Hi I have a Sun Odyssey 49 (2004) with Sparcraft mast and furling mainsail. In the mast I have mounted a Raymarine radar just above the first spreaders, but I cant seem to get the cable out at the bottom. The cable goes into the mast a fabric made hole just beneath the radar. I have managed to get a string all the way through to the bottom, but it seems as if the radar-cable is prevented by something a short meter from the bottom. Does anyone have any experience with this? I'm hoping not to drill multiple holes to get the cable out, but right now it is stuck... Thanks in advance  |

Presuming it is not how you have joined the string to the cable (IE taped so the profile is as smooth as possible on the join) Does the string go through smoothly? perhaps swap up to a 10mm or so line of similar size to the radar cable first - if that goes through OK then you should get the cable to follow

Hi The string runs fairly smooth through. I will try to use a rope first, that's a good idea, thanks Is it common to that these cables are difficult? |

This is a timely topic for me because I am about to install a Simrad 4G radar on the mast of our year 2000 SO40. We have never had the mast down, so I don't know what it looks like inside. I have read all of the 'radar on mast' posts, and I have concluded that it is doable... but I still have a few questions:
1. Is there a conduit inside the mast? (More than one?)
2. If so, where is it situated, and how does one align a mast penetration, both at the 1st spreader and at the mast base, such that it enters the conduit?
3. Presently there are four cables entering the base of the mast: a fat VHF coax; a three conductor steaming light / deck light cable; a two conductor cable for the masthead anchor light; and a wire for the masthead wind instrument. Do all these cables run in the same conduit? If so, would there be room for the radar cable?
4. How does one avoid penetrating the conduit when attaching the radar mount to the mast?
This should be fun!

I , or other members for that matter , can give you an explanation in words , but that will not visualize the setup for you of course.
If I get to my boat today , which I probably will like every other day ;D , I'll take some pics from the inside of the mast and try to go as far as I can reach with the camera.
The pics will answer all 4 questions in an instance.
Regards

Sailbleu,
Thanks... I eagerly await the information, words, and/or pictures.
BYW I am a new user of this fourm, and I will probably need some advice on retrieving posted pictures.

Sailbleu, Thanks... I eagerly await the information, words, and/or pictures. BYW I am a new user of this fourm, and I will probably need some advice on retrieving posted pictures. k17 Hi Kenneth, this pic should help you on the way. [a href="  "] [/a] Please note my radar cable - which is removed because my mast is off and up to now I did not splice that cable yet (see other topic) - was not running through one of the channels (conduits) but was floating free in the remaining open space. As you can see the furler/foil is seperated from the cables section so besides making some rattling noise inside the mast the radarcable can not be compromised by anything. Also fixing the radar mount will not effect the conduits , as you can see the front of the mast is on the right. Regards |

Thank you!
We eventually got the cable through. It was just a matter of taking it in and out a few times. It seems as if it stopped on something 80cm of the bottom. We also tried getting it through the conduits, but that was even harder.
PS: Underneath the mast there is a connection point for DC-power. One of the cables is marked "opt" and goes through to the electric board, ready to be connected in the aux-slot. Genius! But I can't seem to find an original switch/fuse that fits in the board. Does anyone know who supply these?

Sailbleu,
The photo is very informative, yet I still have some questions.
I have a classic mast, with the mainsail hoisted on a groove at the back of the mast, not in-mast furling.
1. Do you (or anyone else) know if the classic, non-roller furling mast has the same conduits as the in-mast furling type shown in your photo?
2. How far above the deck is the bottom of the conduits (I presume that the photo is taken at the bottom of the mast)?
3. How can I determine where the top opening of each of the conduits is?
4. Which conduit, port or starboard, carries the steaming light cable?
5. The steaming light is about four feet above the first spreader. I want to mount my radar right at or slightly above the first spreader. well below the steaming light location.
6. Is it reasonable to consider drilling a hole slightly off center in the front of the mast in expectation of intersecting and penetrating the conduit in which the steaming light cable runs? Could I then use that penetration to run the radar cable down to the base of the mast inside the steaming light cable conduit?
Thanks for any help with this!

Hoppy, I'm quite sure it is a Z spar, classic profile, but I have to go to the boat to get the model number to determine the correct profile. Can anyone address any of the several questions I posted on Nov. 6th?? Thanks, k17 |

I had to replace my wind vane cable on my SO45.2 ... it took a whole afternoon to get it through with me up the mast and friends helping at the bottom. What saved the day was ... dish soap ... pouring generous amounts down the piping was the trick.

Alexandria,
I'll bet you had bubbles at deck level for months ! ;D
Since you were working from the top of the mast, your situation was somewhat different. My issue is that I am trying to intercept one of the conduits from spreader level.
I would have to drill a hole in the mast as well as into the conduit. The trick is determining where on the face of the mast that hole would have to be.
Any ideas?
