Spinnaker block replacement

I try to keep my boast original, and after 22 years, I dropped one of the special Spi Blocks over the side (always tie it on before fixing it to the toe rail)

N

Now these are specially made for Nautor by WiBo Finland. I wasted a lot of time trying to get support from Nautor, emailing multiple times and never even got a response. I contacted …

Holding Tank odour source

After many years of trying to stop the bad odour from my aft holding tank, I discovered that Nautor connect the holding tank breather to the grey water tank breather and pass the combination through a hole on the hull at deck level.

The problem with this is that the holding tank odour, can seep through to the grey water tank and permeate the cabin. Or …

Jockey pole fitting

Hank Graziano (Pandora #034) -I sheared the toggle off (pic of the entire assembly attached) – mast fitting and pin ok.  I contacted Nautor parts – they offered to make the part but it was summer vacation so there would have been a delay.  I ended up reverse engineering the part and having it CNC machined –  it did the trick under the time constraints.
Hank …

Swier Hull 58 – Running backstays

Running backstays
The running backstays have been replaced with dyneema grade. As the previous owner never used them and the sail plan does not show the required blocks and line arrangement for this function could you be so kind and check how these where originally intended to be used and tensioned.”

Swier Hull 58 – Stoppers and jammers

Stoppers/ Jammers
In order to operate the different control lines in good manor I want to add LEWMAR jammers for the reefing lines and the staysail halyard aheads of the port rearmost winch on the cabin. According to the deck laminat drawing RITN NR 021-0109 M has the reinforcement type 4x450M +2x500WR. Is this sufficient to attach the jammers for these two control lines to ?
Also …

Setri baby – stay release

Paul – I fitted this after I took delivery of the boat. However a manual quick release also would work for jibing the pole which can be dipped behind the forestay.
Lars – You can choose to have the pole downhaul double or single ended. The set up was originally planned to enable double pole jibes, may be a rare manoeuver these days.
On the subject of …

Setri – Asymetric tack

A bowsprit would improve performance, and some boats put a spi pole on deck to act as a short sprit.
I just use a tack line from the foot of the forestay.
Lars – Is there a turnbuckle with handles inside the babystay shroud roller? if not, you can either have one made (I can send drawing) or you take a look at Wichard tensioners.
If I guessed …

Setri – Spi Set Up

Paul – I have all the original drawing for my boat, which includes “to scale” drawings of the deck with spi poles.
Lars – There should be deck fittings abt 1 ft aft of the stemhead for screw-in spinnaker pole downhaul (fore guy) blocks. From there the lines are led aft to convenient winches.
Do you have a drawing that you could share of the spinnaker pole …

Setri – Anchor stowage

Lars – The shackle is used for locking the aft end of the anchor shank to a deck fitting. Is the deck fitting for the anchor shank still there? A small plate with a bail?
We are making progress on upgrading Setri. Can you identify the parts in the attached picture and let me know where and what they are used for?

Bandit – VariProp performance

Noticed the information you provided, and would appreciate very much to get more information. A few more rpm/speed readings including the maximum would be of interest, as well as the propeller size and number of blades. Kind regards, Lars

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)

Posted 20/06/16 by Tom J. Venator/Katface:
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
