I have put a building sequence with notes for the GIS up on Flickr
http://www.flickr.com/photos/boatmik...7602972202430/

Actually it is all the pictures from the Duck Flat Spring School and I have separated out the GIS ones so you can follow the narrative.

I have also gone through and written comments about each of the major steps.

So most of the hull construction is covered as is some of the hollow box section mast. There is a round solid one for those who like a dose of tradition!

Great boat and great photos of build sequence

It's very helpful for builders

I've finally updated my GIS website, with a bunch of new photos, a better build description, a few movies and all photos are now clickable to open as a larger size in a new window.

I'd love any feedback, broken links, or typos or whateve!

Thanks,

P

Hi Midge,
Couldn't find any whateve!'s

, nor typo's but then thats in the people in glass houses basket and tried the links they all worked.

So as for feedback

both entertaining and informative.

Only one problem I wanna build a GIS and its all your fault.

Cheers Mike

It seems to me that the index down the right hand side makes the pages extremely long. For example, the 'exceeding expectations' link fills about 2 pages of text, then I have another dozen or so pages which are blank. Not sure what is happening there.

Its certainly inspirations stuff! Nice site.

Hello you down under! I try to get used to all the different mails, blogs etc. about th GIS, but now I found this site!

A few weeks ago I bought the plans for th GIS and last weekend I started building it.

Reading the instructions, I came up with a few questions, mainly due to my lack of knowledge of boatbuilding terms in English / Australian, I guess.

Can I sent the questions to this site?

Also I will keep a blog on the progress. Maybe it can be connected to the GIS site?

I make a lot of pictures of the building of the GIS (some 5 of each step) . If any of you you are interested, I can change them into another format (right now: RAW, some 3 MB each picture) and size.

Hope to hear from you soon

Hi SOLing - if you like there is an option to put the building story up here. Then the questions (from both you and us) become a permanent part of the whole thing.

The only real limit is that if you want to have the images on this site they have to be smaller than 800 x 600 pixels and smaller than 100kb. See the "manage attachments" button below the window when you post a reply to this.

The other way is to have them some place like flickr and put in a link.

eg - this is one of my picture sets on flickr
http://www.flickr.com/photos/boatmik...7602972202430/

And this is one of the images - they give you a choice of around 5 sizes. This is the medium one.

If you want other people to see your post this is one of the best places. Some of the building stories have had big numbers of readers. Though there are other places on the net like this too.

But you would be welcome if you want to do it here.

Just start a "new thread" and call it what you want. I can correct things if you have any difficulties.

Best wishes
Michael

Now, SOLing ...

May I ask - why are you are called "SOLing".

(they are a great boat! But there may be another reason)

Best wishes
Michael

SOLing · #54 12th Feb 2008, 07:00 AM

Hello Mike,

thanks for the welcome!

my name is SOLing for at least tw reasons:

SOL as for sun , because every time I think about boats sailing knots etc I feel sunny inside (my wife thinks I am a bit crazy. I guess she is right in this respect).

The second reason is for the soling indeed. the best boat i have sailed in, al though at that time the weight of the crew gave us only an advantage in very light winds. That has changed, now we would be best at a force 5. But no longer a soling in sight

I will start a thread and move the content of my blog there: to maintain two sites will be too much.

The questions I will do in another thread

kind regards

ab

Howdy Soling - I used to race a Soling when I was a teenager (and we sometimes won races when the helmsman did particularly well (or listened to me)). They were never really common in Australia. The great thing was that the owner let me take the boat out by myself - so I could use it whenever I wanted. Not a bad thing for a 15year old.

He then upgraded to an Etchell - which he was very proud of - so my school holiday sailing fleet was reduced in size.

With the forum...

It would be great if the questions were in the same thread as the building - that way people can see the relationship of the questions to the building.

Have a look over the Eureka and the PDRacer threads and you can see how they grow in a natural way - with building stuff, questions from the builder and the people who drop in.

But please don't feel any pressure - just do what you would like and we can help it as best we can.

Best wishes
MIK

Hi

I have a question re. building a mast, boom etc. for either a GIS or PDracer.

I know that wooden mast/boom would look better but since I would need to buy all the material anyway and plane down all the wood somewhere - and if I ask the carpenter to do that for me it cost more- aluminum then is not that expensive.

So I was wondering, what kind of aluminum tube would I need for mast and boom for:
a) GIS and
b) PDracer

I can get the tubes anywhere from 20-80mm and wall thickness 2; 2,5 and 3mm.

Thanks

Boatmik · #58 5th Mar 2008, 01:54 PM

Howdy Koala,

This is a bit of a problematic area for me. I know aluminium can be so much easier and lighter for the overall weight of the spar (it can be heavier at the top though), but there are two big problems and one smaller problem.

1/ It cannot compare for performance - the bending characteristics of the PDR mast and the GIS Lug Yard in particular are responsible for a very large part of the sailing performance of the two boats.

The bending when a gust hits the boat is just right to prevent the boat heeling too much and allows it to accelerate rather than stalling.

This effect is the single most important improvement in sailing boat performance in the last century.

So I make use of it in all my boats - just like a well tuned raceboat.

Using aluminium would require a bit of trial and error to get something like the same response.

The PDR mast would have to be of two different sections like a Laser mast - a thick one at the bottom and a thinner one about halfway up. The lower one to be strong enough and the upper one to be flexible. Then you have to join them and make sure the change doesn't affect the shape of the sail.

2/ Aesthetics - untapered aluminium masts look really bad. If you used a thin and thick tube for the mast on the PDR it would be acceptable in appearance.

But for the Goat which is such a beautiful boat it would look terrible as the mast is quite big at the base and if it goes to the top. For the Goat Mast (and all lug rig masts) it is only the appearance that is the problem as that big stick is not supposed to bend much.

And the lug yard and boom look nice too when tapered. Pic below.

This pic (the best I could find) shows how the taper of the mast matches the thickness of the yard at that point keeping everything in nice proportion - it keeps the feeling that it is continuous.

TOUCHDRY · #59 26th Mar 2008, 04:52 PM

Hi

I have been looking at the GIS as an option to build this winter. I realise this question is one of those 'how long is a piece of string' questions, but what is a ball park cost of materials (including timber and rigging)? In short- How much could I get it on the water for, do you think? Having never built a boat (but worked plenty with wood), I'm on a learning curve with the cost of marine ply and gear etc.

Boatmik · #60 1st Apr 2008, 12:33 AM

Howdy Touchdry,

Don't go for a ball park figure - get a quote. Email or phone the Duckflat mob.

You can get contact details from
http://www.duckflatwoodenboats.com

They have it all worked out in a spreadsheet.

I know I'm being a bit of a party pooper taking the mystery and discussion out of it - but it's the sort of thing I do.

Be aware that you don't necessarily need to get the whole lot straight up.
