I own and admin the danish site http://hr-club.dk/ which is a union and forum for all Hallberg Rassy (http://www.hallberg-rassy.com) sailboats, and until now, mainly in Denmark, where we have 158 boats registrered:
The Hallberg Rassy is built in Sweden, and very popular up there, but HR-Club has only reached 8 boats from Sweden, and that we would like to grow!
The site can be read by everyone, due to the Google Language Selector, in the upper right corner of the site, and therefore the site have members from Germany, Holland, Italy and even USA too.
There have been produced over 10.000 Hallberg Rassy's since 1964, so the market is quite big.
What I need, is an idea to reach as many Hallberg Rassy owners worldwide as possible, but mainly in sweden to start with! I have thought of contacting all swedish harbours, but I am not a marketing guy, and I am sure, that the person with the right marketing skills, will be able to solve the case much easier than me!
If you are the right person for the task, then please let me know your background, and the basic of your idea, to hire you in.
A happy sailor and entrepreneur :-)
