Question

Answer 1

How much do you have?

Answer 2

WOW man, what a wonderful idea... and what great timing.  You really lucked out on this one.  Right now, the "Becky Thatcher" is for sale on E-Bay... She is a beautifully refurbished sternwheeler which would make a fantastic  dinner cruise, party or touring vessel... even a Bed & Breakfast, don't know what she will auction off for, but my guess is that she is a deal, and in fact - a steal for anything under $400,000.00

Course, you might find something cheaper in an old ship or old ferry... but I seriously doubt you will find a seaworthy sailboat that will handle 50 - 100 people for less than $1,000,000.00
