Comparing Specs

Recommended Posts

Looks a lot like Sailboatdata.com. I think you should give him credit. Someting like this

SBD is used under the Creative Commons License sailboatdata.com (sailboatdata.com) / CC BY 3.0

 

And at least one of the pictures is off my site http://l-36.com/even.php. He provides a link to my site which is nice given he is using a picture off my site.

 

But nice site. Here is my version of the same thing. http://l-36.com/boat_dimensions.php Yours is prettier. Mine has more data sources so you have a chance of getting some confirmation of the numbers.

I like the ability to compare the numbers of multiple boats with the data in columnar form.

 

If you don't know what boats you want to compare and just want to see everything within a certain size and date range, then it is fine

 

On the other hand, finding boats you want to compare is a bit clunky. Say you want to compare: J/35, Schock 35, Thomas 35, and Express 37. You have to scroll though a lot of pages I think. Maybe have the equivalent of combo or drop down boxes to filter by builder and model (shouldn't be too hard, pretty easy query I would think)

Thanks! Yeah it's based on sailboatdata. I love the data, but hated the way it's presented/frustrated by the lack of search and compare features.

 

Good call on the citation. I'm adding it in the footer now. (Your footer disclaiming a lot of liability is something I will probably add too)

I like that your site has multiple sources to search under too. I will definitely be checking it out more.

The query is not hard, but wrangling sending the entire database in a single HTML file makes it really big, which hurts performance.

 

I opted to chunk the results up into pages. I would like to have the search results appear as you're typing, but that's a little ways off.

 

Thanks for the idea about a builders filter. I'll be making that soon.

That looks like a good start. Accurate specs are often hard to find.

 

A couple of problems I run into:

 

1. A lot of the data is 20-40 years old. Many masts have fallen down and booms have broken. Not always replaced with identical equipment.

 

2. "Just because we designed it that way doesn't mean we built it that way!"

 

3. Where's the pictures of the Missus's or little sister's bewbz?

I built a website to find and compare sailboat specifications. I personally, but thought I would share it with the wider community:

 

https://sailboatpages.com

 

Let me know if you like it, hate it, or if I should add any features.

 

Cheers

 

Advanced Search could be a lot more advanced.

 

I'd like to be able to put in ranges for any subset of displacement, SA/D, length, year built.

 

You should allow for quickly searching for other boats by the same builder (like sailboatdata does).

 

Please give sailboatdata credit for the data. Are you scraping their site, or do they publish it as a database now? Why don't you scrape all fields?

Forestay length in a few designs I'm familiar with - Way off.

Just something to fix...

 

If I need a new Forestay, I'm not going to look it up on the interweb.

I'm glad there's some demand for that kind of thing. I've been working on this for awhile and wondered if anyone would find it useful. I will add more advanced searching and filtering options soon (I will make SA/D and Disp. a priority because of your comment).

Most of the data is scraped from sailboatdata (via tools build on http://scrapy.org/) so thanks for calling me out on not crediting them. Fixed that in the footer now.

I used I and J to calculated forestay length: (Forestay Length)2 = (I)2 + (J)2. But that's not perfect, so maybe I need that disclaimer...

I hesitate to give forestay length working off my own drawings!

I would go with "approximate forestay length"

forstay length is handy if you want to call some friends with similar boats to buy some of their old sails.

What differences, if any, are there between this and Sail Calculator?

 

http://www.tomdove.com/sailcalc/sailcalc.html

Woah that site is awesome! Much more powerful than mine (currently mine only does step 1a and 2). I will use it to add some features to sailboatpages.com. Thanks for the link.

 

Some things I really like about it:

  • Filtering by racer/cruiser.
  • The visual color bars to represent the specs when comparing them.
  • The clear explanation of each of the derived calculations.
  • All of step 4 for finding an ideal boat.

Some points of differentiation:

  • Bigger database derived from sailboatdata.
  • Finding sailboats to compare is easier because the searching and filtering step is first.
  • Looks pretty.

You could be perfectly happy using either. But I'm definitely going to use that for some ideas. What do you personally like most about the "Sail Calculator v3.54"?

 

Cheers

It is easy to use, you can compare two boats, you can add your own boat's specs, and you can search for a "dream boat" using different parameters. Riddled with errors, as is sailboatdata, as are any numbers from the manufacturer frequently. They are very responsive to corrections, as is sailboatdata.

