[I know this is an old thread, but better to build some information here on this elusive make of sailboat I think]
I understand Targa only makes power boats now: Home
There is a Targa 101, a center cockpit sloop, advertised for sale in the SF Bay Area. Some brochure pics: Targa 101: Alkuperäisiä esitteitä
And data on the Targa 96 here: TARGA 96 Sailboat details on sailboatdata.com
I'd be interested in hearing from anyone who has sailed these Finnish boats...
