I created a tool to help me in my sailboat search and I thought I'd share it with you all: sailboatlocator.com
(sorry can't post link because this is my first post). It runs on a fairly small server and it's still in beta so I'm not sure what will happen if it gets heavier traffic but I guess we'll see. It uses gmail authentication so you need a gmail address to use it.
The problem: I have a list of about 30 boats that I'm interested in (I'm still at a very preliminary stage of my search). Going on yatchworld, sailboatlistings, boat trader and querying these 30 boats ends up in a total of 90 queries, takes too much of my time.
provides a solution: you enter a list of sailboat you are interested in (it supports about 6000+ types of sailboat at this point) and enter a list of states you are considering (e.g., Washington state and Oregon), and the search engine gives you a nice summary of all boats which match your search. It does so by querying other search engines periodically, and it can email you if a new boat arrives on the market.
There can be a delay of 15-60 minutes
between the time you create a search and the time results start appearing since it needs to query other engines.
It only works in the US for now. Feel free to use it and send me feedback if you have any (e.g., if you have issues, think of new features or if you know of a similar service out there)
p.s. here's a screenshot of an example search results
