Shoot, that probably would make a difference. Sorry, @LAFFNVEGAS, the ball appears to be back in your court.
It does appear that the few other pictures of the lifeboats, show more obstruction. Unfortunately, there is not a picture that is positioned like H4138.
@FlorenceItaly, here's a YouTube video from VH4041 that shows, at least, the height of the lifeboat through the glass doors.
