    Comparing Specs

    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.

    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.

    Update: Based on feedback, I added searching by builder, designer name, displacement, and SA/disp ratio. Check it out again if you have a chance. https://sailboatpages.com

    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...

    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? 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.

    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.

    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.

    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
