Book – “A lighter ton” – New Zealand racing yacht design in the 1970s

A new book out by Kiwi Richard Blakey is truly exciting for those interested in performance yacht design.  There is even a wooden boat angle.

A Lighter Ton – is the story of how a bunch of tremendously talented boat designers, mostly from New Zealand revolutionised yacht design through the ’70s.

Almost month by month, International regatta by International regatta new and radical boats from Sweden, Denmark, England and New Zealand challenged the status quo with boats that were exciting, cheap and for most of the first part of their developments were built of wood.

As a teenager drawing boats on any available piece of paper I followed the developments like rooting for a sports team.  Radical new designs from Bruce Farr (towards the bottom of this list), Paul Whiting, my favourite Laurie Davidson, Murray Ross and some of the early Greg Elliot designs.

Dynamic change … boats that could hang in upwind against the old heavier types from Sparkman and Stephens  and Dick Carter and the newer heavy but less heavy than before boats by Doug Peterson and Ron Holland.  The older boats focussed primarily on upwind sailing and left an unexploited area in terms of downwind performance.  Existing boats were “bogged down” and would only plane briefly when there were waves to surf on.  The new boats could plane freely.

A lot of the potential was also because of the New Zealander’s skills in building in timber.  This photo is from the bow section of Mr Jumpa by Farr

Internal bow construction of Mr Jumpa - Farr design in the timber era.

The structure presages composite yacht design with a rigid skin made up of three layers of timber veneers supported by close spaced stringers on the inside.  The rest of the structure is fairly minimal because of the skin rigidity – a few ring frames a couple of full bulkheads and basic bunkfronts and cockpit sides and tops to stiffen up the structure.

Mr Jumpa was sponsored by a NZ wool company … that wasn’t allowed to sponsor using quite its own name.  “Jumper” is an antipodean word for woollen sweater or pullover!  There was also Swuzzlebubble (sponsored by a soap company) and Red Lion (named for the logo of a brewery), Rope Runner (a sailing rope company).

This is a lines drawing for Newspaper Taxi by Whiting.  The chap that built my first custom built racing dinghy, Ian Bashford, was racing on it out of Middle Harbour yacht club in the late ’70s.  It was on a mooring visible from the main road.  Its wide stern, bow down trim (without crew and to cheat the rule) and super thin racing dinghy like mast were radical.  In this drawing you can see the distortions of the side panels of the boat to fit the rule which was forever being evolved to try and make this new style of boat less competitive.  The powers that be should have just accepted the new concepts as the rule collapsed under the weight of amendments and compromises.  And the boats that people want to sail went this way anyhow.

Yacht design has been rarely quite so interesting!  I recommend the book!
