You might find the following useful if you want to use Michlet.
I assume you got the file from this site: http://www.cyberiad.net/michlet.htm
As Leo prompts " ..... please read the manual...." It is contained in the download as html files.
Some useful hints.
1. Create a new folder called Michlet.
2. Create a new folder called Godzilla.
3. Place a copy of mlt807w.exe in both folders.
4. Place a copy of alleg40.dll in both folders.
5. Place a copy of godzilla.bat in the Godzilla folder.
6. Copy the Flat_Hull_850.mlt file I have attached into the Michlet folder and rename in.mlt. Likewise for the God_850_in.mlt to the Godzilla folder.
7. Double click on mlt807w.exe in the Michlet folder - it should
bring up a new window.
8. Now press <shift> <R> - it will change the window, Now Press < t >
- it will produce resistance curves. Press <Esc> twice then < y >
and it will close the window. You will note there are a whole lot
more files in the Michlet folder.
9. To use Godzilla open the Godzilla folder and double click on
gozilla.bat. This will open two windows - the small one is the .bat
10. Now press <shift> <G> and godzilla will go to work optimising the
hull that I have as the start for your 850lb canoe. You will see all this is in metric so you have to get used to that.
11. Press any key after a few minutes and this will stop godzilla.
12. Press <shift> <R> and < t > to see the resistance curves. Press
<Esc> twice then < y > and it will close the window. You will note
there are a whole lot more files in the Godzilla folder.
13. You can compare the performance of the optimised hull and the
your Flat_Hull comparing ship-output-by-speed.mlt in both folders.
You can just open them with Notebook. Notebook will then recognise .mlt
files as text. I load the data in these text files into Excel for analysing.
If you have any problems getting going then just post.
I see that you need to think about the best compromise for 2-up and 4-up depending on the events involved. A 4-up canoe with WL of 20ft is going to be beamy. A coxless 4 is about twice that length and you can bet it would be close to optimum for the power level of 4 fit men. With that length it will be thin but 20ft will be fat.
