Release Date: 1/15/2011


The Dragonfly 1000 is an elegant trimaran from a family of boats designed by Borge Quorning and manufactured by Quorning Boats of Denmark. Its evaluation is against the averages [in brackets] of nine other trimarans with overall lengths ranging from 32 to 34 feet is as follows:



Displacement: 2.28 tons [2.25 tons]


Length Overall: 33.00 feet [33.10 feet]


Length at Waterline: 30.00 feet [31.87 Feet]


Sail Area (Main plus genoa): 647 sq. ft. [713 sq. ft.]


Displacement-Length Ratio: 84.33 [70.08]


Sail Area/ Displacement Ratio: 34.94 [38.99]


Beam between outrigger centerlines: 23.75 ft. [24.55 ft.]


Base Speed: 10.55 knots [11.29 knots]


Texel Rating: 103 [98]


Bruce Number: 1.48 [1.56]


Stability Speed: 17.47 Kts



The boats used in the average are the Farrier F-32 and F-33, Hughes D-32, Pulsar 33, Aquarius, Contour 34SC and Trimax. (See details of these boats in Multihull Data on this site; free Multihull Comparisons now available.)


The Dragonfly 1000 is near average in displacement, but the light side in sail area, and gives up nearly two feet in waterline length in comparison with the boats listed above. The result is that she is about .74 of a knot below average in Base Speed. Her modest sail area gives her about knot advantage in stability speed. Nonetheless, she is very similar to the Farrier tris and falls in the racer category in Charles Kanter's Multihull Classification system. (See Classifying Multihulls in the Technical section of this website.)


Several differences between this boat and Farrier's are worth noting. The outrigger folding system is of the "Swing wing" design, folding horizontally backwards, whereas the Farrier system tucks the outriggers into its armpits (sorry Ian). The Dragonfly 1000 has a pivoting centerboard rather than a daggerboard. It has an inboard mounted engine under the cockpit rather than an outboard. And the upper hull shape is flared more to make internal accommodations more roomy. The overall impression is one of concession to cruising (note the company name), while retaining the power and light weight needed for successful racing.