 

I don't like that you can't include draft in a "dream boat" search. It's a really important factor in some places.

Errors to me are one of the biggest issues with these sorts of tools. I'm going to add a feature that allows anyone to suggest updates to the information. I'll probably want admin powers to approve or reject spec changes suggested by users. Maybe add a per sailboat forum to comment and discuss proposed changes. I hate sign ins, but that seems like a necessary evil.

 

I agree, the "dream boat" feature is really great. A huge point of difference for The Calculator.

.. wrangling sending the entire database in a single HTML file makes it really big, which hurts performance.

 

The entire database in .xlsx form of sailboatdata.com, sans images, is only about 1.5MB. (I know because in 2014 Alex W generously sent me his version.) 1.5MB is about the size of a single photo.

 

I consult Alex W's old .xlsx file all the time, filtering, sorting, and graphing on whatever fields I like. IMHO there are only two disadvantages to an excel database: drawings are missing, and you can't easily post a link to a single boat's info. The first disadvantage could be relieved by adding a field for image links. (The second disadvantage remains unaddressed.)

 

If I wanted to publish a new user interface to the database at sailboatdata.com I'd first discuss it with the owner of that site. First to ask if he would like to host it on his site, and second to get his blessing to use it elsewhere if he didn't want to host it.

You're right, the size of the database isn't the issue, but searching and filtering a dropdown menu in HTML is hard, so I opted for the list/pages instead. I do need to add a "sort by" feature though. Do whatever works for you! Do you like the select box on http://www.tomdove.com/sailcalc/sailcalc.html better? I like it, but I don't think it's good for browsing or discovering boats.

 

You're right about contacting sailboatdata, they have a right to know I'm using data derived from their site. Maybe they won't mind. I made this service because they haven't added any features in a really long time. Maybe this will spur some changes on their end.

 

Do I need to license the data from sailboatdata to do something like this? I like to think information on the internet wants to be free, but that's probably controversial.

An Excel or csv file is all I really want/need. Then I can slice and dice the data any way I choose.

I have an Access DB created from the US Sailing Critical Dimensions list. It has a query to compare boats based on SA-D, Disp-L, etc. If anyone wants a copy PM me.

Here is my version of the same thing. http://l-36.com/boat_dimensions.php

 

Allen, your link to PHRF critical dimensions is stale. The new link is http://www.ussailing.org/wp-content/uploads/DARoot/Offshore/PHRF/Critical%20Dimensions.pdf

 

Thanks. That gives me something to do as I wait for my boat to get out of insurance purgatory.

 

I should point out that I do not do the kind of comparisons that the OP is doing. However, I do link to sources of used sails for any specific boat based on the dimensions of the boat. http://L-36.com/find_used_sails.php

 

The data on the sail inventory is automatically updated each week so at least some things are not stale.

12 metre, were you ever able to track down an Excel or CSV file?

Nah,  never really made any effort to locate one.  I have pretty much all the info I need and when I do need additional info, it is usually for just a few specific vessels so it only takes a couple of minutes to find and summarize from places like Sailboatdata.  I have little need for specific multi-boat comparisons - but I thought it would be handy for other users.

Apparently Alex W has an Excel file, so you could contact him.

Hey Folks, 

I'm after a spreadsheet of all that sailboat data as well. Its for my final year Naval Arch. design project, and for future reference. How can I get in touch with Alex W.? 

If not I was going to make a program with scrapy and crawl sailboatdata.com with it...I'm just really busy with all my other subjects so I'd rather save the time for studying if possible!

I am not sure if everyone heard but Randy Browning, who founded sailboatdata.com, unfortunately passed away earlier this year.  A gentleman by the name of Bruce McArthur has taken over.

That is sad. I never heard of his name so far, but I frequently use that site and found it to be among the best sources for quick searches and comparisons.

Thanks for the info, best of luck to Mr. McArthur and my sympathies to friends and families of Mr. Browning.

This is my scrape: https://1drv.ms/x/s!AqokoOqNPTKZjGgqLIpogifqsape

It is from 2013, and there are some errors (though I think I cleaned up most).  

I was sad to hear about Randy's passing, and I'm glad to know that another person is keeping it going.  It is a helpful resource.

Wowsers, that's a helpful spreadsheet.

I've referred sailboatdata.com so many times.  Looking forward to playing with the data. Thanks to Mr. W, and the folks behind sailboatdata.com
