You definitely have to be somewhat batty to go into large boat ownership unless you have major money to burn. It's a much better plan to butter up to a future BTC trillionaire, use one's masculine wiles to marry them and then sail away into the future with their gains.
Or just rent.
Always buy a boat smaller than you think you can afford. It will usually prove you wrong... And it's about the time of year to have mine serviced again. :/
