Hi Rolf
No problem at all.
Welcome to join our FB group "Svenska Flerskrovsvänner" mostly in Swedish but growing more and more international and with many Dragonfly sailor-members. Possibly you can pick up tips and inspiration and no problem at all to ask or post in English.
Cheers!

Hi Rolf, That's correct no boom vang since it's rarely needed. In such a fast tri you never go deep downwind and the speed bends the apparent wind forward. A good setting could be on max upwind you put the traveler in the middle and take home the sheet hard. When turning to reaching you always start...

Stefan Kolmodin

Hi Rolf, I have the same furler and it's quite clever. In your jib luff there should be a thin release line for the quick release. Attach this to the thin cable attached to the hook in the top part. Then you attach your gennaker halyard to a open hook and this to the schackel at the top part's outsi...

Gransegel has of course all kinds of cloth for all purposes. It’s critical to communicate to your sailmaker how you use your boat and what your expectations/preferences are. The goal is to identify the right balance between performance and durability which is individual to all sailors/boats/circumst...

My racing laminate main from Gransegel is into season 13 now and still competitive - with a lot of care, some repairs and carbon fibre tape.

Stefan Kolmodin

Hi Roger, A long way from Cayman but you could always check with Mats Johansson at Gransegel here in Sweden. Loads of experience both as Dragonfly sailor and sail maker. Gransegel are market leader premium sail makers for cruising/racing multihulls over here and have done a lot of sails to DF28S. Ch...

Stefan Kolmodin

Investigated it further and its empty. I suspect it's supposed to be used for a holding tank. Since the boat never had any installed and that I threw out the toilet immediately the hose is a gonner too. Shaving 2 kgs off the scale :-) I'm installing a lower point in the stem for the waterstay to the...

Stefan Kolmodin

Hi Dirk, I can recommend you to give Gransegel here in Stockholm a call. They are market leaders here and specialists with more than 25 years’ experience in trimaran and Dragonfly sails. They know every Dragonfly model and mast profile by heart. Not the cheapest but certainly best value for money if...

Stefan Kolmodin

Hi,
From the stern and following the keel there's a heavy duty hose with woven cover laying below the floor in the center hull of my boat. It seems to be originally installed by the yard - does anyone know what it is/for what purpose it's there?

Stefan Kolmodin

Check with Elvström and previous owner.

Stefan Kolmodin

My guess is that if you lift a DF in the bow (centre hull) it'll be top heavy and turn mast down. I Think best way with a crane available is: 1. Lift the boat from centre bow to release the mast top from the bottom. 2. Separate and save the rig from the boat first. 3. Fold one ama and pull/roll the ...

Stefan Kolmodin

While you're at it - original centerboard and rudder are heavy as hell - replace with Carbon fibre one's

Stefan Kolmodin

Indeed, must have been a strong wind, locked sheets and wrong turn (upwind) to flip it without gennaker. And don't mention the resque completely destroying the boat!

Stefan Kolmodin

I'd go to Gransegel every day of the week!

Stefan Kolmodin

I agree with Anders, I'm always crash jibing and have never broken any battens (round carbon rod) or anything else. Never let the main out to more than barely touching the side stays. I guess if you let the battens bend over the sidestay they may break when crash jibing. Remember always try to jibe ...

Stefan Kolmodin

Check with Elvström?

Stefan Kolmodin

Must be strong enough to tie dyneema ropes to the bowsprit base plate. No big forces with no movement/momentum. BUT these will possibly interfere with my huge gennaker coming down!

Stefan Kolmodin

What model did break the alu-bar?
I feel safe enough with the trampoline rope and the alu-bar.

Stefan Kolmodin

My 800 SW have a diagonal alu bar behind aft AKA preventing the AMA to fold in case of trampoline failure - should be ok safe.

Stefan Kolmodin

Support the boat on props (?) and pull out the trailer. These are good since you can lift the boat higher with them and get all of the cb out and also easier to get the trailer back in place again. http://www.seaquip.se/sortiment/mb-stottor/mb2/

Got the pricelist and a DF25 Sport ready to race with some comfort stuff like cushions to sleep on sprayhood and cockpit tent making it possible to cruise with - it's 133 406 €

Stefan Kolmodin

I agree, the 25 is a daysailer possible to sleep in and the 28 is a family cruiser possible to race with.

Stefan Kolmodin

The really smart Lagun table worked fine in my previous boat - SK55 SWE-7. Would be interesting though to someone trying to use the toilet under the front V-berth talk about hunching

Stefan Kolmodin

They have put it in port berth to get enough floor space for one foot. In a pic with Jen Q and one other guy they can't sit normally opposite to each other. It's a narrow boat! https://www.baadnyt.dk/nyheder/trimaran-video-interview
Too small and expensive for me.

Stefan Kolmodin

I've asked both Quorning and Dragonfly Sweden about the price without any answer (yet) but here's my estimate: Cruisng with main & jib = 70K€ which equals 87,5 K€ incl VAT (Swedish) Sport version +20% (guess) = 105 K€ Screecher = 3500 € Gennaker = 4000 € Electronics = 2500 € Trailer = 7500 € Rac...

