Do you think this mast would be suitable for my junk rig?

    I too am looking for a mast at a resonable cost and came across this English site who sell Valmont lighting columns. http://www.stainton-metal.co.uk
    I will try them tomorrow, see if they will sell one to me and get it transported to Preston... Can but try.

    Good on ya, mate :-)

    Two more links for you, MD!


    Got it, D. Fixed the broken links, and added all the distributors for Bebi while I was at it... New Caledonia, Aus, and NZ for the Far East gang. http://www.junkrigassociation.org/commercial_links

    One and All: I'd like to build links to Charting Software since the Software Dept. is very thin, but I really, really don't know where to start or what's good and what's junk, oops, I mean rubbish. Please help here with recommendations. (I presume charting software is normal now. I prefer paper charts but, you know, "getting in tune with the times" and all that.)

    Thanks,

    I use the OpenCPN software, Open Source and free. It can be found at:

     http://Opencpn.org. 

    Now for the qualifier, I only use this software for planning purposes as I don't have a computer up and running on Easy Go while on passage. I anticipate using the software to find the way into harbours that I don't have charts for. 

    Possibly a more techy person could look at this software for connecting to GPS and all the other features it purports to have?

    Good work, Graham, the project is coming together.
    The company's name is Valmont/Sermeto. I had a quick look, the model appears to be "Venus", a lamp pole available in 165, 180 and 200 diameters, and from 7 to 15 metres.

    My masts are from spun-tapered poles made by:
    and the model is a lighting column called "Boulevard".

    Here's a link to fiberglass poles...
    Shakespeare Composite Structures - Round Tapered Poles Read the PDF to see if they have something you could use. I have no idea if any would suit or how much they cost, but I'm sure they deliver to the UK. (The link could be helpful to others.)

    Annie, your mast is big enough and looks great with its painted topmast. Junk rig building is "the art of the possible", and working within such constraints as we find ourselves under, and within the limits of the materials and facilities at our disposal, we can achieve a good sea-going rig, whereas it would be quite impossible with other rigs.
    I guess that Freyja's displacement has to be 4 tons or so, laden for long distance voyaging, (it's quoted as either 2.85 or 3.3 tons) which is why I think she needs a size larger mast. The working sail area is given as 308 sq ft, (http://www.eoa.org.uk/forms/E29Overview.pdf )
    but this is rather low. I would want about 400 sq ft, rather more than on Fantail.

    Fantail displaces 2.5 tons, by the way.

    I should write all this up for the JRA, but first wanted to be sure that the mast didn't fall down.

    I have a zillion photos which I am postponing putting in the Box for the same reason, but can send you a selection so that you get an idea of what's involved.

    I am a very inadequate woodworker, but epoxy is the bodger's best friend and in spite of The Great One's comment, I think the whole thing looks quite professional.

    David has pretty much answered you. I suspect the section you are being offered was designed for a stayed rig and is not really suitable for a free standing rig. I certainly think that a 4mm wall (with that section) is likely to be to light for your boat.
    Thanks Paul, I have now emailed Nedal and asked for a quote. I will also read up on how to fit a wooden top mast to an alloy tube.
