I don't know any details about Freja, but Cal Yachts Online
has a lot of information about Cals in general, and the Cal 29 in particular.
And if you're looking for some fun the first weekend of October, consider coming out for the Good Old Boat Regatta (see Good Old Boat: Regattas for good old boats
for info on last year's event). We've had a Cal 29 class start for the past few years; it's definitely low-key and lots of fun and a chance to meet others with similar boats.
