Kaufman 47 - Any of you who know me or read my stuff know that Quetzal, my much loved boat, is a Kaufman 47. I have sailed her 66,000 miles in the last six years including four transatlantic passages. We've sailed the length and breath of the Med several times, around the Caribbean
, and north to Newfoundland
. The boat sails
brilliantly. We've averaged 150 miles a day through it all, and don't motor
much. Mike Kaufman's hull
shape is a cross between a Beneteau
456 and a Hylas
49. I have always loved the low slung, powerful look of Kaufman and Ladd designs. Think of the Skye 51 and the Albin Nimbus as other examples. The Kaufman 47 is well balanced making it easy on the autopilot
and also sails
great with just a headsail, an effortless way to cross oceans. The hull
has endured a pounding, including a punch on the chin from a nasty Italian tornado. We've ridden out three major deep-sea gales, major as in force 9 and 10 major. Oh yes, Quetzal has her quirks, but what boat doesn't. The Kaufman 49 is the same boat with a reverse transom. And there's no denying it that the Kaufman 47 was inspired by the S&S Swan 47. Side by side they're hard to tell apart. One way is the cockpit
, the Kaufman's is much more comfortable.
