Swift/2

Plans, Swift/2 - 114 EUR Purchase

Swift/2 is a very fast and light canoe for training, competition and touring for one or two paddlers.

The rounded bottom with just a hint of V means a very small wetted surface and an easily driven hull. She is more tippy than canoes in general, but not excessively so: anyone with a little paddling experience will soon be comfortable with the stability profile. In the hands of competent paddlers, she is exceptionally fast and maneuverable.

Swift is designed to be built as light as possible without sacrificing structural integrity. A builder with a couple of light boards (fir or cedar), minimizing epoxy usage may reach 14-15 kg and still have a canoe that can handle bumpy landings on stony banks.

A couple of Swift's were built for multi-sport competitions. This is what one builder has to say (my translation):

"A year ago I built a Swift for competing in multi-sport events. The canoe is super and the fastest in the entire multi-sport circus. In spite of the low stability we paddle safely in rapids and in quite rough seas".

 

But as often with successful newcomers, there is talk of new rules, after successful lobbying from the old established manufacturers – meaning that Swift may be disqualified from some competitions. We will know soon.

The first builder had a few comments:

"She has been raced by the Naturguiden Adventures (Jonas Andersson/Peter Alvarsson). I noticed the increase of beam, Think it is a good thong. Mine was built 580/71 and it is fun to race, tracks well, but on a meandering river you have to be alert and plan your turns – but then it works to 100%! I do not know how others do but we lowered the seats to increase the initial stability. Another thing we needed to add was a good adjustable foot support aft."

Well documented!

The building of the first updated canoe was very well documented by Kristoffer Ahlin och Patrik Olsson, noting costs, hours spent and experiences in a comprehensive pdf-reportpdf-fil with photos. There is also a project planpdf-fil with adjusted times for those who want to know the scope before committing, compare with their own projects or is just curious. Here is a launching report.

Plans

The plan sheets contain the information needed to build the kayak/canoe. Station molds, stems and construction details are full scale. For kayaks the recommended cockpit size is shown half scale with offsets for a full scale drawing and advice on altering the size. On the plans you will also find advice on how to shorten or lengthen the craft. Lines and construction drawings are in metric scale 1:10.

Swift/2 ritningsblad

The illustrated step-by-step building manual is in Swedish only, but it is available online in English: it covers all steps in detail and will guide first-time builders through the project.

Update 2007 – new rules

The Swedish Canoe Federation has now after consultations with the major players decided upon a new set of rules for competitions with kayaks and canoes. The new rules disqualify the fastest canoes – the original Swift/2 is not allowed in competitions where the organizers have chosen to play by the rules. As often such new rules are conserving – manufacturers with investments in outdated technology, hull shapes, materials can postpone the future yet another decade or so.

For Swift/2 it means that the beam had to be increased from 74 to 81 cm, noticeable in two ways: the new Swift/2 is not as fast as the old, and it is significantly more stable. To minimize the speed loss I have maximized the waterline length, meaning slightly more directivity and slightly less maneuverability.  Not a problem for experienced paddlers but beginners may have to put a little more effort in tight turns

The overall consequence is that the difference in performance, shape and looks will be flattened out. The advantages for Swift will still be that a wooden hull is stiffer and lighter than a composite one – I believe that Swift will still be the fastest canoe around, albeit with a smaller margin (luckily the rules committee did not buy the demand that canoes in competition must weight at least 25 kg to be allowed!).

Hej

Skulle Swift/2 kunna användas som roddbåt med slide och långa åror?

Ja det bör gå utmärkt - skrovformen är rätt nära idealet för rodd. Jag har ju förstås inte funderat på roddapparater när jag dimensionerade, så det kanske krävs lite småjusteringar för att sådana skall passa.

Jag paddlade http://www.blackriverrace.se med sonen i helgen. Jättekul men redan från början insåg vi att man inte kan sitta i en hyrd alucanadensare om man har ambitioner ;-)

Kikade på Kanotförbundets regler och de som är publicerade 2010-05-24 är:

C-2, max längd 650 cm, inget breddmått och minvikt 14 kg.

C-2 turis, max längd 565 cm, min bredd 14,3% av längden och min vikt 25 kg.

Gamla Swift/2 klassar alltså fortfarande in som C-2 medan nya Swift/2 klassar in som C-2 turist om man väger upp den till 25 kg. Fast monterad kärra, sitsar och fotstöd får räknas in i vikten.

På Black River Race paddlar alla i samma lista oavsett om man sitter i en ICF-racer, en Pouch faltboot eller en turistcanadensare. Göta Kanalloppet använder uttrycket C-2 turist i klassindelningen. Hur gör andra arrangörer?

LarsM - Är det sliding-rigger, eller slide-säte du funderar på?http://rowingforpleasure.blogspot.com/2008/03/sliding-riggers.html

Jag har planer på att bygga en Swift i framtiden för att använda både med paddel och med sliding-rigg.

Gunnar - Det är en Piantedosi Row-wing dvs slide-säte som var planen. Hur går det med Swiftbyggandet? Mitt projekt är fortfarande en plan.:)

Hej Björn

Har haft kig på Swift 1 og 2 for deltagelse i kano løb under ICF i bla DK. som jeg læser deres regler er det kun max. længde (c1 =5,2m og c2= 6,5 m)og Min. vægt (c1=10 kg og c2 =14 kg). (ingen krav om bredder ). samt et krav om at der ikke må være konkave linier i spant og vandlinier.

Spørgsmålet er derfor om du stadig har og sælger tegninger for den oprindelige SWIFT 2 (b=74 cm)da den umiddelbart virker til at være en hurtigere båd.

Kunne god tænke mig at bygge den med 4 mm gran og Carbon beklædning for at komme så tæt på de tilladte 14 kg som muligt.

Mvh

Peter

Jag har ritningar till den ursprungliga Swift/2 – skriv en kommentar i beställningsformuläret om du vill ha den.

Tänk på att kolfiber inte är ett automatiskt recept för lägre vikt. Kolfiber har lägre densitet än glasfiber och får därför större volym för samma gramvikt och drar följaktligen mer epoxy för att mättas. Om du bara byter glasfiberväven mot motsvarande kolfiberväv kommer vikten alltså att öka.

För att få ner vikten bör du dels ha en lättare kolfiberväv och dels minimera epoxyåtgången genom t ex vacuumbaggning.
