Re: What does "Tunnel Hull" mean?
Nathan ,a tunnel hull is one in which the centerline of boats bottom has a contoured undercut and allows the engines lower unit or outdrive to run closer to flush with bottom of boats hull.This undercut creates a water tunnel,hence the term"tunnel hull."They use a lot of them here on the Texas gulf coast for fishing flats ,which allows the boat to run shallower without lower unit running ground.
