i love this! i'm looking into the dragonfly 25. do you think they will come out with electric motor option? or is it possible to order one custom with an electric motor? thanks
Four reasons: Double potential speed when reaching; minimal heal angle; less draft so can sail in shallower waters; trampoline zones allow easy storage of paddle boards and kayaks. The smaller trimarans may also be easier to trailer.
Trimarans are an evolutionary dead end. They pitch pole. To stop this, the amas have to have enough buoyancy to carry the weight of the whole boat. At this point, you effectively have a catamaran with an overly large central pod that drags in the water. A bridgedeck catamaran is the obvious solution.
Yes, that is probably true for a big cruising trimaran/catamaran. But there is a reason that nearly all cruising multihull are trimarans in this size. This is the sweet spot for a cruising trimaran. You can put it on a trailer, and it fits in the marinas. Unless you fly a hull on the catamaran, the trimaran is faster.
@JacobBohmeDK exactly. @Ron-dx9wq We are not referring to trimarans like a MOD70 here. Modern cruising trimarans have great buoyancy near the bow. The buoyancy volume needed depends on the ratio of sail area to the length of the boat. For example, the Performance series has an inverse bow on the amas to increase the buoyancy. The amas are also wider at the bottom and narrower at the top. Before the bow of the amas ended before the bow of the main hull, nowadays, some folding trimarans have the amas bow as forward as the main hull or even more forward to help with the couple (Force X Distance). Stay curious!
Tris are not an evolutionary dead end. Trimarans have greater form stability than cats. All of the fastest sailboats in the world are tris. The dynamics and drag depend on the design, size, conditions, etc. A tri can be more hydrodynamically efficient than a cat because the floats and main hull are optimized for different needs. Regarding pitchpoling, a Dragonfly 28 probably is not going to be racing the Southern Ocean at 30 knots. That all said, catamarans do make practical cruisers.
@@JacobBohmeDK You seem to be confusing cruising with trailering. Agree a trailerable trimaran is a lot more practical than a trailerable catamaran (ignoring cost and complexity). To me cruising means boats that rarely or never go on a trailer, but stay on the water cruising the world more of the time. Maybe the meanings are different in different languages/cultures?
Hmm, I wonder how I managed to circumnavigate the earth with my Farrier F36, and occasionally sailed over 20 knots hours on end on a beam reach near the Seychelles. The ability of the autopilot over 12 knots restricted the amount of sail I could carry so one should consider the loadings on the rudder at high speeds.

@sams0blu yes, it is. Please contact your local dealer or Jorn from the factory to get a quote for a DF25 with an electric outboard.
Excellente présentation Martin, qui présente clairement les avantages de ce magnifique trimaran! Bravo!
Love the dragonfly boats
Le Dragonfly, tout un trimaran dont tu nous fais connaître ses qualités hors de l'ordinaire. Ça nous donne vraiment le goût de l'essayer!
Merci! 😊
Nice fresh innovative design!
Merci Martin, Excellent documentaire.
Thank you 🤗

Seems to be trending that way.
1:15. HA HA HA!!! Isn't that what they said about the 'Titanic'?
Material properties makes object float or sink. A design such as having a high number of bulkhead like the Titanic doesn't make a boat unsinkable.
Nice design.. way way way too expensive
How tall are you?!? It doesn’t look like you can sit up straight in the salon!
@ruskerdoo1539 I'm 6'6" ...! Or 2m tall. A lot taller than most people.
I fit but barely. If you are 6'4" or less, you are fine.
