Hi Mate, I think the Columbias were mostlly intended as bare boat charter packages. There was the 27,34 and I think a 42 or 44.
One thing is always said about them and that is that they are incredibly roomy.
One thing that is NOT often said about them is that they sail well.
On www.boatpoint .com.au you will find lots of boats in the size and price range of the Columbias that will certainly out sail a Columbia.
A general rule of thumb with yachts is that the faster they are the more seaworhty they are.
Other boats worthy of consideration are Holland 25s, Top Hat 25s, Tasman 26s, Sonata 8s and the Endeavour and Compass Yachts. Cheers Cisco
