Thread: Jungfraufahrt of the 2nd Dutch GIS

During the maiden trip I made some improvements, because you have to get to know the boat:

- the traveller was removed to the back of the boat;
- the blocks on the boom were moved aft, so first one was halfway the tiller, the second just above the ratchet block;
- the attachment point of the main halyard was moved some 15 cm higher up;
- the downhaul was moved some 10 cm forward, so the boat had less tendency for lee (now the sail was some 40 cm in front of the mast).

During sailing as speed went up, I noticed that there was some movement between the rudder and the rudderhead. That caused some trembling in the rudder. I will see that fixed. Have to look at the rudder and the rudder head to find out what went wrong in building. Best guess is, I took away to much wood from the rudder when planing it to 22 mm. I will see.

Having mainly sailed on keelboats (cabincruisers. racing yachts, Soling etc) and only a little on dingys (Finn, Laser) I learned two important things:

1. donot step on the front seat with the boom, yard and sail in your arms. Donot grip the mast if you almost fall. If you do, you learn how to bail out a GIS.

2. donot step on the front seat without the boom, yard and sail in your arms. Donot grip the mast if you almost fall. If you do, you learn how to bail out a GIS.

Congratulations! Well Done!

Home boat builders throughout the world are in awe...

Do you realize what you have done is so rare, it has nearly become an urban legend? Heck, you will become an urban legend!

Missing a projected launch date - even by almost a year - is not unheard of, it happens all the time. But missing a launch date by being 10 months early? Truly an remarkable accomplishment!

Great job!

Thanks for the pictures.

Thanks, Bob, for your kind words . It is not so much of a problem, when you are the sponsor as well as the projectmanager....In real life I am a normal human being, who, okay, only occasionally, misses a deadline. But donot tell my fellow-partners, please?

greetings SOLing

Hello SOLing,

Great to see your boat launched! Looking very good!

And congratulations with 1 one the greatest accomplishments I have ever heard of: dumping the boat before it has even sailed a single mile!

May many fine adventures follow!

Best regards,

Joost

P.S. We should make arrangements for the windmill photo session soon...

Hi SOling,

Congratulations with your second Dutch GIS "Duyfken" !
The boat looks very nice and this light blue looks very good on it.

Yesterday I had a sail with Joost in his first Dutch GIS; Great Boat indeed !
I also felt it has some lee helm in very light winds, but had a great balans if it picked up a bit more wind. I am trying to fine tune this with an more rigid boom and loose footed sail ( see my building thread )

So I guess now I am the only one in the Netherlands who still has to build his GIS
This third Dutch GIS launching is sceduled Spring 2010 and I am shure I will not get that improved as much as you did.

It seems, as a result of our first "Duyfken"'s discovery, these Aussies are getting back on us with a little GIS invasion

Regards
Ralph

Howdy,

In light wind I think the boat also bow steers a little. Don't know if that is a correct term!

Basically it is the old steering without a rudder trick, but with the rudder in place.

When sailing without a rudder (you usually have to pull about half or a third of the centreboard up too) you heel to leeward and the boat will point up. And to bear away you heel the boat to windward.

I have noticed a bit of this in light winds on Peter's Gruff.

It feels like weather helm but it is not. I am talking about Peter's boat ... might be different with yours.

What it is in light wind ... you are sailing with a bit of wind pressure and then the wind drops suddenly. The boat heels to windward and the bow steers the boat to leeward.

If Gruff is level the helm is very neutral in light winds, but a bit of heel to leeward gives you a definite weather helm and a little heel to windward gives you a little lee helm.

Just something to watch for. It might be a touch of real lee helm too of course.

I think the adjustable outhaul should increase the weather helm slightly as will heeling the boat to leeward in very light winds. Bring it upright as soon as getting up to reliable speed.

Best wishes and big congratulations! I was on the other thread saying it will bre nice to get it launched. Looking at the next thread and it IS launched!

Everything is ahead of schedule on this boat!

Michael

Hello Joost,

it took 47 years of dedicated training to reach this point: being stupid and unbalanced and in a dinghy at the same time! I am sure many more things will happen.

I will send you an PM with my phone number to make an appointment. greetings Ab

Hello Ralph,

thanks for the compliments on the boat. My wife calls the color "swimmingpool blue" as she wants to have a swimmingpool at our house in germany. We will see when that will be build (not if, because she has set her mind to it. She also choose the color of Duyfken...).

It took me 324 hours of building and painting, of which 49 hours were spend on correcting mistakes I made in spite of the excellent plans by Boatmik.

Just keep going and next year we will sail with three GIS in the Netherlands, the biggest fleet ever

regards

Ab

Thanks Mike, for this bit of information. I really need some time to get used to Duyfken, as a skiff together with a balanced lugsail is something different to what I am used to. But I really loved the way GIS picked up speed when there was just a little more wind. And indee, the feeling of lee helm disappeared right away. I will keep all informed on the exiting adventures of Duyfken andher crew (I almost convinced my wife of taking part in Raid Finland next year. Only trouble: she noticed the raid was at sea more or less. I will ask the Finnish organisers for some quieting remarks on that part).

I really enjoyed building the GIS. And I think some more boats will follow. I only have to think of a way of combining building and sailing and working and socializing and ...and..

Greetings,

Ab

Once again I marvel at the internet, to be able to enjoy the achievement of a boat launch from around the world.

Congratulations SOLing on the launch of your DUYFKEN that reservoir area looks to be a beautiful spot for the first sail and thanks for sharing your little misadventure. Did Mik leave out the instructions in your plans that cover ballast?

Cheers
Mike

What is the paint you used? Epifanes?

I used some local paints, the paint just a very good (and expensive, Euro 44, 35 for a litre) exterior paint, which was advised by a Dutch professional painter. I will look up the names tomorrow when I am in Germany and post the names after that.

I liked the way the paint (upper coat) went on, the primer was a bit more difficult, but I think that was caused by the temperature at that time, over 27 degrees C.

The varnis worked very nice and give a beautiful shine.

greetings

Ab

I checked on the paint:

- Varnish: Clou Yachtlack, a danish product, works fine

- primer: Sudwest, local german producer, primer for steel, wood, alu, plastics. Quite thick. I used this, because I haven not encapsuled the whole boat in epoxy. I built my Waarschip in 1973 and just painted it. After 13 years the paint was just fine. Only the varnish should heve been maintained a bit better. So I decided to use the same method. Only I epoxied the sides of the ply, the inside of the seats and the inside of the hull. So I took this primer, as it works on wood as well as epoxy.

- paint: Trimetal Permaline Regule. exterior paint from AKZO. no special boatpaint, but a very good one pot paint. Boot will be inside during the winter, and on land and covered the rest of the year.

I took gloss, which will be changed at the next painting to matt. Hard spots will be more difficult to see then, I hope.

Greetings, Ab

NB we were in maine last november for a wedding of a friend in Augusta, went to wooden boat. would love to sail some day over there. could bring my own GIS then, I guess.
