Invitation to all of a pure heart
When you''re going to apply sweeping generalities to a specific boat you really ought to make a bit of an effort to learn more about the boat than you have.
James Wharram''s Gaia (built to his Pahi 63 design) is reported by those who have sailed on her to be very comfortable, and when thrills become more important than comfort (though the boat was designed for cruising with a dozen or 15 people) it can be sailed faster than any boat approaching its cost.
And it does sail to windward, as well as any monohull costing twice as much to build I reckon, and with a lot more comfortable motion. There is a lot of information available to those interested in the facts, rather than maintaining a particular bias, at James Wharram''s website -- wharram.com
