    Following on from our brief conversation in the yard, if you look at either Annie's blog or Shirley's website (speedwell of Hong Kong) you'll find all the information you need about building a tabernacle.  

    Best of luck with the project. I'm around for a few more days before heading to Cornwall.

    Hi Brad,

    Sailboatdata gives the Nomad's sail area as 187 ft2 / 17.37 m2, which gives rather a low SA/D ratio.

    Interestingly, it also gives the Westerly 22 sail area as 227 ft2 / 21.09 m2, which would be better.

    My Hunter Duette 23 carries  a sail of 22 m2 (on a boat with less displacement than the Nomad), on a keel-stepped mast that is 9.35m long. This is a high AR sail, so at a guess, a lower AR sail of 21 m2 is going to need a keel-stepped mast of at least 7.5 - 8 m.

    You won't find an alloy tube of this length. If your budget doesn't stretch to getting a conically tapered alloy tube from the Aluminium Lighting Company, then the next best is what we call a hybrid mast - making a tapered topmast of wood to go into as long an alloy tube as you can find, usually 5m.

    Hi Brad

    Welcome to the JRA - if you explore the website, you will find we are rather more than just a forum.

    Member Tom Davis, in North Carolina is planning to junk rig a Westerly Nomad, so it might be worth contacting him.  I had a Westcoaster (the wooden precursor to the Westerly 22, which came before the Nomad!) many years ago, and converted her to junk rig.  I seem to remember we put 200 sq ft/18.6 sq m of sail on her.  As the designed SA is supposedly 187 sq ft/16.4 sq m, that sounds about right.

    I wouldn't use a straight aluminium tube, myself: it would look so ugly, apart from anything else.  I see you are in the UK and if you look  under Junk Information, you will find some links to manufacturers of flagpoles and/or lamp posts that may offer something that wold suit you for a mast.  (If any of the links don't work, please advise the webmaster.)

    We put our mast in a tabernacle, and it was about 6m/20ft above deck - I think you may need something longer, if you are going to keel step it.
