2014 Dragonfly 28 — Chichester, England

A 2014 Dragonfly 28 at Chichester, asking $166,374 through Multihull World. Quorning Boats has built folding trimarans at Skærbæk, Denmark since 1967, and the 28 — in series since 2009 — carries the family yard's signature plainly: the Swing Wing system folds 21 ft of sailing beam down to berth width from the cockpit, without tools, so a three-hulled 28-footer pays for an ordinary monohull slip. The model ships in three rigs — Touring on aluminium, Sport and Performance on taller carbon — and this listing does not say which; establish that first, because it moves the money.

The price needs a hard look either way. Our shelf holds no exact sister, and the nearest cross-check is unflattering: a 2015 Dragonfly 28 in Touring trim asks $129,600 — a year newer, $36,774 less. The shortest rig in the range explains part of such a gap, not obviously all of it, and the listing data here carries no condition notes and no inventory to weigh against it. The premium is the broker's case to make; we have not surveyed her.

So the first door out is that Touring sister:

Where the instinct is hull age over Danish pedigree, the other folding-trimaran lineage answers at the same size — a 2021 Corsair 880, seven years newer for $12,626 more:

And up the ladder without leaving the coast, a 2018 Farrier F-32SR in south-east England brings four more feet of boat for $55,876 further up:

If it is the Swing Wing pedigree you came for, those three numbers are the negotiation — and this is the one to survey first:
