If you ever want to crunch the numbers on just about any boat or compare different boats (mine is missing, no surprise) there's a link here where some guy has put together a data base on about 1300 different models.

He's also got data plots and macros to (attempt to) model what the ideal off shore boat would be, based on the designs of those which have made 1000's of ocean crossings.

So, does it work? Can this be used to pick out the ideal off shore design or to decide between a number of available boats? Can the decision be reduced to a number on a spreadsheet? Does this take all (or some of) the fun out of it?

Can this be used to answer those type of posts that seem to come up every other week or so?

Think about it. I'm going back to the "Seeking Happiness" thread to see what TB and Hog have been up to.

Bastage. I know I can buy an unsurveyed McGregor 26X in Mexico and sail it in the TransPac with no problem, and anyone who says differently is just trying to crush my dreams.

Does it work?

Haven't looked at the spreadsheet - yet - but I doubt it. I could probably (maybe) create a similar spreadsheet with a list of totally unsuitable boats that has made successfull ocean crossings and hence the output will evaluate the MacGregor as the perfect Blue Water boat. There's so many variables involved, that it is next to impossible to collect enough data to be statistically significant. We still struggle with understanding exactly how boats react - Velocity Prediction Programs using sophisticated algorithms, and running on extremely powerful hardware still do not provide the EXACT number for a particular design. So there's still a lot to learn. I believe that is true for desirable characteristics for a bluewater boat too. However I also strongly believe in listening to advice from people such as Hal Roth and other "old salts"? (Including all the grumpy people here on sailnet :D )

Why would anyone consider the opinion of a person who hasn't taken the time to look at the information?

He hasn't done that. That would be a waste of time (like your post was). He's used designs from "Carl Alberg, John Alden, Bill Crealock, Ted Brewer, Lyle Hess, Ted Hood, Al Mason, Chuck Paine, Robert Perry, and several Europeans" to try to get a meaningful model, not a useless one.

the only thing I found missing in this whole scenario?

The skill and experience of the nut behind the wheel.

You're right - I should have lied :D
What I meant was that I did not have the time to verify all the data in there. I did not intend to bash the hard work that obviously has gone into it creating it, but I still think that my comments are valid - There's still a lot to learn!
Sorry for not being clear (English is NOT my native tongue). :confused:

C'Hand...This has been used here before. As I recall Jeff_H took a look at it and trashed it pretty well as a meaningful tool. I couldn't figure it out so I can't comment beyond saying that it doesn't seem to me to be a very meaningful way of deciding on a boat....but I guess some people do rely on the numbers.

The numbers in this spreadsheet just describe the container that is the boat. How capable the boat is must be determined by a lot of factors that don’t lend themselves to this type of analyses. The presentation of the data is interesting and useful as a guide to what is considered normal for a given size boat but thats all it's good for. The devil is in the details and this will not predict your success with any given boat on any given trip.
All the best,
