Re: Learning to sail w/o water....
Seriously, take an ASA course, then get a sunfish or daysailor < 20' and learn to sail it. 29'+ is way too distracting with all the winches, pumps, lights, etc. Keep the dream, but create a plan to realize it in a step-wise fashion. The boats that you mention are fine weekenders.... you're a very long way from going offshore so don't even worry about what boat to get.
