Well, if I were a hotshot stock broker with a nice boat, I'd want to be able to log into my favorite website and check my portfolio... Not to mention telecommuting - might need to catch up on emails between beers.
Fishing can become boring after a while. Might need to let out some agression on GTA or NFS.
Most guys with a 50' Bayliner are keen to the latest toys. And many of them live on their boats during the weekends. Just head down to any private boat club! I'd love to have that kind of convenience during a long weekend.