Stefan Kolmodin

Still missing a lot of sail area and she's not designed to fly her center hull according to Jens "The floats will have 160% volume. This means the boat can easily fly the centerhull, not that this is the purpose, as the boat will be fastest when the centerhull is just airborne." I Think it...

Stefan Kolmodin

I agree - nice look - but more speed and comfort in my old DF800R which makes the price tag extreme.
Would have liked a bit more:
- Space in the cabin with four ok berths
- Sail area for performance
Just one ok berth in the front in this boat (?)

Stefan Kolmodin

Hi Good tricks to save on these expensive lines - starting with buying it 2-3 meters too long - are: 1 When you notice substantial wear at the clutch (should take 1-3 seasons using Double Horizons tip to take off the load before releasing) you can swap ends of the halyard to get a new part of the li...

Stefan Kolmodin

Tack Christian,

I found some good articles about this and have been field testing.
You can do a lot with an active rotation trim - increasing sail depth in light upwind for more power by rotating more and bending the battens and the opposite in strong wind.

Stefan Kolmodin

Hi, I'm sailing a DF800R with a non furling gennaker on what I think is an original part bow sprit from Quorning (check with their after sales or your local rep). A simple aluminium spar (ca 1,8 m) hinged to an easily mounted attachment bolted to the boat. Very strong dyneema lines holding it in pla...

Stefan Kolmodin

Hi Phil,
Always nice with bearings for smooth handling - you should find sheaves for the mast foot easily, changing on roof top is a larger (and more expensive) operation. If not already done I recommend to start with changing to new round dynema lines and blocks in the reefing points.

Stefan Kolmodin

Hi,
I'm wondering how much to rotate the mast. For me it's both a security (the long unsupported top on the 800R mast bends a lot with wrong mast angle) and a performance issue. Does anyone know?

Stefan Kolmodin

Used to...
Anyway they will be there this summer too since I prefer to sail rather than removing stripes - two new "homemade" jibs to try out asap

Stefan Kolmodin

But left them on the mast?

Stefan Kolmodin

Thanx Larry,
Been there done that?

Stefan Kolmodin

Thanx Steve,
This is on aluminium so less scary with heat

Stefan Kolmodin

Since new DFs have those maybe it's a good idea to check with Quorning?
My own boat needs new ones as well.

Stefan Kolmodin

I'd like to remove the red original stripe/tape on the side of the mast (aluminium). It's been there since launch 1995 so a bit hard to remove. Anyone out there got a tip on how it's best/easiest done?

Stefan Kolmodin

The fastest Dragonfly ever?!

Stefan Kolmodin

I want a more performance (vs comfort/luxury/cruising) oriented model this time. I love sailing my 800R but would like a Little more cabin space for the family. Just four ok berths and simple cooking fac and toilet. I light boat need less sail area and smaller rig which makes a less expensive boat a...

Stefan Kolmodin

When reefing with the furler the area is reduced but the sail profile normally get deeper - the opposite of what you want in strong wind - so for upwind sailing you can only reef a couple of turns keeping an ok profile and also a large genua is made of thinner cloth than a hard wind jib. My freinds ...

Stefan Kolmodin

The original set-up you describe is good but in light wind you love an X-large gennaker. Upwind in light wind you can hopefully use the Code 0 with the right design and that you have good halyards. In really strong wind it's great to have a smaller jib to match a fully reefed main for balance. I've ...

Stefan Kolmodin

Hi Mathias,
I have been sailing on and against DF28 Sport.
Next sails I'd go for is a larger gennaker of 95-100 m2 and a smaller self-tacking jib (hardwear kit needed can be bought from Dragonfly Sverige) for strong wind or easy handling while cruising.

Stefan Kolmodin

Of course there's loads in the forestay but not necessarily higher than on a monohull. Every load has an antagonist holding it in place which on a tri is a without a lead keel on a momentum arm hence smaller righting moment fore/aft. Where the balance is is individual to every construction. My obser...

Stefan Kolmodin

I disagree, a stay in line with the mast/boat center doesn't support much sideway load. Also most gear on cruising boats are substancially oversized. If you want to be super safe - oversize everything. If you like to race/go fast with a light boat check what gear other boats of the same model are us...

Stefan Kolmodin

I think the higher loads are mainly due to the trimaran's higher righting moment sideways. If you talk forestay/furlers trimarans haven't got higher righting moment fore/aft rather less due to no lead/lower weight so on this stay the loads should be lower than on a lead sailer.

Stefan Kolmodin

Hi Dirk, Sounds strange to use the reef. You'd have to remove the reef line from the leech to avoid having cunningham at the back as well and normally the first reef is too high to work well as cunningham trim. If you have a ring or eye low in your main luff for cunningham, can be added to used sail...

Stefan Kolmodin

No wire or torsion line in the luff. For a gennaker it should be separate from the sail. Otherwise it's no gennaker shape. Normally a gennaker for furling are a bit more flat than a non-furling for easier furling but with the Facnor trick you can furl also a deeper sail without problem. On my DF800R...

Stefan Kolmodin

No problem furling an assy. What you need is an anti-torsion line to furl around either with a top-down furler like this from Selden: http://www.benns.se/gennakerfurler-gx15-p-21431-c-110.aspx or with a bottom-up furler with an intermediate furling line to middle of luff like on this film on Facnor ...
