But that is not an outdated design, that is a traditional boat and a completely different matter. That's for the ones that like to sail the real thing like it was sailing and cruising a century ago and that has its charms, like driving a beautiful classic old car.
I can understand why you want one since I had a 80 year's old traditional boat from that family
but Portuguese tradition related instead of British. A distant relative of the Caravelas, a Canoa. Charming thing to sail even if charm has nothing to do with efficiency but certainly with sailing pleasure.
I still remember what was coming to an anchorage sailing (I rarely used the engine) and see all the other cruisers taking photos
