The boiling battery probably has a short in one cell, effectively turning it into a 10 volt battery which is being overcharged, hence the gassing.
Replace them both.

I have turning blocks with snapshackles on my reefing lines - just undo the snapshackles from 1st or 2nd reef points and hook them into 3rd.

According to various internet sources, they are more or less the same.

That might be part of the problem, although the same quality is used on my main halyard. Loads on the main halyard are lighter I guess. But it's true that I sometimes open the easylocks without reloading the line first. Tensioning the fold-out line, releasing the lock and then winding and whinching ...

Unfortunately it turns out that the 8mm dyneema line I used has its sleeve completely 'eaten' by the easylock in just one season. The easylock seems to grip only the sleeve which eventually will tear and expose the dyneema core that starts slipping through the lock immediately. My chandler showed me...

Under previous ownership my 920 has capsized on the same stretch of water under similar circumstances (fast spinaker sailing without being overpressed). The previous owner was convinced that something like a hookup with a lobsterpot had to be at the base of that accident, though no trace was found. ...

Why isn't it? Looks like a DF 28 to me. Tinkerbell RET ?

Ipe Piccardt Brouwer

One is an F-32, 'Tresoor', built by Tom and Cora Siemerink.

The other is DF-28 ''Triple blue", property of Jaap de Geus.

I happen to own a picture of Triple Blue flying the hull coming of a wave. Can't post it here unfortunately.

Last winter I made a modification to my outboard (Yamaha 9.9) that was suggested on the f-boat site:

Haven't had enough time to test it's effect in full, will keep you posted. I already have the hi-trust propellor.

Ipe Piccardt Brouwer

In my experience raising and lowering the mast is perfectly doable when you closely follow Quornings instructions. However, I always do it with the boat in the water and the tip of the mast on a ladder onshore. Carefully check each step and don't try it in a blow. The hard part is indeed getting the...

Hi Pippo - welcome to the club!

There are no specific DF events that I know of but the Catamaran en Trimaranclub regularly organise events where Dragonfly's are well represented.

Take a look at the website www.ctcnederland.nl en maybe I'll see you at the rondje IJsselmeer in may next year!

You will always need the B+E licence. You need it when your car is lighter than your trailer and you need it when car+trailer>3500. Assuming boat+trailer are heavier than 1750kg, one of each conditions will always be met. So good luck bribing your driving examinator (sorry about that silly bigotted ...

Ipe Piccardt Brouwer

I'm very interested.
Anybody knows any details?
Trailerable?
Accomodation size?

I just took the most expensive 8mm my chandler carries, he calls it 'racing gold' for a reason I think ;-) It makes a big difference: I used to have to walk/jump on the trampoline to close the last centimetre. Now I can unfold completely just by winching. Last part of folding in, especially the seco...

My secret wish for an electric winch disappeared after replacing the 10mm swingwing line by 8mm dyneema. Reduces the required effort by about 50%! I guess the smaller diameter means I will have to replace it a bit sooner. It's worth that. I have the drill bit (but never bought the drill), you can ha...

I don't think a True Wind Angle of 35 is a realistic expectation. A tacking angle of 90 degrees, TWA =45 degrees, is more likely (quite neat, actually). This will result in an Apparent Wind Angle of 30-35 deg. Tacking angle should be judged by compass, not GPS. TWA of 45 degrees/ tacking angle of 90...

Nope, speed is just fine here.

Ipe Piccardt Brouwer

Well, yes, you're right. But what to think of 'These 2 previous hits might have weakened the backward beam at the connecting point of the blocking bar. Causing it to brake through the beam when the full force came on it.' ?

Clarification needed!

Ipe Piccardt Brouwer

If I read the report correctly, it was not the aluminium tube that broke. The tube remained intact but it was pushed through the beam. In other words, the back wall of the beam caved in under the pressure of the safety strut. Maybe because of previous collisions, after which only the front beam was ...

Ipe Piccardt Brouwer

...other sources tell me they doubt this story. They think that the primary failure was the swing wing line. Folding occured, then fracture and total collapse. Let's hope that investigation will clear this up!

Ipe Piccardt Brouwer

There's a report of the incident by the owner of the unfortunate ship in our dutch multihull club magazine 'CTC nieuws'. He was sailing at a speed of 11 knots in wind about 20 knots, 1 reef, slight to modest wave action. Suddenly a spontaneous breakage occured in the front starboard beam, shortly fo...

