For the first time I introduced the deep chested V-d type of planing hull into the canoe world. The following year, 1933, I went with Roger de Quincy, a keen young canoe sailor, still at Oxford, across the Atlantic in the old Empress of Britain with two canoes: Roger&#8217;s Valiant and my East Anglian, both sister ships.

Stewart had challenged for it America had, until 1933, defeated all comers. Having shown that a boat could be designed to two distinct rules, and still win, we had meetings with the Americans asking them to change some of their rules on condition that the Royal Canoe Club of Britain changed some of theirs so that we could have an International Rule for canoes all over the world.<\/p><cite>UFFA FOX &#8216;SAILING BOATS&#8217;<\/cite><\/blockquote>\n\n\n\n<p>These meetings resulted in the first iteration of the International Rule<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>Fortunately, the Americans saw the wisdom of this argument, and we soon roughed out a rule which would develop a wonderful canoe.

Both slip and canoe triggers could occur, which is why the types were designated as<\/p><p>Class V, A and resp. B, depending on rig design. In 1931 it was time to see the C-canoe born.

Most photos depicting period sailing canoes show a mast with a bend in the top section. I suspect that <em>Zenith<\/em> may have had the &#8220;crooked&#8221; mast but this was replaced some time before 1953 (I have a photo of her with her current mast from 1953)<\/li><li>&#8220;&#8230;..<em>until 1924, wire stays were used on the &#8220;mainmast&#8221;, but this year a canoe, designed by Magnusson, appeared with completely unstayed masts and this canoe turned out to be quite superior to the others<\/em>&#8230;&#8230;<em>Magnusson&#8217;s types in class 3 B are now almost the only ones who participate in races in this class.\u00a0with completely untamed masts and this canoe turned out to be the others quite superior.<\/em>  It appears that  only Magnusson designed boats were being raced after 1924. As <em>Zenith<\/em> is defiantly a Sven Thorell design from 1913 this information about Magnusson&#8217;s boats adds to the evidence that <em>Zenith <\/em>was built prior to 1924.<\/li><li>Of particular interest is the photo, believed to have been taken by Thorell, it shows a fleet of canoes racing, and all have conventional shrouds and do not have the unstayed Magnusson rig that was popular after 1924, so this photo is probably pre-1924 and shows boats with a very similar hull shape and mast position to <em>Zenith<\/em>, especially the boat closest to the camera.<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"861\" height=\"614\" src=\"https:\/\/www.pegasus18.com\/zenith\/wp-content\/uploads\/2021\/05\/b-class.jpeg\" alt=\"\" class=\"wp-image-568\" srcset=\"https:\/\/www.pegasus18.com\/zenith\/wp-content\/uploads\/2021\/05\/b-class.jpeg 861w, https:\/\/www.pegasus18.com\/zenith\/wp-content\/uploads\/2021\/05\/b-class-300x214.jpeg 300w, https:\/\/www.pegasus18.com\/zenith\/wp-content\/uploads\/2021\/05\/b-class-768x548.jpeg 768w, https:\/\/www.pegasus18.com\/zenith\/wp-content\/uploads\/2021\/05\/b-class-816x582.jpeg 816w\" sizes=\"(max-width: 861px) 100vw, 861px\" \/><\/figure>\n\n\n\n<p>So, the confusion about the modern &#8216;B&#8217; Class rule and the pre-1931 &#8216;B&#8217; class rule has been addressed, <em>Zenith<\/em> is a IIIB design and  built before 1924 as the Magnusson designed IIIBs were the only boats being built after this date.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">RCC  Canoe Rules<\/h3>\n\n\n\n<p>We know that <em>Zenith<\/em> was registered as International Canoe in 1935 as  apparently she qualified as RCC &#8216;B&#8217; Class canoe.<\/p>\n\n\n\n<p>Andrew Eastwood &#8216;s &#8220;From the Rob Roy to the International Ten Square Metre Canoe&#8221; has a comprehensive section  that covers the the 1894 B class rule, the 1914 B class rule and the 1929 B class rule.

It was suggested by Ron Head (who took the photo of <em>Zenith<\/em> in 1953), when I spoke to him just after I  took custodianship of <em>Zenith<\/em>, that as there were so few International Canoes sailing in the 1930s <em>Zenith <\/em>was invited to join the fleet to increase numbers. This seems a sensible scenario and the 23mm extra beam was ignored.<\/p>\n\n\n\n<p>Reviewing the RCC &#8216;B&#8217; Class rules has solved one mystery. There are two 1\/4&#8243; bulkheads fitted (5&#8217;1&#8243; from the stern and 4&#8242; 6&#8243; from the bow). These are clearly a later addition as there are numerous screws that go through the hull into the bulkhead frame, and the quality of the timber used is below that of the rest of the hull. It would appear that these were added as a way of complying with the 1928  RCC &#8216;B&#8217; Class rule that states &#8220;<em>There shall be two transverse bulkheads of wood on each side of mid-length, but not within 3 feet (914mm) of either end of the canoe<\/em>&#8220;<\/p>\n\n\n\n<p>To summarise, <em>Zenith<\/em>:<\/p>\n\n\n\n<ul><li>was built to a  <a rel=\"noreferrer noopener\" href=\"https:\/\/www.pegasus18.com\/zenith\/2020\/01\/10\/sven-thorell-and-sol\/\" data-type=\"URL\" data-id=\"https:\/\/www.pegasus18.com\/zenith\/2020\/01\/10\/sven-thorell-and-sol\/\" target=\"_blank\">1913 IIIB design by Sven Thorell<\/a>;<\/li><li>was built at some point between 1913 (when her sistership <em>Sol<\/em> was designed) and 1924 (as only Magnusson designed IIIBs were built after this date);<\/li><li>is a &#8216;sailing&#8217; IIIB design with 10m<sup>2<\/sup> of sail area (as opposed to the &#8216;racing&#8217; IIIB with 12m<sup>2<\/sup> of sail area);<\/li><li>arrived in the UK on or before 1935 when she appears in the  UK register of International Canoes;<\/li><li>was considered to be the equivalent to a RCC &#8216;B&#8217; Class, despite being slightly beamier that a &#8216;B&#8217; Class;<\/li><li>was modified to comply with the RCC &#8216;B&#8217; Class with the addition of two bulkheads.<\/li><\/ul>\n","protected":false},"excerpt":{"rendered":"<p>As I wrote in the Useful Sailing Canoe links I don&#8217;t want to replicate the history of Sailing Canoe development as there&#8217;s plenty of information out there already.
