Oceanranger forestay and backstaydimensions

Post by JohnBrand »

My local rigger has surveyed the standing rigging on my Oceanranger Sula. There is a problem with the lowers, which are very slightly misaligned at the mast fittings. There is nothing specifically wrong with the rest of the standing rigging, but the rigger advises that as it's 10 years old it is theoretically at the end of its safe working life. Sula has been extensively cruised, including a couple of Atlantic crossings, so I suppose the rigging may have been worked harder than some. I might as well have the peace of mind of changing the rigging now.

One company quoting for the new rigging says that the original forestay and backstay were 8mm, but the advice now is to go for 10mm. This makes a very considerable difference to the price - £435 for the forestay instead of £268. They also point out that 'the Furlex 300 range of furlers needs a special selden forestay with the top bearing fitted' - which if I change to 10mm will be a further £342.

Has anyone else come across this advice?

If 8mm has survived 10 years and a double Atlantic crossing, then surely it must be strong enough. My advice would be to contact Ed Dubois design studio to see whether they consider a change to 10mm is adviseable.

If you are going to change the rigging yourself, then try https://www.s3i.co.uk/ for a quote (make sure it is marine grade s/s). I used them for new guard rails and it was all very simple.

Agree previous posting. I have an Oceanranger and have done several Atlantics, Azores etc and many other bluewater trips in her. I've also rebuilt the rig twice.
I have stuck with the original rigging size, although my rig has a few other bits too...like spectra/dyneema running backstays from under the upper spreaders to the quarters, and a second removable forestay just inside the original.
Your after lowers should be thicker than the other long wires, and the intermediates thinner.
The aft lowers are worked very hard on these rigs and so are their chainplates. The chainplate U-bolts should be inspected very closely every 10 or 12 years, and ideally replaced, at the very list at mid-life. They work at the neck where they enter the deck. Replacements should have a wide baseplate and the U-bolt bar should be angled in to match the line of the shrouds exactly in order to lessen leverage effort on the U-bolts. I fitted new ones before my last double Atlantic. They need to be made specifically. The drawings are with a local company in Fareham, but Trafalgar Yachts can get them.
Ideally your babystay fitting should have a strong back-up below. It is quite common to fit a tie bar, tube, or internal shroud down the forecabin bulkhead to a saddle on the underfloor internal keel moulding. Some owners have gone for twin forward lowers instead, taken to plates fitted either side of the coachroof. I've used an internal wire shroud and bottlescrew.
XW rigging at Haslar Marina Gosport are the specialists for Westerly rigs and have all the dimensions and advice you need for the Corsair, Oceanranger, Sealord, Oceanlord etc.

Thanks for the advice, gents. I agree that the boat's history suggests that the original rigging sizes and setup were adequate, and I am going with them. The chainplates/baseplates were changed 10 years ago to angled U-bolts.

I was amazed by the range of prices quoted for making up the wires. In the end I decided to go with the local rigger at Port Edgar, to avoid having to pallet up and send the old rigging to a company down south. He's using materials provided by Allspars, who are well-regarded and gave a good quote.

The rigger is familiar with the Selden 'top bearing' and is confident that the previous one is reusable.
