    Rigging questions

    in TechTalk

    Posted

    All good, then the hardest thing you have to do is find the right rigger- oh, and pay the bill! Where are is the boat?

     

    Whangarei.        But,  I would still like ideas and suggestions....based on my questions so I can talk to the rigger and at least pretend to make informed decisions?  Especially on the cutter rig idea and running rigging?   Or just tell me I am over thinking it all and why?

    Ok, firstly, if you are going to get cat 1, you’ll need both the receipts for rigging work, and to do the work properly. The advice above of getting a good rigger is not bad. However, if you’re going to do this yourself, it sounds like a bit f a learning curve is ahead.

    Spreaders don’t last forever, and the bases at the mast bear significant compression loads. If they are badly corroded, or you are in any doubt, then you MUST see a professional rigger. If required, they can make you new ones. Spreaders are way cheaper than a new rig,

    Consider all the primary structures of the boat, keel, hull, keel bolts, hull deck join etc, and whatever you work on, take pics for the cat 1 inspector,

    So presuming all that is good, the rig. Stainless 1x19 wire is the easiest and best. You can take the old stays off and take them to a rigger, and have him make up new ones. Swage fittings are cheapest, so getting a rigger to make them up is likely to be similar to making them yourself with swageless fittings. However, if you make them yourself, you can make new ones anywhere with just a spare cone and wire. Swageless is, IMO , a great idea on a cruiser. There are several options, Norseman, Sta-lok, searig and others. Check the pricing,

    When you put the rig back together, it needs to be set up and tensioned correctly. I suggest you by Ivor Dedekam’s book sail and rig tuning, and follow the instructions in there....

     

    I will not be doing this myself...I should have put this in my initial post....sorry.

    I have a few questions about rigging. 

     

    I am replacing the standing and running rigging on a Nebe Miura 31

     

    http://sailboatdata.com/viewrecord.asp?class_id=7591

     

    Masthead sloop. 

    The boom/mainsail foot, is about a foot longer than the designer specified.

    Furling 140% genoa [on its very last legs]

    There is a single forestay, twin backstays, on a single spreader mast, with common garden variety setup of cap shrouds and two lowers per side. 

     

    With the standing rigging.  I am currently thinking of replacing stainless wire rigging with the same.  What are the local options? What is the best type of wire rope and why? 

    With regard to fittings, what are the key differences between swage fittings or norseman/sta-lok ends? 

    As I need to replace rigging and the genoa, should I consider this an opportunity to install an inner forestay and converting to a cutter rig? or am I over thinking?

    Do spreaders have a defined lifespan? Mine look heavily oxidised from deck level [Aluminium].

    What do I need to know about the turnbuckles?

     

    What else do I need to consider?

     

    The running rigging is very tired also.

     

    I do not need super high performance anything. I like simple, yet elegant solutions.  I would like longevity, chafe resistant, neglect resistant, naive resistant, running rigging. In that order of importance.  I don't mind paying a few dollars more per metre, for a better product.  My Grandfather was one of the biggest tight arses in this universe. He had a very good saying.  When you buy quality, you only cringe once. But there is always a point of diminishing returns. 

     

    So,  what specific products should I be looking at?   I don't need a reason why in this case...Just the majority to agree. 

     

    Should I take this opportunity to add some running rigging or change the way it is currently laid out?  

     

    Currently, there is a fixed forestay. two rope spliced to wire halyards [one for the main, one spare], topping lift is spliced rope to wire, furler + one line either side, one cockpit mainsail reef [that doesn't really work. But that could be the operator], outhaul and vang.

     

    I have two poles.  I am not sure what type they are or how to use them. I think they are both spinnaker poles. I have no other sails, other than the almost new main and almost dead genoa. 

     

    In a couple of years time, I plan to do a lap of this country and then spend a few years sailing the tropics.  

     

    I am very open to my assumptions and ideas to be criticised.

    Well that is at least far better than the Fuel thief that was siphoning fuel from cars in a street one night. Came to a camper van and there was the Fuel container and hose dangling out of the pipe on the Camper and a pool of vomit on the road. He had dropped the hose down the Blackwater holding tank and sucked. :roll:  :razz:

     

    Haha!!    That is gold!

    Hmmmm mcp thats a bloody good idea - only trouble is i can see a new thread starting in a few weeks time "generator left running in dinghy all night"        In actual fact its easy to find an anchorage with no houses or other boaties for miles in the Pelorus  

     

    You will be fine mate.   A small generator in a dinghy.   Worst case is it will catch on fire and the dinghy will sink and put the fire out.  

     

    Honestly,  that is what I would actually do in your circumstance.  It ticks all the boxes and allows for the future.

    Note, I'm not entirely sure I have converted amp hrs properly from 12 to 24 v.

     

    If you convert to watts it is easy.    Voltage x amps = watts.    Divide watts by voltage you will apply, to get the correct amps for this new voltage.

    Vanuatu registration

    With great difficulty. Finally got langkawi to accept a letter from Vanuatu marine division stating they would not provide de registry certificate.

     

    Do you know if they will accept registration of a vessel that is not registered anywhere?  Like a lot of NZ boats.
