Most of us become intimately familiar with the Dunning-Kruger effect before reaching twenty-five. For those who don't, there's the heady days of introductory boat ownership, marriage, university, careers, child rearing, et al, to scorch the effect indelibly into one's soul in letters of fire.
As in marriage, if you get things wrong, the outcome will descend upon you as gently as winding sheets of flame.
My advice to anyone thinking of buying a boat, fueled only by their dreams, without a broad spectrum of boating related experiences to draw upon, is to think long and hard about why they think that boat ownership is an answer to their particular life's question.
My experience has taught me that idealizing outcomes leads to disillusion, frustration, and regret.
"Men go to sea, before they know the unhappiness of that way of life; and when they have come to know it, they cannot escape from it, because it is then too late to choose another profession; as indeed is generally the case with men, when they have once engaged in any particular way of life."
If you long to have one more dream/preconceived notion die a ignominious writhing death, buy a boat.
