The OP asked for, and got, opinions and thoughts based on the facts in evidence and the experience of the people he asked.
Its a fact that many (most?) buyers underestimate what its going to cost to own a boat after its bought. Its a fact that its going to cost a lot more to own a 40'+ boat than a smaller one. Its a fact that no reasonable person would recommend someone setting off on a "heavy bluewater" excursion without getting some level of sailing experience beyond what would be considered "novice" and at least enough to know if the boats they were considering are up to their plans. Its a reasonable assumption that a "novice" sailor looking for their first sailboat will not have a good handle on what owning a 40'+ boat entails.
No one said he needed to start on a Laser, or that coastal cruising was beyond reasonable grasp, or that they were stupid or foolish to dream of "heavy bluewater" sailing. The opinion offered was only that a 40+ foot first boat is taking a big step and that one should build some reasonable level of training and experience before setting off on any "bluewater" passage.
But thanks for the chastizing. I will keep my mouth shut hence forth.
