SMIA at a Glance

A Bit of Background

The object of the Association and this Website is to provide an opportunity to exchange ideas and stimulate discussion about owning and sailing boats from the Snapdragon, Mirage and Invader classes. We also aim to provide assistance to others of the SMIA fraternity via our Facebook Page

The Association is open to all owners, past and present, of yachts which were built by Thames Marine Ltd., at Canvey Island or by Boating Scene. Further details about the Association can be found under the “Association” button above. Members have access to the “Members pages” which are password protected where you can find out about Association’s activities as well as more technical info about the boats. Members also receive a twice yearly Journal with stories, hints a tips about the boats.  

The Association Committee are keen to hear from members (or potential members) who would like to get more involved in helping to run the Association.
