Does anyone got a polar diagram for DF1000 or any else DF?

If the speed is not measured with a gps, I will first incriminate the speed sensor.

they didn't mention the boat type so far, I can't find any information to know if it's a DF

Many thanks Mika, that's exactly what I needed. I noticed that your rudder head is fixed with 2 bolts screwed directly in the plate thread from the lower part. On mine I get only one bolt (the front one) tighted with a nut under the plate.. I think my system has been a bit modified, I have to figure...

Since I own my boat (3 years) I noticed an important play in the rudder system. As I got many things to replace and improve first, I didn't pay to much atttention to this issue. It's time to get it right. I take note that: - I need to make a quarter turn on my steering wheel to start a change direct...

Thanks Mika , excellent job, very helpful as I'm filling a MOCRA rating application for my boat and some DF1000 specs were missing to me. For this matter I'm wondering which is the "real" weight of my boat, as yours seems to be pretty much in the same configuration as mine, do you have som...

I installed an electric Jabsco lite flush in my DF1000 and it works great.

see picture.

I'm not sure it is a Dragonfly, amas looks assymetrical as the DF 28 and it's definitely not one...

My DF 1000 is now equiped with a 29hP D1-30 Volvo with a 3 blades Flexofold 16x11. I am fully satisfied with this improvment, engine run much more smoothly and quietly and the speeds recorded with a normal sailing loaded boat, with the center board fully up and calm water are : 6,1 kts at 2000 rpm 7...

I use a light 3,2 kg fortress for daily mooring, stored permanently in the forward storage. I have also a 10kg Kobra for longer mooring which isn't the best choice, althought it's an excellent anchor, because it doesn't fit good in the anchor fitting and so have to store it in the aft storage. I wil...

I got the answer from Quorning, now the bolts use the same system of the 920, bolts are pushed in from the top and the side locking screw is then secured with loctite.

I feel more confident with this improvement.

I got m'y new 18mm bolds ordered to quorning, I am surprised to find a side safety screw on thé lower part of the pins.
Is it normal? I have to say I have never taken down these bolds on my boat...

Mika,

did you get your new carbon wheel?

you're right Steve, if the hinges got more thickness they would last much longer.

thanks to all for your helpful answers. I ordered oversized 18mm bolts to quorning (original are 16mm). Nicolai told me I can not use a regular drill bit when it can not centre in a oval hole. Normally they make the holes bigger with a rotating file and a hand file. Works will be done this winter wh...

Anyone can tell me the type and size of propeller used on a DF 35?
I would also be interested to know the motoring cruising and max speed.

Thanks in advance

I expect to change my swingwing wires and asked quorning to supply me new ones. The problem is that I have first to take down the sheaves boxes and send the the whole system (wire and box) to set the new wire. Except if I am ready to use Norseman terminals that avoid the taking down of sheaves boxes...

I am in a refit process of my DF 1000 and got several items to change or repair. I need your expertise on some specific issues: Do you know if the four beam hinges are symmetrical (front-rear and port-starboard)? the front ones work loose and the starboard one has approximately a 5mm side movement g...

Mika I'm interested in your project, but I'm afraid a carbon wheel is too much expensive for me.
Do you have any idea of the cost and delay?
What will be the wheel diameter? Will the design allow to keep and mount the same autopilot?

Olivier

yes I can believe you, the original wheel is quite ridiculous and really unconfortable when you stay hours steering in windy conditions.

I found on Ebay a 81 cms Lewmar Commodore wheel but I'm wondering if it will fit on the current steering axis. Do you have any idea, I'm quite far from my boat?

I'm seriously thinking of having change my old Volvo 2020B . It's really noisy, loses some oil, and definitely not enough powerful for a choppy headwind condition. Furthermore, most of control instruments doesn't work anymore (tachymeter, alarms,etc..). As my game field is now the Méditerranean sea,...

Mika, I also would like to have a bigger wheel but I expect to increase the actual diameter by only 20 cms. You have now a 100 cms wheel, do you feel happy with it?

thanks to all for your replies, I have already disconnected the wallas heater, I don't need it as the boat will be used in mediterrannean sea and only during spring and summer seasons.
I have to remove this too.

Can anyone tell me what this round button is used for ?

I just went through the previous posts on this topic, I now have replies to my answers. Replace and adjust on water is possible and the way described to give a proper setting seems easy to do. I will try to keep accurately the same lengh on the new ones than the actuals as the folding/unfolding is q...

I got my new set of waterstays and I'm wondering about the replacement and setting process. What should be the key points to take care ? Should the boat be on the ground or is it possible to operate on water? Do I have to set the new ones exactly with the same lenght of the former ones? I mean, plus...

Thanks for your help.

I found the knot drawing in the Selden document.

do you have any picture of the dyneema knots ?

Mika ,

I would really be very grateful to you for contacting them for me.

Hi Mika, I'm a new DF 1000's owner and I expect to change the whole set of trampolines. your local supplier seems to be very cheap, are you fully satisfied with your new set's quality and do you feel as confident with it compared to the original one? Do you have any idea of the delay for making a ne...
