Mast & Rigging CAD Database ~ PDF Document

The Vagabond 42 was designed by George Stadel III. It was a follow on design of the Vagabong 47 designed by William Gardner. Both yacht designs were being built by Blue Water Yacht Builders of Taiwan in the early 80's, yet both are sufficiently different that it is wise not to read across from a V47 and assume that the same will apply for a V42.

The most important external changes was new masts with in-mast furling from SparCraft in Charlotte, NC installed by Mack Sails of Stuart FL. The first PDF in the list is the CAD elevation drawing showing the size, position and rigging that was installed. The mast heights are the same as origonal, as are the spar positions and angles. The drawing is copyright of SparCraft so future use for fabrications requires assent of SparCraft. If you own rigger measures your boat then you are not bound by SparCraft.

SparCraft Catalogue and actual Mast/Boom Drawings ~ PDF Documents

This SparCraft 2015 Catalog is over 100 pages and one of the most informative PDF we have ever read when comes to understanding all the things that can go together to make up a new mast using current technology. As SparCraft is a French Company the PDF is in French and English. It is particularly beneficial to learn the termnology and names of all the things that go into a mast, this allows you to have a sensible conversation with the Sail or Rigging company .

The second and third PDF's are reference documents for ourselves which are the detail drawings of the mast and booms that are fitted to Rua Fiola. When the refit was done the booms were delivered with extra length, and it was the responsibility of the rigger to cut and fit for best use. The actual figures for Rua Fiola are Main Boom Length = 185" and the Mizzen boom = 104". This is important as the sail foot PY and EY dimension have to match for the in-mast furling to operate correctly

ProFurl Furler for Jib and Code Zero Headsail ~ PDF Documents

As purchased Rua Fiola had a Profurl furler for the Jib/Genoa. As the refit was to change to a self-tacking Jib which would see a lot of work, the decision was to upgrade to a new NC42 furler from Profurl, while the original NC 42 was cleaned and greased to be used as the Code Zero Headsail furler.

The decision to move to a self-tacking Jib design was a result of seeing a Hanse 375 equipped with self-tacking on Sydney Harbor in Australia bring sailed by a 9 year old with no other person above deck. It was a testament to both the ease and safety that this sail arrangement can give that sold us on this part of the sail plan. At this moment in time we are going through the design and installation of the traveler that is required for good sail tension and control while the tack or jibe is in-process. The image shows s design that we are considering. The key is to keep reasonable tension on the sheet as the move across occurs. It is often a surprise to people to find that a self-tacking Jib only has a single sheet which rises vertically up the main mast to abour 2/3 height, which sets the radius of the track. To ensure a smooth transition the electric Rewind winch can loosen the sheet a few inches and re-tension it once the shift is complete. It is still a question as to whether the traveler car will have control lines or simply use pin stops to hold both the furled center position and the extended unfurled travel extents.
