Je vois ... :D :D :D

Je crois qu'il vaut mieux en discuter sur le chat francais. Ce soir 20:00 UTC sur 'See Naples and then die ...', ca te va?

Incognito, I'm trying to understand and use your spreadsheet but am having trouble. First I copied that data from brainaid web site for the polars of the Beneteau Figaro boat race. That looked to be okay I had no errors.

But when I tried experimenting with it by plugging in data I was using in the race the results didn't correspond with what the race was showing. Did I do something incorrect?

Are there any instructions on the use of the spread sheet? I'm still learning on how to use VMG and VMC.

Thank you

crzycanuk,

There are no instructions. I build this spreadsheet for myself, and then made it available here following some requests.

I suggest to discuss it on the chat of Key Lime at 18:00 UTC.

Regards,

Francois

Bonsoir à tous.
J'ai au début un peu galéré pour comprendre comment fonctionne le fichier de François.
Pour l'adadter à un autre bateau, il faut remplacer les valeurs des cases A10 D7250 de l'onglet Data.
Faire un "Clic droit" sur le tableau croisé dynamique et cliquer sur "Actualiser les données".
Désolé pour nos amis anglo-saxons, mais je suis bien incapable de traduire correctement mes propos en anglais.

Hi Incognito,
I think i have sorted out the use of your spreadsheet. I have inserted the different polars from Brainaids site for various boats. It appears that the max speed for Orange, IMOCA 60 and others stops at 24 knots. I have put the same weather info for 3 boats and they all show 24 as the top speed. I have checked the data and it goes higher than that. WS 33 TWA-137 Course 30 TWD 267.

Cheers

I do not understand what you mean. For Orange for example, my spreadsheet indicates a top speed of 29.49 kts at 131° TWA with 30 kts of wind.

Here is the translation of Serge's post's,

Good evening.
I struggled a bit early to understand how the file Francis.
For adadter to another boat, you must replace the cell values of A10 D7250 Data tab.
Doing a "Right Click" on the PivotTable and click on "Refresh Data".
Sorry for our Anglo-Saxon friends, but I am unable to translate my words correctly in English.

It’s 2200nm and we’re taking the 60ft Trimaran, in the hope we can keep up!
