Depends on what state the second hand Taipan is.

In the UK I'd say oldish F16 are going for £3000 at a minimum (good luck finding one at that price however) up to £9000 for a recent boat in excellent condition. Extras like trailers/trolley/covers/extra sails make the price go up fairly quickly.

Anything that floats with a working set of sails under £4500 is probably going to be sold in a day... The marketplace is fairly hungry for used F16 in that price range: I know 4 people looking for one right now...

COnsidering your location I guess you're fishing to see if it would be a good idea to ship your Taipan to sell it here? I'd say that unless you have a really competitive way of shipping it in, I don't think it's going to be worth it. The shipping cost and the VAT are going to make a big dent...
