DRAGONFLY Trimarans User Forum

Hi Mark

I needed advice for folding mechanism from Quorning recently.
They asked me to send some pics to analyze the problem.

I got quick a valuable answer.

I used the Mail-adress aftersales@dragonfly.org.

kind regards

Hei Martin I had the same problem with my DF920e. I demounted the windows, removed the rubber gaskins and applicated Sikaflex 552 to fix the window in the frame. I will also use sikaflex to glue the window to the hull. Before appliying Sikaflex on the aluminium frame, you have to put primer on the a...

Hi Wombat
Schlechter Zeitpunkt, um einen DF zu kaufen. Die Dinger sind derzeit heiss begehrt. Die Boote, die auf dem Markt sind, sind preislich wieder reicht gestiegen. Ich wünsche Dir viel Glück bei der Suche

LG jerry99

I removed the amas of my DF920e with the help of 1 person.
The amas were heavier than expected and the center of gravity is quite in front, about 2/3 from stern.

I had north Sails 3Di Sails with carbon/Kevlar laminated sails. Great sails for performance and trim, poor for durability. It is no big problem for the moment, but it is the beginning of the end of life of the sail. If not repaired quickly, water will ingress and the delamination will increase. Take...

Cool!

I will install a Dometic sink with cover.

Dear Fritz
Thanks for your comment.
I solved the problem radical: cut out the whole inner ceiling. I will replace it wit a insulation, for the places where further access is needed, I will cover, so in future I do not have to remove the whole ceiling by water ingress.

Ask Qourning after sale. They know best how the ama has to be reinforced. Can you post some pictures from the Damage? Maybe an advice can be given.

This is a severe damage. Did you ever run aground sideways?
To repair it properly it needs reinforcements rectangular to the box. My advice go to a well renowned boatbuilder and ask for a quote. It will be expensive to repair, but then you will be on the safe side.

That’s a lot of output, and a lot of weight and bulk on a boat the size and payload of a DF920. What equipment do you want to run? My 5 bed house rarely gets up to 4Kw of use. Would a smaller, lighter unit not meet your needs? Dear Martin I want to be independent for 4 days and be shure to load m...

The Plywood in front of the cabin has rotten (black). I guess, the water is entering from anchor locker. There, at the bottom, on each side is a tube laminated where the line for furling the headsail on one side and the headline for the genacker are lead through. Silly, this is the deepest point of ...

The handrails on main hull are leaking. The right side I managed to demount after removing the plywood cover. But on starbord, the foremost screw is hidden by the inner headliner. I tried to remove the headliner without destroying it. But I have any clue how to succeed. Has anybody removed the headl...

Hi guys, although the only way to keep the prop under water under all conditions is to switch to an inboard diesel :-) I would recommend the 15 hp ultralong shaft motor for safety reasons: due to electric tilt and starter even my wife ( 69 yrs, 46 kg) is able to operate the motor . she did not mana...

Does anybody know the weight of one ama from a DF 920 Extreme? In manual is noted it needs two persons to mount or demount the amas; preferably three. Considering a normal person can hold and lift about 30 - 40 kgs, I estimate 80 kgs for one ama. Or is it more and I have to ask Arnold Schwarzenegger...

Hi Folks This summer I was out by 30kts wind and 1-1.5 m waves. I had to learn the outoboarder Honda 10 was to weak to hold the boat in wind. Also I had to go out of the cockpit to tilt the motor up - nasty. Electric tilt would solve this problem - this option I found only in Honda 15. My questions:...

as far as I know you should never (!) apply the mast pin when you are sailing.
It's for raising and lowering the mast only.

Have a good one

Hey Holger
Thanks for your fast response.
So, fold and unfold only in conditions like described in the manual

Kind regards

Has the pin in front of the mastplate another function than for rising and lowering the mast? When I grind in or out the amas, the mast is poorly stabilized by the loose backstays, the mast is wobbling. I think, when the bolt is placed for sailing, the mast is laterally fixed by the bolt on the cabi...

Well, I've have had my lesson with the adjustment of the tension of the waterstays last week. I had the impression the Amas were swinging too much in moderate waves. So I shortened the waterstays on one side for two turns - far too much, how I had to learn: Grinding out the Ama, I gave too much load...

Thanks Bo
This forum is really helpful for newbies.

The item was discussed in 2008, but I haven’t find an post answering my concern. On my DF920E it is nearly impossible to winch out the Amas without distorting the winch handle! Yes, I checked: no yammed lines, backstays loose, secure pin released… I guess too much or too loose waterstays. The po...

Hi Martin
Thank you for response. I considered to buy a kräutler electro engine I skip this idea: too expensive. Now I consider to buy a Honda generator.

Fest Chiara
Thanx for answer.

I think, I will also repair with a carbon sock. So I fix The broken tiler just to give form, then I pull a carbon Sock over and laminate it. I guess the repaired tiler will be more solid than the old version.

On my trip yesterday my tiler cracked. Happily it was near the harbor.

Now I need replacement.
Does someone a drawing or plan with measures for the tiler of a DF920(E).
I think tilers of all 920 are same.

Thx for support

:) Hy folks Thanks for your help. So I think the height of the cabin is as in my X-99. Not really a problem, but often I am remembered, when I rise my head a little bit fast. Well, for speed you have to renounce by comfort. kind regards I bought a DF920E, SUI-118. Heigh in Cabin is ok, I am happy w...

I am thinking to install an electric Generator on a DF920E. I consider to buy a Fischer Panda 5000i.Neo. Has someone experience with such an installation?
Any comments?

Hi

I am looking for a trailer for DF800. Is there someone who can tell what model?
Maybe also pics?

Thanx for your help

Hi
I am considering to buy a DF920.
What is the height of the main cabin?
I am 1.80m and so it should be at least 1.85m for some comfort.

Thanks for answering.
