I scaled various boat dimensions from the line drawing. I scaled both the depth and LOD to determine the multiplier to use. Is this something that you would like done if the info is not available from primary sources, or do you only publish info from primary sources?
147 SA m
186 SA j
334 SA tot
If you are content with scaled dimensions I will provide them as the mood strikes me.
Wow! Awfully kind of you. There are a number of factors that MIGHT make this difficult.
1. Yes, I only publish rig dimensions that are read off of a sail plan or published in a brochure.
There are other sites where rig dimensions are published and I look them up occasionally when I don't have any for a specific boat. I never use them because I they are so full of obvious errors.
But I COULD just add a note saying "these rig dimensions are dervied form blah blah blah....."
2. It seems like you already know that every designer or builder has different definition of LOA. So one would need to be cautious when using this as a datum, (which I see you haven't done). This is further complicated with the presense of a bowprit etc.
3. I assume, in this case, that IY and IJ indicate dimensions for the staysail triangle. Currently I don't have fields in the database in which to put them, though they could be added in the notes section.
4. As you may have noticed, the quality and resolution of drawings that you see here vary widely in quality.
But when it comes down to it, ALL dimensions should be taken with a 'grain of salt'. And as long as people are made aware of that, having a somewhat consistent way of calculating sail area would be very useful. Once basic rig dimensions have been entered, tot(calc)SA comes up, as does SA/disp. ratio.
As you may have noticed, there is a separate SA field that appears at the top. This is used when only a total SA figure is available, but is not used in, nor derived from any calculations.
Just out of curiosity, what program are using to do this?
Sorry to be so long winded about this I just thought that it might be helpful to explain something about the basic setup.
So by all means. Be my guest. If your numbers seem to be in the ball park, I'd happy to use them with the aforementioned caveat.
