Umm... Cam, he's asking about a Hans Christian
, not a Cape Dory 30...
You don't say which hans christian you're looking at specifically. If it is the HC33, then one of the reasons there is a big price difference, is the HC33 is a lot bigger than the A30.
The HC33 is almost twice the displacement of the A30, about 3' more beam, and about 7' more on the waterline.
The HC33 is 41' LOA, versus the 30.25' for the A30.
The HC33 also has much larger tankage (80 gal Diesel, 90 gal. water) than the A30, being designed as a bluewater passagemaker, which the A30, although capable of doing so, was not specifically designed to do.
While both are capable of making bluewater passages, and both are basically full-keel, traditional designed sloop-rigged sailboats—these are significantly different boats... and the HC33 will cost a lot more in the long run to store, dock, haul out, etc... as much of these fees are related directly to the LOA of the boat.
The A30 will probably be the better of the two boats, especially when it comes to light air sailing, as it has an SA/D ratio of 15.1 vs. 10.0 for the HC33... However, once the wind picks up, the HC33 will ultimately go faster, having a much longer waterline.
