Thread: Start Building Another Dutch GIS

Lovely pics Ralph! Your boat looks awesome and your sail is a very good one too. The design is almost exactly the same as mine. However yours is setting better than mine because my yard isn't stiff enough. Your yard looks just right in that light breeze. How did it look in the stronger breeze?

Congratulations on another GIS getting wet!

I have athwartship "bunks" at the extreme ends and to the after side of the after "bunk" I mounted a 9 inch wide rubber roller. It is set to barely contact the bottom when the rig is out of the water; the weight is carried by the bunks. At launch, I just lift the bow a few inches and the roller takes the weight and allows me to easily shove the boat back into the water. No part of the trailer gets wet except for the tread of the tires.

Howdy MAM,

Would be great to have some pics of the business parts of your trailer ... I think it will be useful to a lot of people.

Hello Ralph,

just came back from holiday and saw the launching! Congratulations on the launching! Nice pictures! Nice boat!

Great to have three GIS in the Netherlands. No other area has such a density of these beautiful boats. And all in the south as well!

Nice touch to have a red colour! What caused that colour? the success of our soccerteam? or does the Mothership have to fit in?

I already am looking up my wooden shoes. The windmill will be more difficult, as Joost and I noticed last time. Looking forward to an official meeting of the RDGB (royal dutch gis association) with coffee, speculaas and some real refreshments.

greetings,
ab

I am not shure about the yard yet. It is quite stiff, but seems to have sufficient flex in a stronger breeze ( using full bodyweight on the side ) .
The stif boom and loose footed sail seems to work very well.
This set-up really gives max power on this sail...............but I am not shure if it depowers enough to be comfortable.
I just need to sail a few time more under different conditions to give more accurate information.

Hi Ab,

Indeed, also the mothership has a dark red coulor.................but initially I was going to the shop to buy a "mid grey" ish paint. That was sold out, but then I saw this coulor and bought it since I wanted to start painting that afternoon. Now I am very happy with the result.

There is a windmill in Terheijden, my hometown.............but no water close to it

And we need to sort a date&time to have our RDGA autunm meeting asap!

Ha ... thanks for looking.

The windmill is not essential - and it would be wrong to put a hole in a dyke for a picture opportunity!

Be aware too that with the growing number of Goats in the USA there might be limited time to be the first group to get three together!

Two other "birds eye view" pictures from my GIS. You see the good and powerfull aerodynamics of a well set-up balance lug rig.

Good looking boat, and a good looking sail!

Is your sail from McNamara Sails in the UK? It would be interesting to see you boat sailing alongside Joost's and hear your impressions of any performance differences from the differences in sail cut and spar stiffness you have incorporated.

I'm also going with a sail with 3 leech battens as opposed to the 'three full length battens but leave them out concept', so it's good to see you getting such good shape out of your sail.

I'm also keen to see a capsize test and hear how your boxed in central console and drainage tubes through to the transom work in practice. I have some pictures from Richard Harvey of Blanche capsized, so it would be good to see the equivalent pictures for your boat!

All the best, Ian

Hi Ian,

it's McNamara's, indeed. Looks like a great sail to me, but you need to take in consideration that it has a quite hard-finish cloth and the leach battens are a bit in the way if you want to rol your sail around boom and yard. So it is less easy to handle, like most high performance sails.

Joost and I will certainly do some comparing together. Perhaps nex few weeks. I personally hope not to have any practice using my drain-tubes ...............
But I will do a capsize test, if the weather is right.
I'll keep you updated

Best Regards
Ralph

Hello Ralph,

Good to finally see your boat in the water! The McNamara sail seems to set rather nicely on the very stiff spars. For sure we need to compare the rigs to see whether any lessons can be learned.

I am also interested to see the draintubes in action.

Again: Congratulations!

Best regards,

Joost

When you get a bit more wind you will find the interesting dynamics of the hull at higher speed.

Mark, who made your sails summed it up really nicely ... the boat just seems to go faster without any real feeling of commencing planing.

It is a characteristic of the OZ racing boats like the NS14 and Taser which have quite low drag hullforms - as my experience was in those boats they had a lot of influence.

REally happy to see that nice sail on your boat.

I think you are going to have a hoot with the Goat.

Hi MIK,

I was also surprized on the tacking abillity. I needed to tack 1,5 mile against this unpredictable wind on a quite narrow canal. Under these circumstances steering balance, keeping speed after turns and acceleration in gusts and shift are more important that the actual wind-angle you are making.
Also important are the ergonomics within the design; are you able to move around, keep your body-weight in the right place, no mess between main and rudder controls a.s.o.
GIS does this VERY well and gives you exactly the right feeling and feed-back to keep her moving. For me GIS fits me like a glove.......I can hardly wait to sail her another time under better circumstances.

Seems to me you really did an excellent job with this design.....and it is worth a well made sail.

Regards
Ralph

I'm meeting with my sailmaker tomorrow and have to weight the pros/cons of a roachy sail with leech battens vs the simple sail as designed. Will a sail with leech battens still flake okay and be able to tie up with the yard and boom as a neat bundle?

Hi Clint
As my sail has 3 leech battens permanently sewn in I can answer this one. Yes, it does. What I do is lay the boom and yard side by side, with the sail still attached to both of course. When you do this you will see straight away that you need to make one fold to create a square and then you can just roll the sail around both boom and yard together and slide them into your bag. Easy.

If you just roll from the boom, you will be left with a neat enough package, but the ends of the yard and boom will not coincide, so you would need a much longer bag
