or documentation. I was invited to buy and install a new traveller system. Through trial and error, good advice, …

Rudder Problems

Posted  20/02/2015 by Lars Ström:
It is suggested that you inspect the upper end of the rudder stock casing closely, as there could also be another reason for the leakage – the lower bearing housing has come loose from the surrounding GRP. In this case the water enters between the steel housing and the GRP laminate around it, and there is a slot visible.
In the photo the …

Refrigeration

Posted 23/02/2015:
I assume that you also have the 220v compressor, otherwise why would you keep the original plates.
Unless you are planning to put in a 24v compressor to drive the old plates, I did not think that was an option.
To be honest, I have only used the 220v compressor once since I had the 2 24v systems installed, but its a reassuring backup.
My old system …

New engine for Swan 46

Posted 15/04/2014: Foreign Affair New Engine
The engine was 18 years old with 4000 hours of use.
It was still running well but we would occasionally have a problem, and each time the problems appeared to get more serious and deeper into the engine.
The last problem was a year ago at the Middle Sea Race when we had to replace the fresh water pump, which required removing …

New Teak Decks

Trumpeter is lying at her berth in Sotogrande and having new teak deck laid on. We have reached the interesting stage – the old teak removed, deck sanded down and all fittings removed. The man who is doing it, single handed, is a veritable artist. He has sawn the teak tree trunk and cut and shaped all the bits of the jigsaw. The thickness is …

Teak Deck Caulking

One of our members experienced the following: For the seam caulking we used Mapei Silwood Decking. As the boat is berthed near a boatyard, we thought we would protect the finished deck by applying a sealant – we were recommended a product known as Teak Wonder. Everything seemed alright for the first two to three months, but we then noticed that the rubber caulking seemed …

Mains power hot water

12/02/2014 Lars: Referring to the heater voltage, the AC on board system can be set up for either 220 or 110 V, and the outlet voltage on board tells which one it is. The heater should use the same voltage as the outlets. Pls check. If there are shore inlets for both 220 and 110 V there is a transformer for one of them so …

Sails

Problem with the custom stainless steel pipe

Posted 12/02/2014:
Possible cause electrolysis.
Lars – Yes, my answer mentions electrolysis as a possible reason, although I  referred to this as “some galvanically very active substances”.
Electrolysis is a rather broad term, and can be divided into electrolytic and galvanic corrosion. 
The electrolytic variant is caused by a leak in the electrical on board system, appears unlikely here because it would require cabling in the area, and occur …

Maintenance log
