Hi
My hanse 342 is now 11 years old (2007) so it seems the time to change the little wires that secure the mast, shrouds and stays. Could a knowledgeable sailor tell me: 1) is this the right time to change? The yacht is 11 years old and it has done over 17000nm most of them undef sailing but without stress 2) a rigger asked me for the "mast plans". I looked on my hanse 342 dossier and I coukd not find this. Where can I fjnd this? It needs to be very accurate accordingly to the rigger... Thanks |

Normally there should not be any wear on these. Many 40 year old boats have not changed any wires.

I changed mine at 8 years and i have had 4 new forstays in 13 years, partly because i have been experimenting with mast rake) and also due to furler damage . but for length surely your rigger will use the old shrouds as a guide when the mast is lowered to renew them. He will tape the rigging screws so he knows how much they were tensioned & make the new ones slightly shorter to allow for stretch

On my 2003 341, we changed the fore-stay last winter as it showed some wear near the top, but otherwise the rigger said everything else was was ok. My boat has not done as many miles as yours.
My insurance contact says that most companies have given up on the "10 year rule", but check with yours. He did recommend that you were able to show proof of having the rigging inspected every now and then. Picking up on Samuel's advice, really the key measurement you want to do before you take the mast down, is check the mast rake, making sure you know how the boat is loaded fore and aft, so you can repeat the check later. |

There are
many different views on this and you can have these electrically tested with
special kit that indicates how worn they are, especially the joins by way of
the resistance. However, this is not cheap and can cost around a third of the
price of new rigging wires. I took the view last year to replace mine at 14
years old. The general consensus is this likely needs changing at 12 years old
dependent on the amount of sailing that has been done and under what
conditions. Your insurance company is likely to have a view on this so worth
asking them. Although the old ones don’t appear much different apparently the
joins can just fail when old and bring the rig down. My rigger took measurements
of all the wire rigging, forestay, backstay and the six shrouds and made up new
for all of these. He then fitted them when I had the mast down and when this
was replaced they all fitted perfectly.
The cost for Blue Horizon was £900 in 2017. The shiny new bottle screws look good and I am now happy the rig is good for another 12 years. |

Hi Robh,
Can you post the measurements of your rigging if you have them? |

I replaced mine after 20 years. The original rigging was still in good condition.
Initially
I pulled a tape measure (the metal kind), up the mast, with the main
halyard to measure the length. As this could have been +/- 20mm. I sent
the Mrs up the mast with the tape measure to confirm length and it was
within 10mm. After getting them made up they were too short
and I had to drop the mast and get them all made up again. I don't know
where the miss-calculation came from. I would recomend doing
it in stages. Start by removing one of the inner stays and get two made
up to match. Insure you stay the mast with a halyard for the time being. Then replace the
outer stays the same way. My personal opinion is: Replace the forestay, as these take a lot of punisment but wait another 5 years before replacing the rest.

Would it not be better to start with the longest ones first so if there is a mistake one can cut the wire shorter & only put a new fitting on one end rather than throw the whole thing away??? Agree about the fore-stay renewing the forestay early though
