ehhh i figure 1/4 million can buy me a decent 50 footer ... most people would consider that a yacht and not a simple boat ... some may argue only 100 foot + counts as a true luxury yacht ...
Happy shopping (good luck with that 1/4 mill)

oh i know there's definitely a difference between a yacht and a luxury yacht ... the same way there's a difference between a used honda and a new lamborghini
