Davis Yost’s Solo Trippers DRAFT June 2016
David Yost’s original Solo Tripper, 15.5 ft by 30” max, 27” wl was offered as a Fiberglas or strip built canoe in the Canoe Specialists 1981 Catalog, a mold having been made by Curtis Canoes. The hull had flared sides and minimal rocker with a Length to Width ratio over 6.5.
The next year Yost designed the Vagabond, a 14’8”X27.5/25.5” smaller version tripper for Curtis, with 1.5” of the shouldered tumblehome he developed for the DragonFly and 1.4” symmetrical rocker. The abrupt tumblehome required a two-piece mold split along the keel line.
A similar size series set of tripping solos soon emerged for Sawyer, the StarLight, 13’4” X 28/26 and the Autumn Mist, 14’10”X30.5/28, both with minimal rocker and 2” of bubble sided tumblehome with W/L ratios nearer 6. Bubble sides allowed the hulls to be extracted from single-piece but split molds. Seats were height adjustable sliders and rocker was minimal.
DY and Curtis updated the larger Solo Tripper in 1985 with Nomad, at 15’4”X28.5/26.5”, slightly Swede-Form with shouldered tumblehome and differential rocker. The hull has increased stem layout so waterline is shorter than overall length indicates and is now available from Colden infused in carbon with lightweight integral rails. Yost also designed a wood and Dacron 15’ X29/26” solo tripper, Mistral, for Loon works ~1989.
He designed his third “small class” tripper, the Loon,14’ 6”X28/26” and his fifth medium class, the Heron, 15’X29/27” for Swift Canoe ~1990, both bubble sided to come out of split rather than two piece molds and with symmetrical rocker.
In the later 90’s Bell Canoe needed a solo tripper and the Merlin II, 15’X29/27”, DY’s sixth large series solo tripper, was stripped and molded; slightly Swede Form with shouldered tumblehome; the first DY tripper with differential rocker.
Hemlock Canoe developed their Peregrine and Kestrels from Nomad and Vagabond. Both Hemlocks have flatter bottoms and reduced rocker. Initial stability is increased but speed and maneuverability are compromised.
Designed for pack canoe outfitting with low seat for double blade paddling, Placid boatworks’ RapidFire, 15’X27.5/25”, R 1.5/1”, is slightly Swede Form with shouldered tumblehome and strongly differentiated rocker, and was DY’s fourth small class solo tripper in 2005. Placid’s combination of infusion with integral, composite rails significantly reduces hull weight.
DY’s seventh standard sized hull is Swift’s Keewaydin 15, introduced in 2011; 15’X29.5/26.5”, R 2/1”, mildly Swede-Form with bubble sides and more abrupt, stepped, bow rocker. The additional width was added to fit today’s larger paddlers. DY’s new stepped rocker is applied throughout the Keewaydin series to improve forward speed and maneuverability.
DY designed his fifth small class solo tripper for Swift as the Keewaydin 14 over winter 2013-14, featuring bubble sides with slight Swede form, and differential rocker with stepped bow rocker. At 14’ X28”/25”, R 1.5/.7”, it is more efficient at cruising speed than the larger Solo Trippers due to reduced wetted area. Infusion manufacturing with integral foam and composite rails significantly reduces hull weight for Kee 14 which is available as a web seat, single blade canoe and in low-seat, double blade, pack canoe, configuration. Swifts Kee 12.5, new in 2017 will be 28” wide. Reduced Length to Width ratio will compromise tracking and render it more a sport solo.
Ted Bell/ NorthStar Canoes commissioned the NorthWind Solo from DY’s son, Carl, over the same period, the eighth Yost designed Solo Tripper, up-sized to fit larger paddlers at 15.5’ X 30” / 26.5”, 2”/1” NorthWind Solo has slight Swede form and shouldered tumblehome but reduced rocker and does not include the new stepped bow rocker to retain visually resemble to the older Bell canoes in NorthStar’s line. Early NorthWInd Solo hulls exhibit hog, from hurried mold building or applying straight rails to lightweight hulls, so do not maneuver as well as the rocker specs suggest.
The theme throughout the series has been fast and easy tracking tripping hulls, so W/L ratios have been kept above 6, usually nearer 6.5. Over time, the hulls have become mildly Swede-Form as a drafting function of differential rocker and included tumblehome to improve paddler reach across the rails for increased bio-mechanical efficiency. Rocker has increased, become differential and most recently, stepped into the bow to improve forward speed and maneuverability. The hulls are widening as paddlers gain girth, and unseemly reflection of the success of McDuck’s Super Size promotion.
These are conceived as intermediate skill level hulls. Once sized and fitted to the aspiring paddler, they do everything pretty well. DY’s Sport or Touring Series are logical next choices as solo paddlers select more targeted performance for more specific water conditions. cc CEW
