VG18 Question for Jacques

Post by Jeff »

This question came in through our email system last night: "good morning, I write from Italy; my name is alberto. I read on the internet that to register the vagabond vg 18 to the micro class you must specify when purchasing the plans this option in order to obtain the variant of the plans to port the length of the boat to 18 feet, ie eliminating the two inches in more. moreover it would be advisable, in my case, to use the metric system. How can I possibly buy the plans by specifying all this? I await the information requested; kind regards" Jeff

Shorten the VG18 by 2" is easy but where did you see that a different plan version is available?

We must cut 1" off the bow. I can help with a sketch if needed. The forestay is about 5" aft of the bow, all what you cut is a sliver of wood. I say 1" because for the Micro Class, the hull length 5,50 m, is measured at 70 cm above the WL. At that level, the VG18 length is 552 cm. You have to cut less than 1'!!

There maybe be a problem with the bow angle. Ask a measurer if they care much about. If yes, we must also cut a slice from the transom or scale by 2% which is easy in metric. The plans are available in metric.

Posted by Jeff: "Thanks for the info. My fear was born from the fact that for a few inches, so less than one, I would not have been able to get the certificate of measurement to participate in the regattas. The lines of vagabond 18 hit me a lot, with the linear and clean bow and the possibility of regattas to the boat would be a real shame. Without stirring up controversy in this regard, below is the link where I read about the possibility of plans for the micro class, if I have not read poorly: http://boatplans.cc/bateau/vagabond-18/

So, if I reduced the plans by 2%, in the metric system, at the time of construction, would this reduction allow me to fit into the micro-class measurements? Thanks again for the information, I apologize for my English. alberto" Jeff

Don't apologize for your English, it's fine.

That web page is written by Christine Marchand. She is knowledgeable about boats and likes our designs. She is correct that only a small change is required for that design to fit in the Micro Class.
I have European designer friends who drew boats for the Micro class but Until today, I never noticed the bow angle requirement.
Check the link I posted, it's an Italian web site.
Can you please ask the class measurer if the bow angle matters and if they are strict about the transom cut?
The VG18 side is a little steeper than what they show.

Yes, scaling in metric is very easy: multiply all dimensions by 0.98 and it is scaled 2% down.

JM, I think he got it from the page on the Vagabond 18. It says "If you want to sail in the Micro Class, the boat can be shortened 2" with a very simple change at the bow. We will include that modification in the plans on request."

It does imply a bit that the plans are modified from standard if requested.

Posted by Jeff: "I asked for information directly from Micro Class Italia via e-mail: I asked them if the vagabond vg 18 model could be fine by modifying the measurements in the construction phase and if the model had the requirements for the class; I await news from them and will contact you again in the future. thank you so much. alberto" Jeff

I can quickly draw the cut bow but it is the first time that I see the transom side height requirement posted on the Italian site:

Look at the back, the 0,50 m slanted red line.

Another potential problem is the bow rake, the 0,25 m red line. The VG18 does not fit that.
The VG18 was designed 15 years ago and the rules may have changed.

Once I get a reply about those two measurements, I will draw a "cage" and try to fit the VG18 in it.

From email: "Hello, in Italy it is 8.30 in the morning; below is the link with the rules of the Micro Class with the text in English; the text in Italian reads as follows: "The Length of the Hull measured 0.70 meters above the waterline does not it must exceed 5.50 meters and the average freeboard must be no less than 0.60 meters. ... " I will try to have detailed information, but I think that the vagabond could fall without major problems in the class; obviously my knowledge in this sense is very limited and most likely I like the Vagabond 18 so much that my eyes see no limitations, even if there were any. Thank you for your availability and kindness, alberto

Those rules work or can work with minimal changes but I am worried about the bow angle and the transom angle. To cut one inch of the bow is easy but the bow angle is a problem.
