Used to have a Teliga 21 in the Lakes. Polish built - in Gadansk - then imported into Britain. Loads of fun to sail, just like a big dinghy with a lid. Now produced as the Sportina, which was being advertised until reasonably recently. If no-one else can give you further info. let me know and I'll trawl through the filing cabinet and see if I can find any contact numbers.
Teliga 21 - 20'4" x 17'11" x 8'2" x 11"-4'3" (lift keel) 4 berths.
Made in Poland from 1988 and still available. Strongly built but not over-ballasted.
Takes an outboard up to 6hp.
