Is there a big enough boat?

I am so inspired by and so enamored of the blog of Jennifer, which chronicles education on board a boat.  Jennifer is sailing with her husband, Capt. Hal, and their daughter, Marianna.  The blog is fairly new, but the nature pictures are breathtaking and her description of a typical morning cuppa is anything but typical.  What an amazing opportunity they are offering their daughter.  Talk about atmosphere!  I wonder if there's a boat big enough for 8 children, many of whom must play soccer daily or risk withdrawal symptoms...