Ipe Piccardt Brouwer

I was told the knot is essential, because if the centerboard is lowered to far
down, the board gets too much free play in its case.....

Ipe Piccardt Brouwer

Welke haven? Ik lig in het regattacenter.

Ipe Piccardt Brouwer

Rumour has it that there was a structural failure other than broken waterstay or forgotten safety strut. Possibly a broken beam or hinge.

Last wednesday a friend saw it passing by on a truck heading north on the A7 so i'm guessing its headed for Denmark for investigation.

Ipe Piccardt Brouwer

What a mess!

http://www.knrm.nl/30waar_wij_zijn/10re ... icle=13979

Anyone have an inside report? Looks like the forward beam is connected to the hull but no longer to the float. (Part of) the rear beam is still attached to the float.

Ipe Piccardt Brouwer

An impressive project!

I am also intrigued by the new rudder (stek-klappruderanlage).

A nice wannahave for my 920 as well, which makes sailing in shallow water a lot easier.

Ipe Piccardt Brouwer

Does anyone of you sail his DF35 singlehanded?
How hard is that? Can you moore and unmoore her alone? Unfolding, setting sail etc?

Ipe Piccardt Brouwer

I had that one fixed some time ago. It results in a wet locker but the water will not pass to the cabin, it remains in the locker.

Ipe Piccardt Brouwer

I recaulked the frame yesterday. Now waiting for rain... Traced another leak to the gas vent that was retrofitted in te starboard cockpit locker. This vent scoops water at higher speeds and was probably not sealed well. Has to wait till boat is out of the water. I wil try the talkpoeder trick to tra...

Ipe Piccardt Brouwer

I understand you didn't remove the frame to recaulk it?

Ipe Piccardt Brouwer

I'll check that as well.
How hard is it to replace the aluminum frame caulking?

Ipe Piccardt Brouwer

Thanks for your reply. For leak 1 I will do some more testing and then probably start with replacing the caulking. Concerning the second leak, I also suspected the cocpit drains, but they seem to remain bone dry during sailing. But yesterday I noticed that there is also a fair amount of seawater in ...

My boat has water collecting right down the companionway next to the freshwater pump (port side). It seems two different leaks are responsible for this. 1. Rainwater dripping from the inside of the aluminium frame of the companionway hatch. This does not occur when the sprayhood is fitted, so I thin...

Ipe Piccardt Brouwer

I am very happy with my integrated (AIS included) Raymarine C70 plotter, flushmounted in the port bulkhead. Even if it becomes obsolete, it will be just as usefull as it is now.
As a backup I have paper charts, and a complete NW europe Navionics set (just 20 euros!) on my iPhone

It's probably a 28 with 4 feet virtually added.

I saw the new 28 at the Boot show yesterday. I think Quorning succeeded in designing an attractive boat for starting trimaran sailors. It has a slightly smaller look and feel than a 920. It lacks the nice woodwork. But it is also cheaper and lighter, and a lot sightlier than the adjacent Corsairs. I...

Ipe Piccardt Brouwer

I'm quite sure that it is a backup system. So the primary system failed first. The line broke, or someone accidentally opened the wrong clutch.

28ft = 8.55m

Where will they fit those 5 berths!?

Ipe Piccardt Brouwer

I agree with Larry: in normal use, the beam should not hit back on the strut. It might happen in a heavy seaway (though I never noticed). No oval strutholes on my 10 years old DF920.

Might it be that your swingwingline is of the stretching type? Manual suggests using Spectra.

Ipe Piccardt Brouwer

Recently I entered a lock together with 30 monohulls with a force six straight on the stern. It was not easy. However, I discovered that it is crucial not to let the boat gain any speed. If it goes faster than 2-3 knots, reversing the engine will result in a lot of cavitation and little braking powe...

Ipe Piccardt Brouwer

Great footage, David!

I notice that you have a sea-me active radar reflector mounted on the stern pushpit.

Is that a satisfactory arangement?

Ipe Piccardt Brouwer

Ted, which pins id you replace? Untill now I was assuming everybody was talking about the locking pins in the aluminium safety-tubes behind the rear amas. Now you mention smoother opening of the amas after replacing the pins, which I don't understand. Do you mean the pins in the swing wing pivots? (...

Yes, we did notice!
