My wife and kids just gave me a 13 foot Juca for my Birthday(used of course) and it has a 'vent' between the bottom of the transom and the inflatable floor. It is not a tear it looks like the boat was made that way. My Brother in law has a Juca but it is an older boat according to him and has no 'vent'. It doesn't leak any water in but looks a bit wierd. Anyone else seen this?
