No, and don't really want one, have never missed it.
We have all that crap at home. Our 2 months per summer on the boat is our family and decompression time. We read a lot, play chess and scrabble, read some more, watch sunsets and go to bed early.
In particular my son, who is now 12, has never missed the TV. He devours books on our cruises, and just won his school's spelling bee (again). I think there is a connection.
We have a perfect spot to mount one, but I'm thinking an oil painting instead.
Maine Sail, I'll look for your boat next summer.
